when I use win7, I can rename files like this:
C:\>rename *.bak *.txt
how to do this in linux?
------------------------
kent$mv *.bak *.txt
it does not work.
Sorry I misread your question. Bash script would be easiest but for fun and games I wrote a poopy perl script for practice.
Code:
#!/usr/bin/perl
use strict;
use warnings;
print "Directory Path: ";
my $dir_path=<>;
print "Old extention: ";
my $oldext=<>;
print "New Extenstion: ";
my $newext=<>;
chomp ($dir_path, $oldext, $newext);
my $dir;
my @files;
opendir $dir,$dir_path || die "could not open $dir_path $!\n";
while (readdir $dir){
if ($_ =~ m/$oldext$/ and ! -d "$dir_path/$_"){
push @files, $_;
}
}
closedir $dir;
for (@files){
my $newname = (split(/\./,$_))[0].$newext;
unless (rename "$dir_path/$_", "$dir_path/$newname"){
warn "$_ File could not be renamed \"$!\"\n";
}
}
Please try doing a forum search before you post common questions like this. There must be hundreds of previous threads discussing how to bulk-rename files.

Maybe it's worth to mention that there are two versions of the rename command. The one mentioned here is usually available on RPM based systems and come from the util-linux-ng package. The syntax is
Code:
rename from to [files]
where from and two are the matching and replacement strings respectively. The other one is usually available on DEB based systems and it is a perl script that uses regular expressions and sed-like commands to perform its task:
