[8] HISTIGNORE A list of patterns, separated by colons (:), used to decide which command lines to save in the history list. Patterns are considered to start at the beginning of the command line and must fully specify the line, i.e., no wildcard (*) is implicitly appended. The patterns are checked against the line after HISTCONTROL is applied. 208
