sed error: "parentheses not balanced" - But they are!
I have a list of words, and some of them have parentheses around them like:
" (( hello )) "
I'm trying to remove them with sed, but it says that "parentheses not balanced"
The sed command is:
sed "s/([ ]?\)\)[ ]?)|([ ]?\(\([ ]?)/ /"
... and the exact error is:
sed: 1: "s/([ ]?\)\)[ ]?)|([ ]?\ ...": RE error: parentheses not balanced
You can see I escape all of the literal parentheses. What am I doing wrong?
Thanks.
