Midnight Commander

mc or Midnight Commander is a powerful file manager working in a shell terminal.

Links

• Cool review of mc in action
• The GNOME Commander, a X alternative of mc under Gnome
• Krusader, a X alternative of mc under KDE

VirtualFS

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

Configuration

• To use vi as standard editor/viewer

First menu Options → Configuration... → 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

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.

Keyboard shortcuts

Frequently used keyboard shortcuts (custom shortcuts defined with Learn Keys... are underlined):

General: C-k C-l F10 C-o C-xd C-r C-o M-* A-? C-xq C-xc C-xo C-xs Down Up Exit Midnight Commander open sub-shell (at current directory) Compare directories Rescan (refresh panel contents) Hide panels Reverse selection Find file Quick view / Quit quick view Change file and directory rights - chmod Change file and directory owner - chown Make symlink Shell Command Line A-Enter C-S-Enter M-Tab or C-n C-x t C-x C-t C-x p C-x C-p A-p A-n A-h Paste current selection Paste fullpath current selection Auto-complete Paste tagged files Paste tagged files (other panel) Paste current path Paste current path (other panel) Previous command in history Next command in history Command history

Some work-arounds / advices:

• Gnome-Terminal conflict — Gnome 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.
