Copying files from command line to clipboard

In a GUI file manager it is possible to select a few files, press Ctrl-C (which supposedly copies come info about the files to clipboard), then navigate to another folder and press Ctrl-V, which will then copy the files into that directory.

As an experiment, after copying files in the file manager, it is possible to switch to a text editor – pressing Ctrl-V there pastes a list of absolute filenames. The reverse process (copying a list of files from a text editor and pasting them to a file manager) does not work, which is supposedly due to different target atoms

The goal of the exercise is to be able to copy some files from command line, for example

find ${PWD} -name "*.txt" | xclip <magic parameters>

then switch to a file manager and copy them all to a directory using File->Paste.

So, the question is: What parameters of xclip (or other program) do I need to specify so file manager recognizes the selection as a list of files and enables its Paste menu item?

Alternatively, is there a low-level tool which would allow to inspect the contents of X selection and see what data it currently contains?

why not just make find do it for you?

find ${PWD} -name "*.txt" -exec cp {} /full/path ; && gnome-open /full/path &

EDIT: from what I understand from man xclip: it handles text only, not files or directories.

Yes, basically, you’d need to offer the CLIPBOARD selection either as

  • text/uri-list with the content being

    /path/to/file1
    /path/to/file2
    
  • application/x-kde-cutselection or x-special/gnome-copied-files with content copynfile://$path1nfile://$path2 or cutnfile://$path1nfile://$path2...

With xclip you can achieve this with something like

find "$PWD" -name "*.pdf"| xclip -i -selection clipboard -t text/uri-list

I’ve also found this loliclip command that looked promising, but though I could retrieve the values, I wasn’t able to store them and have them retrieved from loliclip by pcmanfm successfully.

You also should be able to implement it in a few lines of perl-tk.

Based on these answers I wrote a filetoclip Python script, which copies to the clipboard the files specified on the command line.

Essentially, all that’s needed is to absolutize them and percent-encode "strange" characters before copying to the clipboard. The actual clipboard operation is delegated to xclip, as working with clipboard straight from Python is more painful than expected.

#!/usr/bin/env python3
import os.path
import sys
from urllib.parse import quote
from subprocess import run
out = [os.fsencode('file://' + quote(os.path.abspath(x))) for x in sys.argv[1:]]
run(['xclip', '-i', '-selection', 'clipboard', '-t', 'text/uri-list'],
    input=b'n'.join(out), check=True)
