Hi,

Didn't understand the second part of the question i.e. to search from the beginning or end. Can you please demonstrate with an example?

Does the below code help?

Code:
#!/usr/bin/sh

echo "Enter the first string: \c"
read t
echo "Enter the search string to strip: \c"
read u

echo $t | sed "s/\(.*\)\($u\)\(.*\)/\1\3/g"
exit;
