Problem	Solution	Example	Reference	Recommended
[[ $(echo $var \| grep -ic "pattern") -eq 0 ]] & You could also go for "-eq 1" - does contain: [[ $(echo $var \| grep -ic "pattern") -eq 1 ]] & Or "-ne 0" for same, etc. [[ $(echo $var \| grep -ic "pattern") -ne 0 ]] & Plus you could use \|\| for "or" either in place of "&&" or after this block - same as if .. then "positive" else "negative" fi. [[ $(echo $var \| grep -ic "pattern") -eq 0 ]] \|\| { echo "var does contain pattern" }
