I often need to compare two Perl files sans comments. This mostly works: egrep -v '^#' file1.pl > file1.tmp egrep -v '^#' file2.pl > file2.tmp diff -B file1.tmp file2.tmp
(yes, it breaks for perldoc style comments, comments on lines w/ code, # characters inside HERE docs, and probably other cases-- just an approximation) I also often need to see if two files contain the same lines, minus comments and allow duplicates. This mostly works: egrep -v '^#' file1.txt | sort | uniq > file1.tmp egrep -v '^#' file2.txt | sort | uniq > file2.tmp diff -B file1.tmp file2.tmp;: comm would also work here I could easily Perl script these two tasks, but my question is: has anyone created a "super diff" that does this sort of thing and more? -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology. We feel that resistance to new ideas and technology is unwise and ultimately futile. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
