Re: Save all but line 32!

Not as fast and doesn't handle a list of files, but for entertainment value:

perl -MTie::File -e 'tie @file, 'Tie::File', $ARGV[0]; splice @file, 3
+1, 1;' filename
[download]

(Tie::File is in the standard lib now.)

~~Some~~ None of the other solutions will not correctly handle a list of files either ~~(only the ones using `$.` will)~~. And this one is easily extended to do so: `perl -MTie::File -e 'tie(@file, 'Tie::File', $_) and splice @file, 31, 1 for @ARGV' file1 file2 file3` Update: zigdon is right. I should have tested. Makeshifts last the longest.	[reply] [d/l]

I thought $. only resets on a `close` call? meaning the `<>` operator doesn't reset it, since it never closes the filehandles. So the following code will omit the 35th line only for the first file, but not for any other file: `perl -ne 'print unless $. == 35' file1 file2` [download] Is that correct? -- Dan	[reply] [d/l] [select]
