You don't need parentheses around it. The parentheses force the commands to run in a subshell (fork()), so it just slows things down. > if [[ "true" = "true" ]] && [[ "${h:0:1}" = "/" ]]; then echo slash; fi This is fine, but also note that you can put && inside [[ if you wish: [[ "true" = "true" && "${h:0:1}" = "/" ]] Or you can use pattern matching: [[ "true" = "true" && $h = /* ]]
