Re^3: Deleting first and last lines of a text file

This deletes the fist line and the last 2 lines of input.txt and keeps a copy of the old version in input.txt.old.

perl -i.old -ne 'my $l = <>; print($l), next if $.==2; print "$_$l" un
+less eof' input.txt

Note that this is a one-liner to be run as is from the command-line (adjust your input file-name).

It is taking so much time and not exiting when I run it as a one liner. `perl -i.old -ne 'my $l = <>; print($l), next if $.==2; print "$_$l" un +less eof' /home/file_20140319.txt` [download]	[reply] [d/l]
