Find and replace permanently
i have a few scripts in which i need to find string"ali1@abcd.com" and replace it with "ali@abcd.com"
i used 2 below commands but none of them is permanently replacing the old string in the script s.sh

Code:
perl -pi -e 's/ali1@abcd.com/ali@abcd.com/g' s.sh

sed 's/ali1@abcd.com/ali@abcd.com/g' s.sh

Please help me in this

Try this
for line in `cat /dir/s.sh`
do
echo $line >file.sh
sed 's/ali1@abcd.com/ali@abcd.com/g' file.sh >>output.sh
done
mv output.sh s.sh

or

sed 's/ali1@abcd.com/ali@abcd.com/g' s.sh>s1.sh
mv s1.sh s.sh

Try escaping the @ symbols. The dots should be escaped also, otherwise they actually stand for "any single character".

perl -pi -e 's/ali1\@abcd\.com/ali\@abcd\.com/g' s.sh

i cannot do the rename part as most of the scripts after renaming i need to change the permission.

As i m working in production enviroment so i just want the command which can just overwrite the scripts rahther than renaming it.

Check if this works for you..

Code:
sed -i -e's/ali1@abcd.com/ali@abcd.com/g;' s.sh

No. it's telling the below error:
Code:
sed -i -e's/ali1@abcd.com/ali@abcd.com/g;' s.sh

sed: illegal option -- i
Usage:  sed [-n] Script [File ...]
        sed [-n] [-e Script] ... [-f Script_file] ... [File ...]

Hi Ali ,
Though the above version is working fine for me you can try
sed -e's/SEARCH/REPLACE/g;' asd_dup.txt
