How can I open files whose name contains sharps / hashes #
from the Cinnamon Nemo right-click context menu?
A Nemo action e.g. /usr/share/nemo/actions/unzap.nemo_action
which contains the line Exec=unzap "%F" will open most files,
but fail to escape filenames which contain a #.
Use Exec=<open.py "unzap" %F> instead of Exec=unzap "%F" in the unzap.nemo_action.
The unescape the backslashes in open.py as follows:
#! /usr/bin/python3 -OOt
import sys
import subprocess
command = sys.argv[1]
filename = sys.argv[2].replace("\ "," ")
subprocess.run([command, filename])
