`nnn` can invoke custom scripts with the currently selected file name as argument 1.
Export the path to the custom executable script:
Export the absolute path to the directory with your scripts or a single script:
export NNN_SCRIPT=/usr/local/bin/nscript
export NNN_SCRIPT=/home/user/scripts
OR
export NNN_SCRIPT=/usr/local/bin/nscript.sh
Press <kbd>R</kbd> to run the script in the current directory.
It's possible to run multiple scripts with `nnn` as long as the scripts are in the same location and share the same prefix. To enable multiple scripts,
export NNN_MULTISCRIPT=1
With the example of `NNN_SCRIPT` above, some more scripts could be:
/usr/local/bin/nscript1
/usr/local/bin/nscript2
/usr/local/bin/nscriptcustom1
/usr/local/bin/nscriptcustom2
and so on...
Type the correct suffix when prompted on pressing the keybind <kbd>R</kbd>. To use the base script (`NNN_SCRIPT`), just press <kbd>Enter</kbd>.
Press <kbd>R</kbd> to run the script in the current directory. You can also use this key to cancel choosing a script from the script directory.
