Re: how to delete part of the line?

perl -ple's/^line\d+=//' infile > outfile
[download]

Use double quotes in Windows.

Update: Oops, I forgot about the slashes. That should be

perl -nle's/^line\d+=//; push @l,$_; END { $,=q{/}; print @l }' infile
+ > outfile
[download]

Not nearly as nice a one-liner :(

Than maybe two simple one-liners? `perl -ple's/^line\d+=//' infile \| perl -p0e 's!\n!/!g' > outfile` [download] or `perl -ple's/^line\d+=//' infile \| perl -p0e 's!\s+$!! ; s!\n!/!g' > ou +tfile` [download] if end of the output has any meaning. Hmm, seems there is no beauty, too.	[reply] [d/l] [select]

No good. Those replace the trailing newline with a "/". If that was desirable, the following would suffice: `perl -pl57e"s/^line\d+=//" infile > outfile` [download]	[reply] [d/l]
