Replacing line in multiple file at a time

talat · 02-14-2008, 02:46 AM

Hi Guys,

Consider the following scenario.

I have a folder by the name clients. In this folder i have around 100 files. In each file there is line which has following phrase as common.

Workdir:/var/www/html/

Example in file for UBL customer this line is

Workdir:/var/www/html/ubl

For customer HMC this line is

Workdir:/var/www/html/hmc

Now i need to replace only the Workdir:/var/www/html to Workdir:/var/www/html/london in all the files of this folder.

So that for UBL customer it becomes

Workdir:/var/www/html/london/ubl

Any clue how can i do it with script.

Regards

Guys i have done it with following script.

First i get list of all files in a file via

#ls > lisofallfile
Then i run this script

#/bin/sh

while read line; do
/bin/sed 's/\/var\/www\/html/\/var\/www\/html\/khi/g' < $line > tempfile
cat tempfile > $line
done < listofallfiles

Use sed s/oldpattern/newpattern

Code:

sed -i 's/pattern/replacement/g' *

this will modify the files in place. If you're just doing an ls, then '*' should work fine.
