Unix Script "File Change"
Hi Guys,
I am looking for a script that will change a certain character of a file name. I have a bunch of files from a location i.e "wf95234red3" and i want to change the file to "wf96234red3" just changing the 6 . What i need is to change lots of these at the same time. All the files have different letters at the end but the first part is the same wf95. Regards Trouble........

A small shell script should do the trick if you only want to change the 5 to a 6 (run this in the same directory as the wf95* files):
Code:
#!/bin/sh for file in `ls wf95*` do echo $file | sed -e 's/wf95\(.*\)/mv "&" wf96\1/' | sh done You might want to test it first by removing the '| sh' - it should output a list of 'mv' commands: Code:
[23:47:22] root@users /root/tmp# ./tmp.sh mv wf95234red3 wf96234red3 Even quicker you could just run the command from the commandline: Code:
ls -1 wf95* | sed -e 's/wf95\(.*\)/mv "&" wf96\1/' | sh again though make sure the command is outputting what it should by removing the |sh first. Last edited by munkfish : August 17th, 2003 at 09:23 AM.

Use the -i switch to edit the file 'in place':
Code:
sed -i -e 's/wf95/wf96/g' wf96* To change every occurrence of 'wf95' with 'wf96' everywhere it occurs on each line.
