Unix cut operation

If you want the literal text "undergrad" in the brackets, this should work:

cut -d "(" -f 2 <text> | cut -d ")" -f 1

or equivalently

echo <text> | cut -d "(" -f 2 | cut -d ")" -f 1

linux shell unix

If this string comes from id, then you can just call id -gn instead.

linux shell unix

var1=$(cmd |sed 's/.*(\([^)]*\))/\1/')
