kutipan
cmdhist If set, bash attempts to save all lines of a multiple-line
command in the same history entry. This allows easy re-editing
of multiline commands.
lithist If set, and the cmdhist option is enabled, multi-line commands
are saved to the history with embedded newlines rather than using
semicolon separators where possible.
Mengaktifkan fitur
$ shopt -s cmdhist
$ shopt -s lithist
Menonaktifkan fitur
$ shopt -u cmdhist
$ shopt -u lithist
