Description

MD5 - Command Line Message Digest Utility SYNOPSIS

md5 [ -csignature ] [ -l ] [ -n ] [ -u ] [ -v ] [ -dinput_text | infile… ]

OPTIONS

-csignature Computes the signature of the specified infile or the string supplied by the -d option and compares it against the specified signature. If the two signatures match, the exit status will be zero, otherwise the exit status will be 1. No signature is written; only the exit status is set. The signature to be checked must be specified as 32 hexadecimal digits. -dinput_text A signature is computed for the given input_text (which must be quoted if it contains white space characters) instead of input from infile or standard input. If input is specified with the -d option, no infile should be specified. -l Use lower case letters for hexadecimal digits “a” through "f". By default, upper case letters are used. Note that the signature argument to the -c option may use upper or lower case hexadecimal digits (or a mix) regardless of the setting of this option. -n Suppress printing the file name (or "-" for standard input) after the hexadecimal signature. -ofname Write output to fname. If fname is "-", output is written to standard output, which is the default is no -o option is specified. -u Print how-to-call information. -v Print version information. FILES

If no infile or -d option is specified or infile is a single "-", md5 reads from standard input. A single "-" on the command line causes all subsequent arguments to be treated as file names even if they begin with "-". If no -o option is specified or the fname is a single "-", output is sent to standard output. Input and output are processed strictly serially; consequently md5 may be used in pipelines.
