When I run the :sh command I see the following characters

enter image description here

If it is relevant, my default shell is zsh and it runs oh-my-zsh also
Thanks

  • Can you confirm the problem doesn't come from your vimrc? – statox Mar 5 at 11:09
  • using the default vimrc gives the same wired characters – jagjordi Mar 5 at 11:28

    01;32m feels like color codes to me. and those box icons are glyphs not supported by your font. Have you recently changed your configuration? As in moved to a new font/terminal emulator/distro/copied someone's bashrc? – klaus Mar 5 at 12:32
  • I recently discovered the sh command and Is always been like this. bashrc is made by my, running an empty bashrc results in the same issue – jagjordi Mar 5 at 12:35
  • Whats the Vim version? (See Help->About) – Ralf Mar 6 at 5:55

You are doing this in GVim and this only provides a terminal with limited capabilities. The command echo $TERM returns "dumb". Might be your zsh /oh-my-zsh setup can't handle this.

It works for me (with bash) as my bash setups checks for terminal capabilities before configuring a colored PS1 or configuring colored output for ls or grep.

Vim 8.0.1609 added the guioption !, see :help 'go-!'. This provides a better terminal:

:set guioptions+=!

Then the "terminal" started by :sh supports colors.(tested with Vim 8.1.996 on Ubuntu: echo $TERM returns "xterm").

If you have Vim 8.0.747+, or better 8.1.x, you should use :terminal to start a terminal window inside GVim. See :help terminal.

If you are on an older version of Vim, you need to change your zsh setup to work properly on a dumb terminal. Google something like "zsh dumb terminal" or "oh-my-zsh dumb terminal".

  • I tried adding ! to guioptions but the problem persists – jagjordi Mar 5 at 23:16
  • @jagjordi Updated, added some version information. – Ralf Mar 6 at 6:37
  • @jagjordi try to set shell=/bin/bash and then run shell :sh – Alex Kroll Mar 6 at 6:40
  • @AlexKroll Do you want to write that in a own answer, or should I integrate it into my answer? – Ralf Mar 6 at 10:20
  • I am not sure. Your solution solves the issue of getting the wired characters to disappear, but maybe I should post another answer asking how to get zsh to work with :sh – jagjordi Mar 6 at 14:36
