exec-if-not-env - Execute command if certain environment variable is false
This document describes version 0.02 of exec-if-not-env (from Perl distribution App-ExecIf), released on 2017-07-04.
% exec-if-not-env RUN somecmd --cmdopt ...
The above will run
somecmd only if
RUN environment variable is not defined or false (with the notion of false follows Perl, i.e undefined,
0 are false).
99 on command-line options error.
Otherwise exit code from command is returned.
Yes, you can also do something like this in bash:
if [[ "$SOMEENV" == 1 ]]; then false; else somecmd --cmdopt ...; fi
But using this utility is simpler and more portable.
