The file -shall be formatted as the output of the utility -when this option is not used. See the -.B STDOUT -section for more information. If a file is listed -multiple times, it need only match one of the -checksums listed for the file. - -The length of the listed checksums need not match -the length output by this utility; before the -checksums are compared, they are truncated to the -shorter of the two checksums. -.TP -.B -t -Read in text mode when computing hashes. -.TP -.BR -W \ \fIoptions\fP -Comma-sepearated list of implementation-specific -options. The following options are supported: -.RS -.TP -.BI output= format -.I format -shall be -.RB \(dq lowercase \(dq -if the checksums shall be printed in lowercase -hexadecimal format (default), -.RB \(dq uppercase \(dq -for uppercase hexadecimal format, or -.RB \(dq binary \(dq -for binary format without anything but the -checksum printed to standard output. This -option is ignored if the -.B -c -option is used. -.TP -.BI input= format -.I format -shall be -.RB \(dq binary \(dq -if the files are be read in binary mode, -.RB \(dq text \(dq -if the files shall be read in text mode, or -.RB \(dq hexadecimal \(dq -they shall be decoded from hexadecimal to -binary. If the -.B -c -option is used, the mode specification -associated with a file is overrides this -behaviour for that file if the line -specifies hexadecimal mode. -.TP -.B recursive -If a -.I file -operand is a directory, the checksum is computed for -all files recursively. This option is ignored if the -.B -c -option is used. -.TP -.B no-recursive -The utility shall traverse directories. -(This is the default behaviour). -.TP -.B xdev -Implies -.B -W recursive -but also allows the recursion across mountpoints. -.TP -.B no-xdev -Disable recursion across mountpoints. -(This is the default behaviour). -Note that this does not disable -recursion by itself. -.TP -.B xlink -Implies -.B -W recursive -but also allows the recursion across symbolic links. -.TP -.B no-xlink -Disable recursion across symbolic links. -(This is the default behaviour). -Note that this does not disable -recursion by itself. -.RE -.TP -.B -w -Warn about, but skip, lines that are not properly -formatted. -.TP -.B -z -Use NUL byte as line ending instead of LF. -.PP -There is no difference between binary mode and text mode, -so the -.B -b -and -.B -t -options are ignored, except that they undo -.BR "-W input=hexadecimal" . - -.SH OPERANDS -The following operand is supported: -.TP -.I file -The file to read and compute the checksum for, or if the -.B -c -option is used, use as the listing of files and checksums -to verify the files against. If dash -.RB (' - ') -is used or if no file operand is specified, standard input -will be used. - -.SH STDOUT -If the -.B -c -option is not used, the utility shall print the following -line for each calculated checksum, however there are options -that modify the format; see the -.B OPTIONS -section for more information: -.PP -.RS -.B \(dq%s %c%s\en\(dq, -.RI < hash >\fB,\fP -.RI < mode >\fB,\fP -.RI < file > -.RE -.PP -where -.I mode -is SP (' ') for text mode, an asterisk -.RB (' * ') -for binary mode, or a pound sign -.RB (' # ') -for hexadecimal mode; however if there is no difference -between binary mode and text mode and either is selected, -SP (' ') (text mode) is used. -.PP -If the -.B -c -option the output shall be on the format: -.PP -.RS -.B \(dq%s: %s\en\(dq, -.RI < file >\fB,\fP -.RI < validity > -.RE -.PP -where -.I validity -is an implementation specified string -that describes whether the checksum was valid (possibly -with remarks), the file did not exist, the file could -not be read (possibly with error information), or if -the checksum was invalid or could not be compared -(possibly with remarks). The -.B -z -option does not modify the line ending. - -.SH EXIT STATUS -The following exit values are returned: -.TP -0 -Successful completion. -.TP -1 -Checksums did not match or a file did not exist. -.TP -2 -An error occurred. - -.SH NOTES -Other implementations do not necessarily recognise the -hexadecimal mode specifier -.RB (' # ') -in checksum list files. -.PP -The -.B -c -option accepting truncated checksums is an -implementation-specific behaviour. -.PP -Be advised that MD2 is partially compromised. - -.SH SEE ALSO -.BR anysum (1) |
