tmux if-shell
Execute the first command if shell-command returns success or the second command otherwise.
Syntax¶
tmux if-shell [-bF] [-t target-pane] shell-command command [command]Alias: if.
Behavior¶
Execute the first command if
shell-command returns success or the second
command otherwise. Before being executed,
shell-command is expanded using the rules specified
in the FORMATS section, including those
relevant to target-pane. With
-b, shell-command is run in
the background.
If -F is given,
shell-command is not executed but considered
success if neither empty nor zero (after formats are expanded).
