From man bash : [[ expression ]] Evaluate the conditional expression expression and return a sta‐ tus of zero (true) or non-zero (false). Expressions are composed of the primaries described below under CONDITIONAL EXPRESSIONS. The words between the [[ and ]] do not undergo word splitting and pathname expansion. The shell performs tilde expansion, parame‐ ter and variable expansion, arithmetic expansion, command substi‐ tution, process substitution, and quote removal on those...
