"OPTION -h"
Usage: shasum [OPTION]... [FILE]...
Print or check SHA checksums.
With no FILE, or when FILE is -, read standard input.

-b, --binary read in binary mode
-c, --check read SHA sums from the FILEs and check them
--tag create a BSD-style checksum
-t, --text read in text mode (default)
-U, --UNIVERSAL read in Universal Newlines mode
produces same digest on Windows/Unix/Mac
-0, --01 read in BITS mode
ASCII '0' interpreted as 0-bit,
ASCII '1' interpreted as 1-bit,
all other characters ignored
The following five options are useful only when verifying checksums:
--ignore-missing don't fail or report status for missing files
-q, --quiet don't print OK for each successfully verified file
-s, --status don't output anything, status code shows success
--strict exit non-zero for improperly formatted checksum lines
-w, --warn warn about improperly formatted checksum lines
-h, --help display this help and exit
-v, --version output version information and exit
When verifying SHA-512/224 or SHA-512/256 checksums, indicate the
algorithm explicitly using the -a option, e.g.
shasum -a 512224 -c checksumfile
The sums are computed as described in FIPS PUB 180-4. When checking,
the input should be a former output of this program. The default
mode is to print a line with checksum, a character indicating type
(`*' for binary, ` ' for text, `U' for UNIVERSAL, `^' for BITS),
and name for each FILE. The line starts with a `\' character if the
FILE name contains either newlines or backslashes, which are then
replaced by the two-character sequences `\n' and `\\' respectively.

--helpcalc Opens built-in or online Help on Calc.
--helpdraw Opens built-in or online Help on Draw.
--helpimpress Opens built-in or online Help on Impress.
--helpbase Opens built-in or online Help on Base.
--helpbasic Opens built-in or online Help on Basic scripting
language.
--helpmath Opens built-in or online Help on Math.
--version Shows the version and quits.
--nstemporarydirectory
(MacOS X sandbox only) Returns path of the temporary
directory for the current user and exits. Overrides
all other arguments.
General arguments:
--quickstart[=no] Activates[Deactivates] the Quickstarter service.
--nolockcheck Disables check for remote instances using one
installation.
--infilter={filter} Force an input filter type if possible. For example:
--infilter="Calc Office Open XML"
--infilter="Text (encoded):UTF8,LF,,,"
--pidfile={file} Store soffice.bin pid to {file}.
--display {display} Sets the DISPLAY environment variable on UNIX-like
platforms to the value {display} (only supported by a
start script).
User/programmatic interface control:
--nologo Disables the splash screen at program start.
--minimized Starts minimized. The splash screen is not displayed.
--nodefault Starts without displaying anything except the splash
screen (do not display initial window).
--invisible Starts in invisible mode. Neither the start-up logo nor
the initial program window will be visible. Application
can be controlled, and documents and dialogs can be
controlled and opened via the API. Using the parameter,
the process can only be ended using the taskmanager
(Windows) or the kill command (UNIX-like systems). It
cannot be used in conjunction with --quickstart.
--headless Starts in "headless mode" which allows using the
application without GUI. This special mode can be used
when the application is controlled by external clients
via the API.
--norestore Disables restart and file recovery after a system crash.
--safe-mode Starts in a safe mode, i.e. starts temporarily with a
fresh user profile and helps to restore a broken
configuration.
--accept={connect-string} Specifies a UNO connect-string to create a UNO
acceptor through which other programs can connect to
access the API. Note that API access allows execution
of arbitrary commands.
The syntax of the {connect-string} is:
connection-type,params;protocol-name,params
e.g. pipe,name={some name};urp
or socket,host=localhost,port=54321;urp
--unaccept={connect-string} Closes an acceptor that was created with
--accept. Use --unaccept=all to close all acceptors.
--language={lang} Uses specified language, if language is not selected
yet for UI. The lang is a tag of the language in IETF
language tag.
Developer arguments:
--terminate_after_init
Exit after initialization complete (no documents loaded)
--eventtesting Exit after loading documents.
New document creation arguments:
The arguments create an empty document of specified kind. Only one of them may
be used in one command line. If filenames are specified after an argument,
then it tries to open those files in the specified component.
--writer Creates an empty Writer document.
--calc Creates an empty Calc document.
--draw Creates an empty Draw document.
--impress Creates an empty Impress document.
