in thread perl -pi -e s'/^\s+//'g $file

Actually ARGV::readonly isn't needed with -i.orig (or -pi.orig) because perl does a stat first

$ perl -pe 1 "echo shabba|" shabba $ perl -Tpe 1 "echo shabba|" Insecure $ENV{PATH} while running with -T switch. $ perl -Tpi.orig -e 1 "echo shabba|" Can't open echo shabba|: Invalid argument.

[Lady_Aleena]: ctags?
[shmem]: ctags is a program which (recursively) extracts the symbols from source and stores them in a one-file database. This allows you to query the locations where these symbols (e.g. a subroutine name) are used anywhere in the source code tree...
[shmem]: ...from inside the editor.
[shmem]: apt-get install exuberant-ctags
[Lady_Aleena]: I think I heard vim has a big learning curve.
[shmem]: then in the root of your source tree run: ctags -R
[shmem]: you get a file named tags where all symbols and the places where they are used are listed
[Lady_Aleena]: geany may not support that.
[shmem]: I see that there is a plugin geany-plugin- codenav
