(Perl) comparing the checksums of two files with Perl and cksum

Sun, 05 Jul 2009 21:17:39 GMT

This one-liner helps to determine if two or more files have the same checksum. It works by piping the output from `cksum` to Perl, which takes note of the first checksum and compares each subsequent file's checksum to that value. Assume an example session where we have three identical files and two that are different >echo bart > bart >cp bart bart1 >cp bart bart2 >echo milhouse > mvh >echo lisa > lisa two files with the same checksum, produce no output >cksum bart bart1 | perl -ane '$x ||= $F[0]; warn if $x != $F[0];' if a there is a different checksum, the line numbers printed are the indexes of those files >cksum bart bart1 mvh bart2 lisa | perl -ane '$x ||= $F[0]; warn if $x != $F[0];' Warning: something's wrong at -e line 1, line 3. Warning: something's wrong at -e line 1, line 5.
