How about:
Code:
CMD="perl -pi -e 's/PASSWORD=.*?,/"$password",/' abc.txt"
eval "$CMD"

It should also work if you replace the single quotes with double quotes:
perl -pi -e "s/PASSWORD=,/$password," abc.txt

What is your program?

Parameters are stored in the argv array - and it is trivial to add something like "password=value" on the command line.

Actually, I have one file which contain connector with parameter,and want to replace only activate connector PASSWORD with this format NEW_PASSWORD=$password, password value accept by the user. for example below:


echo "Enter New Password:="
read password


perl -pi -e
's/PASSWORD=.*?,/$password,/' abc.txt


This is may abc.txt:-
# Activate connector
3[USER-ID=abacsd,PASSWORD=1234568,member-id=psudfsfd, etc..]

# DeActivate connector
;8[USER-ID=fdsdfgs,PASSWORD=45646224,member-id=psudfsfd, etc..]


Updated abc.txt
# Activate connector
3[USER-ID=abacsd,NEW_PASSWORD=1545644,member-id=psudfsfd, etc..]

# DeActivate connector
;8[USER-ID=fdsdfgs,PASSWORD=45646245,member-id=psudfsfd, etc..]

What should i do?
