Here is a renaming program adapted from the one in the Perl Cookbook,
Recipe 9.9:
#!/usr/bin/perl
#
# rename
#
# perl script to rename files
#
# Usage:
#
# rename perlexpr [files]
#
($op = shift) ||
die
"Usage: rename perlexpr [filenames]
where perlexpr is any perl expression that modifies \$\_:
's/old/new/'
'\$\_ .= \".ext\"'
'tr[A-Z][a-z]'\n";
You should use a here doc so you don't have to backslash everything:
my $op = shift or die <<'USAGE';
Usage: rename perlexpr [filenames]
where perlexpr is any perl expression that modifies $_:
's/old/new/'
'$_ .= ".ext"'
'tr/A-Z/a-z/'
USAGE
if( !@ARGV ) {
@ARGV = <STDIN>;
chop( @ARGV );
You should use chomp instaed of chop:
chomp( @ARGV = <STDIN> );
}
for( @ARGV ) {
$was = $_;
eval $op;
die $@ if $@;
rename($was,$_) unless $was eq $_;
}
That looks a lot like Larry's rename script which is distributed with
some versions of Linux.
