In one of my config [~/.tmux.conf] there is a line :
set -g default-terminal "screen-256color"
set -s escape-time 10
I think it sets global variables of my system. But I am not sure.. I searched for it on the web ... & even the man pages doesn't give me information about -g option when in bash I did help set and there are not information about -g option and -s option..
How do I find out what these command does by reading man pages...
set is an alias to tmux set-option
Commands which set options are as follows:
set-option [-agsuw] [-t target-session | target-window] option value
(alias: set) Set a window option with -w (equivalent to the set-window-option command), a server option with -s, otherwise a session option.
If -g is specified, the global session or window option is set. With -a, and if the option expects a string, value is appended to the existing setting. The -u flag unsets an option, so a session inherits the option from the global options. It is not possible to unset a global option.
It's not bash conf, it's tmux confs, so you should look for information about this option in tmux help.
Quick searching gave me that:
If -g is used, the change is made in the global environment; otherwise, it is applied to the session environment for target-session.
Those are tmux commands. The tmux config file is read and interpreted by tmux. The shell language does not apply.
You're looking for the tmux man page, which describes the -s and -g flags as well as the meaning of the options (as they are referred in the tmux man page) such as default-terminal and escape-time.
Note that the set command does not appear to be documented on the man page on GNU/Linux, but it is an alias of set-option.
