Why set the env 'TERM=xterm'

[chenjunnn]

I am using vscode built-in terminal, and when I use this script to create a container, I found the zsh-auto-suggestion is not working properly as the color of the suggestion is wrong:

• Expected:
  

• Actually:
  

Then I found it was caused by the env TERM was set to xterm.
So I remove the export TERM=xterm, then echo $TERM to find that it is xterm-256color originally.
I wonder why the env 'TERM=xterm' would be set and if there should be an option to disable it.

I will do more tests and make sure xterm-256color is available in all distros supported before changing this. Thanks for reporting.

Hi, maybe we can check if this varible has been set, if not set it to xterm.

if [ -z "$TERM" ]; then
  export TERM="xterm"
fi

Then we can pass this env varible during lauching like this

docker run -it --env=TERM=xterm-256color image:tag zsh

The PR #30 should allow the TERM setting to be bypassed.
