Re^2: multiple file operations using perl one-liners

-n + chomp can be replaced with -nl.

That should be /\t/, I think? -a would be better than split

du -b */*/old.zip | perl -F\\t -lane'system zip => "-d", $F[1], "*exe*
+"'
[download]

Or shorter and simpler yet:

du -b */*/old.zip | perl -ne'system zip => "-d", /\t(.*)/, "*exe*"'
[download]

My earlier comment on error checking still applies.

-n + chomp can be replaced with -nl Thanks - quite useful to know. Gotta re-read the perlrun-manpage.	[reply]

Is there any advantage to this variant? It's longer and buggy (missing chomp). It's also less clear due the weird use of `=>` to separate two of three arguments, especially when it's also used to associate the arguments to the command. Either way, I just realised `du` is useless. `perl -e'system zip => "-d", $_, "exe" for @ARGV' //old.zip` [download]	[reply] [d/l] [select]
