Re: bulk rename pod1 pod2 needed
I think the following script will for for your pattern.
-- CUT HERE ---
#!/bin/bash
# To rename ccna.pod1.pc1.ext is renamed to ccna.pod2.pc1.ext
for file in $(ls ccna*ext | sort -rn -k 1.9)
do
let ix=$(echo $file | sed -e 's/.*pod//' -e 's/.pc..ext//')
let iy=$ix+1
newfile=$(echo $file | sed s/pod$ix/pod$iy/)
if [ -e $newfile ] ; then
# Shouldn't get here
echo Rename error of $newfile
continue
fi
mv $file $newfile
done
CUT HERE

That would move them to pod# names.

Re: bulk rename pod1 pod2 needed
That is what my script does. The sort -rn -k 1.9 says, sort reverse numeric with key 1 character position 9. I also check to make sure that another file is not dropped in there during processing of the script.

From: Stephen P Rufle stephen.p.ru...@cox.net Is there a way to single step bash script to inspect what is going on? When I need copious debugging output from a bash script, I put set -x at the top of the file. When I need to check the syntax for a script, I do sh -n file.sh.

RE: bulk rename pod1 pod2 needed
What hasn't been answered is if this is open ended ? Are you going to keep counting forever, thus keeping on to 25, 26, 27. Or can we cut it off at a particular number ? 24 ? If we can cut it off then this simple solution would work cd /the_directory mv ccna.pod23.pc1.ext to ccna.pod24.pc1.ext mv ccna.pod22.pc1.ext to ccna.pod23.pc1.ext mv ccna.pod21.pc1.ext to ccna.pod22.pc1.ext . . mv ccna.pod1.pc1.ext to ccna.pod2.pc1.ext touch ccna.pod1.pcl.ext If these are log files of some kind, you may want to look at the command logrotate which is designed for such things. Your initial message just asks how to rename the files, but in order to come up with the correct solution you need to explain more on what you are trying to accomplish. Otherwise you get lots of different answers, all very valid, but accomplishing different things. For instance, if you move 1 to 2, then 2 to 3, and 3 to 4. You end up with 1 file that was originally 1, and could have been done 1 to 4. Even after we know what you are trying to accomplish, the great thing is in linux there are many ways to do it. -Original Message- From: plug-discuss-boun...@lists.plug.phoenix.az.us [mailto:plug-discuss-boun...@lists.plug.phoenix.az.us] On Behalf Of Alex Dean Sent: Tuesday, February 17, 2009 12:47 PM To: Main PLUG discussion list Subject: Re: bulk rename pod1 pod2 needed On Feb 17, 2009, at 11:38 AM, Dennis Kibbe wrote: Actually, if the original specification is co= rrect, probably none of the solutions proposed is likely to work.nbsp; It = appears that the target name for the first rename is the same as the source= for the second.nbsp; If this were true one would have to ensure that rena= me or move operations were done in an order to avoid attempts to overwrite = existing names.

A quick Perl solution.
#!/usr/bin/perl -w
use strict;
my $indir = '/path-to/the-files';
opendir(DIRECTORY, $indir) || die Could not open $indir - $!\n;
my @files = grep /\.ext$/, readdir(DIRECTORY);
closedir(DIRECTORY);
@files = reverse(sort(@files));
foreach my $oldfilename (@files) {
if ($oldfilename =~ /^ccna.pod(\d+)/) {
my $sequence = $1 + 1;
my $newfilename = 'ccna.pod' . $sequence .'.pc1.ext';
rename($oldfilename, $newfilename) || die Could not rename
$oldfilename to $newfilename - $!\n;
}
}

RE: bulk rename pod1 pod2 needed
This will increment the second field in the file for each file in the directory
named *.ext.
The last digit before dot will increment by 1; yet if it is 9 it should become
0.
[Caveat - untested...(use carefully)]:
ls *.ext |
awk -F. '{s=substr($2,length($2))
s++;s=s==10?0:s
printf(mv %s %s%s.%s\n, $0, substr($2,1,length($2)-1), s, $3)}
' | sh
