如何使用 shell 命令运行 tmux

Question

I want to run tmux with shell command in it

I try: tmux new-session -d -s foo 'echo intmux' ( I want to use this later in bash script)

But it doesn't works. I expect that:

1) Tmux open new window ( like tmux new )

2) command echo intmux will be called

Answer 1

1) Tmux open new window ( like tmux new )

You will not see a new session, because you create it using -d (detached) flag.

What you want (execute a command and leave a shell open) can be easily achieved with:

tmux new -s foo 'echo intmux; $SHELL'

Another tricky option bound to specific (bash) shell:

tmux new-session -s foo 'bash --rcfile <(echo ". ~/.bashrc; echo intmux")'

This allows to preserve default behavior (reading . ~/.bashrc ) and pass your arbitrary command.

Answer 2

You can run

tmux new-session '-s foo' \; neww '-t 2 -n echo' mc

But that spawns another window in the new session running your command so possibly you want to close the first window

tmux new-session '-s foo' \; neww '-n echo' mc \; kill-window '-t 1'
