256color $TERM With st, tmux and fish
It can be difficult to get your terminal colors working correctly between your terminal emulator, tmux and your shell.
First, check the TERM variable in the fish shell:
$ echo $TERM
Ideally, it should be either
xterm-256color or something like that.
You shouldn't set the TERM variable with fish.
The Arch Wiki for st explains that you can set the terminal type with st.
static char *termname = "st-256color";
I start my terminal session with the i3 window manager, so I have the following binding in my i3 config file:
bindsym $mod+Return exec sterminal -n "st-256color"
Now, when I run this in fish:
$ echo $TERM > st-256color
Now, add the following to your
set -ga terminal-overrides ",st-256color" set -g default-terminal "tmux-256color"
This sets the TERM variable for tmux to
tmux-256color and leaves everything outside of tmux on
Even with the above solution, I got tons of errors with NeoVim.
The easiest solution is to fall back to the bash shell as your default shell and to set fish as interactive shell only.
Add this to your
# Terminal to sterminal export TERMINAL="sterminal" # Fish Shell exec fish
Make sure that the Linux user uses bash as default shell.
