I always figured, if you're going to do it, do it right:

#!/usr/bin/perl use strict; my $pattern = shift @ARGV; my ($src, $dest) = ($pattern =~ m/^s(.)([^\1]*)\1([^\1]*)\1$/) or die "1st arg not s/// construct (or construct too complicated)" +; my %to_rename; for my $f (@ARGV) { (! -e $f) && die "$f does not exist; $!"; my $n = $f; $n =~ s/$src/$dest/; ( -e $n or defined $to_rename{$n}) && die "$f would be renamed to $n; clobber detected"; $to_rename{$n} = $f; } while (my ($n, $f) = each %to_rename) { rename $f, $n or warn "Cannot rename $f to $n; $!"; }

OK, I can see bad style there, but it works. I wrote it some time ago...

I called the script ~mv, and it is called as ~mv s/\.old$/.new/ *.old

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
