Search and replace script
Hi,

Below is the script which will find a particular text and replace with another one in a group of files under a directory /test
Code:
#!/bin/bash
old=$1 --- first input old text
new=$2--- input new text
cd /test --- folder into which files need to be checked
for y in `ls *`;
do sed "s/'$old'/'$new'/g" $y > temp; mv temp $y;
done

I am executing the script as below
Code:
# ./search.sh abc def

But there is not change taking place. Please advice on the script.

It's probably the single quotes in the sed command. The replace is looking for <single-quote>abc<single-quote>

Beware of useless use of ls too.
Code:
#!/bin/bash
old=$1
new=$2
cd /temp
for file in *
do
  sed  "s/$old/$new/g" $file > $file.out
done
