Hi Corona688, thank you for your prompt reply.

I have tested and tried to edit my script with yout advice.. but still unable to get the value of PWD to replace my copy of shell script.

I have 2 shell script, a.sh and b.sh.

a.sh will make a copy of b.sh at /etc/init.d and will replace the "$PWD" keyword in the copy of b.sh.

Below is the edited code for my scripts:

a.sh

Code:
current_dir="$PWD"
echo $current_dir

cp $current_dir/b.sh /etc/init.d/copyOfb.sh
sed -i 's/$PWD/"$current_dir"/g' /etc/init.d/copyOfb.sh

b.sh
Code:
current_dir="$PWD"
echo $current_dir

when i execute the a.sh... the keyword PWD in copy of b.sh is replaced with the string "$current_dir"
and eventually i have this
current_dir=""$current_dir""
in my copyOf b.sh....


I tried to manipulate the quotes.. but still unable to get the thing right...

please advise again...
