# Linux `nnn` Terminal File Manager
Install via `apt` on Debian.
To configure `cd` on exit (via Ctrl+G) you need to add a function to your profile and start `nnn` using that function. See here for more info: https://github.com/jarun/nnn/wiki/Basic-use-cases#configure-cd-on-quit
For `zsh` it's:
```sh
n ()
{
# Block nesting of nnn in subshells
if [[ "${NNNLVL:-0}" -ge 1 ]]; then
echo "nnn is already running"
return
fi
# The behaviour is set to cd on quit (nnn checks if NNN_TMPFILE is set)
# If NNN_TMPFILE is set to a custom path, it must be exported for nnn to
# see. To cd on quit only on ^G, remove the "export" and make sure not to
# use a custom path, i.e. set NNN_TMPFILE *exactly* as follows:
# NNN_TMPFILE="${XDG_CONFIG_HOME:-$HOME/.config}/nnn/.lastd"
export NNN_TMPFILE="${XDG_CONFIG_HOME:-$HOME/.config}/nnn/.lastd"
# Unmask ^Q (, ^V etc.) (if required, see `stty -a`) to Quit nnn
# stty start undef
# stty stop undef
# stty lwrap undef
# stty lnext undef
# The backslash allows one to alias n to nnn if desired without making an
# infinitely recursive alias
\nnn "$@"
if [ -f "$NNN_TMPFILE" ]; then
. "$NNN_TMPFILE"
rm -f "$NNN_TMPFILE" > /dev/null
fi
}
```