--base Creates a new database.
--global Creates an empty Writer master (global) document.
--math Creates an empty Math document (formula).
--web Creates an empty HTML document.
File open arguments:
The arguments define how following filenames are treated. New treatment begins
after the argument and ends at the next argument. The default treatment is to
open documents for editing, and create new documents from document templates.
-n Treats following files as templates for creation of new
documents.
-o Opens following files for editing, regardless whether
they are templates or not.
--pt {Printername} Prints following files to the printer {Printername},
after which those files are closed. The splash screen
does not appear. If used multiple times, only last
{Printername} is effective for all documents of all
--pt runs. Also, --printer-name argument of
--print-to-file switch interferes with {Printername}.
-p Prints following files to the default printer, after
which those files are closed. The splash screen does
not appear. If the file name contains spaces, then it
must be enclosed in quotation marks.
--view Opens following files in viewer mode (read-only).
--show Opens and starts the following presentation documents
of each immediately. Files are closed after the showing.
Files other than Impress documents are opened in
default mode , regardless of previous mode.
--convert-to OutputFileExtension[:OutputFilterName] \
[--outdir output_dir] [--convert-images-to]
Batch convert files (implies --headless). If --outdir
isn't specified, then current working directory is used
as output_dir. If --convert-images-to is given, its
parameter is taken as the target filter format for *all*
images written to the output format. If --convert-to is
used more than once, the last value of
OutputFileExtension[:OutputFilterName] is effective. If
--outdir is used more than once, only its last value is
effective. For example:
--convert-to pdf *.odt
--convert-to epub *.doc
--convert-to pdf:writer_pdf_Export --outdir /home/user *.doc
--convert-to "html:XHTML Writer File:UTF8" \
--convert-images-to "jpg" *.doc
--convert-to "txt:Text (encoded):UTF8" *.doc
--print-to-file [--printer-name printer_name] [--outdir output_dir]
Batch print files to file. If --outdir is not specified,
then current working directory is used as output_dir.
If --printer-name or --outdir used multiple times, only
last value of each is effective. Also, {Printername} of
--pt switch interferes with --printer-name.
--cat Dump text content of the following files to console
(implies --headless). Cannot be used with --convert-to.
--script-cat Dump text content of any scripts embedded in the files
to console (implies --headless). Cannot be used with
--convert-to.
-env:<VAR>[=<VALUE>] Set a bootstrap variable. For example: to set
a non-default user profile path:
-env:UserInstallation=file:///tmp/test
Ignored switches:
-psn Ignored (MacOS X only).
-Embedding Ignored (COM+ related; Windows only).
--nofirststartwizard Does nothing, accepted only for backward compatibility.

-noI do not compress inode table
-noId do not compress the uid/gid table (implied by -noI)
-noD do not compress data blocks
-noF do not compress fragment blocks
-noX do not compress extended attributes
-no-compression do not compress any of the data or metadata. This is
equivalent to specifying -noI -noD -noF and -noX
Filesystem build options:
-reproducible build filesystems that are reproducible (default)
-not-reproducible build filesystems that are not reproducible
-mkfs-time <time> set filesystem creation timestamp to <time>. <time> can
be an unsigned 32-bit int indicating seconds since the
epoch (1970-01-01) or a string value which is passed to
the "date" command to parse. Any string value which the
date command recognises can be used such as "now",
"last week", or "Wed Feb 15 21:02:39 GMT 2023"
-all-time <time> set all file timestamps to <time>. <time> can be an
unsigned 32-bit int indicating seconds since the epoch
(1970-01-01) or a string value which is passed to the
"date" command to parse. Any string value which the date
command recognises can be used such as "now", "last
week", or "Wed Feb 15 21:02:39 GMT 2023"
-root-time <time> set root directory time to <time>. <time> can be an
unsigned 32-bit int indicating seconds since the epoch
(1970-01-01) or a string value which is passed to the
"date" command to parse. Any string value which the date
command recognises can be used such as "now", "last
week", or "Wed Feb 15 21:02:39 GMT 2023"
-root-mode <mode> set root directory permissions to octal <mode>
-root-uid <value> set root directory owner to specified <value>,
<value> can be either an integer uid or user name
-root-gid <value> set root directory group to specified <value>,
<value> can be either an integer gid or group name
-all-root make all files owned by root
-force-uid <value> set all file uids to specified <value>, <value> can be
either an integer uid or user name
-force-gid <value> set all file gids to specified <value>, <value> can be
either an integer gid or group name
-default-mode <mode> tar files often do not store permissions for
intermediate directories. This option sets the default
directory permissions to octal <mode>, rather than 0755.
