VirtualFS

  • Shell filesystem: /#sh:[user@]machine[:options]/[remote_dir]

Configuration

  • To use vi as standard editor/viewer
First menu OptionsConfiguration...uncheck use internal edIt and Use internal view.
Next, at the end of file .mc/bindings:
default/*
    Open=
    View=view %f
    Edit=%var{EDITOR:vi} %f
  • Edit /etc/mc/mc.keymap* to use C-n for Auto-Complete (instead of Alt-Tab that does not work in graphical environment) (see below)
  • Check complete: show all (so that selection box is shown on first ambiguity)
  • To have common history between mc sub-shell and parent shell: [1]:
alias mc='PROMPT_COMMAND="history -a; history -r" mc; history -r'
  • Add the following to ~/.bash_profile and ~/.profile to Meta-key (Alt) not working and Midnight Commander displays Press any key... after each command when in tmux session [2]:
# This fix meta-key support and stop mc displaying "Press any key..." in tmux session
if [ $TERM = "screen" ]; then
    export TERM=xterm
fi
if [ -n "$TMUX" ]; then
    export COLORTERM=rxvt
fi
Note: A better fix might be to do mc -x instead to force xterm mode. See ticket 2479 and ticket 2978 for more information.


Obsolete configuration (for old version):

  • mc will only save the option ini file if there is a directory ~/.mc in home directory:
mkdir ~/.mc

Some work-arounds / advices:

  • Gnome-Terminal conflictGnome Terminal shortcuts conflict with MC. Disable them in Keyboard shortcuts menu (Terminal menu shortcut key (F10) and Menu Access Keys (A-h).
  • Auto-Complete does not work — The auto-complete shortcut M-Tab (i.e. Alt-Tab) doesn't work in graphical environment because it is used for switching between windows. As a replacement, one can use Esc-Tab, or can define a new shortcut like C-n (as in Vim).
    Old version — This can be done with Options... → Learn Keys...
    Newer version — The learn keys trick does not work anymore. Remove the learn key line from ~/.mc/ini and instead edit all files /etc/mc/mc.keymap* as follows:
For mc version 4.7:
PanelMoveDown = down
...
InputComplete = alt-tab; ctrl-n
...
TreeMoveDown = down
For mc version 4.8 and above:
[panel]
...
MoveDown = down
...
[input]
...
Complete = alt-tab; ctrl-n
...

or via command-line:

sudo sed -ri 's/; ctrl-n//' /etc/mc/mc*.keymap
sudo sed -ri 's/Complete.*/Complete = alt-tab; ctrl-n' /etc/mc/mc*.keymap
  • Lynx motion — This is a nice option to enable in the configuration menu. When enabled, enter a directory with right and exit a directory with left.

Official repository

Besides Ubuntu repository, the official one is here. To add it:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F82FBD49

Add file /etc/apt/sources.list.d:

deb http://ppa.launchpad.net/zyv/ppa/ubuntu lucid main
deb-src http://ppa.launchpad.net/zyv/ppa/ubuntu lucid main

Then upgrade if needed:

sudo apt-get update
sudo apt-get upgrade


Troubleshoot

MC shows "press any key to continue..." when TERM=gnome-256color

Setting TERM is necessary to fix issues in Neovim.

  • Workaround: start mc with mc -x to force xterm mode:
# MC - Force xterm mode if TERM=gnome-256color
[ "$TERM" = "gnome-256color" ] && alias mc='mc -x'
  • Update: we don't change TERM anymore, so this fix is no longer necessary.

Ctrl-Shift-Enter not working in Wayland

This happens in latest Debian (Buster), and is due to Wayland security model [3].

As a fix, we can use Alt-M instead [4]:

sudo sed -ri '/PutCurrentFullSelected/s/=( alt-m;)?/= alt-m;/' /etc/mc/mc.default.keymap
sudo sed -ri '/Mail = alt-m/s/= alt-m/=/;' /etc/mc/mc.default.keymap

Ctrl-Shift-E not working

In recent Gnome, Ctrl-Shift-E is now assigned to emoji input.

To remove [5]:

  • Start ibus-setup
  • Go to Emoji, click ... for emoji, then delete.
