DESCRIPTION

The dgstsum utility takes each specified input file and produces a checksum called a message digest. By default, dgstsum uses the md5 digest format. Alternatively, it can compare previously generated output to see if the message digests are still the same (that is, the files have not changed).

The md2sum, md4sum, md5sum, mdc2sum, ripemd160sum, shasum, sha1sum, sha224sum, sha256sum, sha384sum, sha512sum, and whirlpoolsum utilities are similar to dgstsum except that instead of specifying the digest format with the -d, the name of the utility identifies the digest format used (for example, the shasum utility uses the sha digest format.

Options

-b 
--binary 

Treats all files as binary. No end-of-file or end-of-line conversions take place. When comparing against text files from UNIX systems, this may yield different checksums.

-c file 
--check=file 

Specifies a check file. This check file contains the output from a previous dgstsum command. Each line in the check file contains a message digest, a flag specifying if the file is binary or text, and a file name. dgstsum opens each listed file, calculates its current message digest and compares it to the corresponding digest from the previous output. As each file's digests are compared, dgstsum displays the file's name and either OK if the digests match or FAILED if they do not. However, the --status option, described below, can suppress this display.

Note:

For this option to work correctly, both the previous and new digests must use the same digest format. For example, if you created a saved output file named md2out from a dgstsum -d md2 command, you could use either of the following commands to compare the current digests to those in md2out: 

dgstsum -d md2 -c md2out
md2sum -c md2out

-d digesttype 

Specifies the digest format to be used when calculating message digests. The following formats may be specified for digesttype: 

md2
md4
md5
mdc2
ripemd160
rmd160
sha
sha1
sha224
sha256
sha384
sha512
whirlpool

Note:

rmd160 is simply an another name for the ripemd160 format.

-h 
--help 

Displays a usage message and exits.

-s string 
--string=string 

Computes the message digest for just the specified string rather than for a file. The message digest generated is identical to that of a file containing just string.

--status 

Suppresses the display of file names and either OK or FAILED for each line in the check file. Instead, the utility returns an exit status of 0 when all files in the check file generate the same message digest as in the check file or an exit status of 1 when at least one file generates a different message digest. This option is only applicable with -c or --check.

-t 
--text 

Treats all input files as text files. This is the opposite of -b. End-of-file and end-of-line conversions are performed so that UNIX and Windows text files whose only differences are the end-of-line characters used produce identical message digests.

Note:

This option is not recommended for binary files.

-V 
--verbose 

Does nothing. This option is provided for compatibility with other versions of these utilities.

-v 
--version 

Displays version number.

-w 
--warn 

Displays warnings about malformed lines in the check file specified with the -c (or --check) option. Normally, when this option is not specified, malformed lines are simply ignored.

This option is only applicable with -c or --check.

DIAGNOSTICS

Possible exit status values are:

0 

Successful completion.

1 

An error occurred or when -c or --check is specified, one or more files listed in the check file now generate a different checksum.

2 

A usage error occurred.