This also sets the root inode mode
-default-uid <uid> tar files often do not store uids for intermediate
directories. This option sets the default directory
owner to <uid>, rather than the user running Sqfstar.
This also sets the root inode uid
-default-gid <gid> tar files often do not store gids for intermediate
directories. This option sets the default directory
group to <gid>, rather than the group of the user
running Sqfstar. This also sets the root inode gid
-pseudo-override make pseudo file uids and gids override -all-root,
-force-uid and -force-gid options
-exports make the filesystem exportable via NFS
-no-sparse do not detect sparse files
-no-fragments do not use fragments
-no-tailends do not pack tail ends into fragments
-no-duplicates do not perform duplicate checking
-no-hardlinks do not hardlink files, instead store duplicates
Filesystem filter options:
-p <pseudo-definition> add pseudo file definition. The definition should
be quoted
-pf <pseudo-file> add list of pseudo file definitions. Pseudo file
definitions in pseudo-files should not be quoted
-ef <exclude_file> list of exclude dirs/files. One per line
-regex allow POSIX regular expressions to be used in exclude
dirs/files
-ignore-zeros allow tar files to be concatenated together and fed to
Sqfstar. Normally a tarfile has two consecutive 512
byte blocks filled with zeros which means EOF and
Sqfstar will stop reading after the first tar file on
encountering them. This option makes Sqfstar ignore the
zero filled blocks
Filesystem extended attribute (xattrs) options:
-no-xattrs do not store extended attributes
-xattrs store extended attributes (default)
-xattrs-exclude <regex> exclude any xattr names matching <regex>. <regex> is a
POSIX regular expression, e.g. -xattrs-exclude '^user.'
excludes xattrs from the user namespace
-xattrs-include <regex> include any xattr names matching <regex>. <regex> is a
POSIX regular expression, e.g. -xattrs-include '^user.'
includes xattrs from the user namespace
-xattrs-add <name=val> add the xattr <name> with <val> to files. If an
user xattr it will be added to regular files and
directories (see man 7 xattr). Otherwise it will be
added to all files. <val> by default will be treated as
binary (i.e. an uninterpreted byte sequence), but it can
be prefixed with 0s, where it will be treated as base64
encoded, or prefixed with 0x, where val will be treated
as hexidecimal. Additionally it can be prefixed with
0t where this encoding is similar to binary encoding,
except backslashes are specially treated, and a
backslash followed by 3 octal digits can be used to
encode any ASCII character, which obviously can be used
to encode control codes. The option can be repeated
multiple times to add multiple xattrs
Sqfstar runtime options:
-version print version, licence and copyright message
-force force Sqfstar to write to block device or file
-exit-on-error treat normally ignored errors as fatal
-quiet no verbose output
-info print files written to filesystem
-no-progress do not display the progress bar
-progress display progress bar when using the -info option
-percentage display a percentage rather than the full progress bar.
Can be used with dialog --gauge etc.
-throttle <percentage> throttle the I/O input rate by the given percentage.
This can be used to reduce the I/O and CPU consumption
of Sqfstar
-limit <percentage> limit the I/O input rate to the given percentage.
This can be used to reduce the I/O and CPU consumption
of Sqfstar (alternative to -throttle)
-processors <number> use <number> processors. By default will use number of
processors available
-mem <size> use <size> physical memory for caches. Use K, M or G to
specify Kbytes, Mbytes or Gbytes respectively
-mem-percent <percent> use <percent> physical memory for caches. Default 25%
-mem-default print default memory usage in Mbytes
Expert options (these may make the filesystem unmountable):
-nopad do not pad filesystem to a multiple of 4K
-offset <offset> skip <offset> bytes at the beginning of FILESYSTEM.
Optionally a suffix of K, M or G can be given to specify
Kbytes, Mbytes or Gbytes respectively.
Default 0 bytes
-o <offset> synonym for -offset
Miscellaneous options:
-fstime <time> alternative name for mkfs-time
-root-owned alternative name for -all-root
-noInodeCompression alternative name for -noI
