#### copy file paths when X is missing
A very common scenario on headless remote servers connected via SSH. As the clipboard is missing, `nnn` copies the path names to the tmp file `$HOME/.nnncp`.
A very common scenario on headless remote servers connected via SSH. As the clipboard is missing, `nnn` copies the path names to the tmp file `DIR/.nnncp`, where `DIR` (by priority) is:
$HOME or,
$TMPDIR or,
/tmp
`nnn` needs to know X is unavailable:
export NNN_NO_X=1
Use <kbd>^Y</kbd> and/or <kbd>^K</kbd> to copy file paths as usual. To use the copied paths from the cmdline, use command substitution:
To see the path to the copy file, run `nnn`, press `?` and look up `NNN_NO_X`.
Use <kbd>^Y</kbd> and/or <kbd>^K</kbd> to copy file paths as usual. To use the copied paths from the cmdline, use command substitution. For example, if `DIR` above is `/home/user`:
# bash/zsh
ls -ltr `cat /home/user/.nnncp`
