If you want to do a pattern-match against a string, then extract a part of it, a common way is to use sed. For instance, to extract a word and remove spaces before and after it: $ STRING=' abc def ' $ WORD="$( <<<$STRING sed -e 's/^ *\([^ ]*\) *$/\1/' )" $ echo "$WORD" It is common to use common Unix utilities to modify data items within shell scripts.
