I want to take a screenshot with
import, and save it into a file whose name is current time.
Here is what I've tried:
sunqingyao:~$ date '+screenshot-%y%m%d-%H%M%S.png' screenshot-170716-173336.png # OK sunqingyao:~$ import screenshot-170716-173336.png sunqingyao:~$ ls -l screenshot-170716-173336.png -rw-rw-r-- 1 sunqingyao sunqingyao 250556 Jul 16 17:35 screenshot-170716-173336.png # OK sunqingyao:~$ date '+screenshot-%y%m%d-%H%M%S.png' | import import: missing an image filename `import' @ error/import.c/ImportImageCommand/1293. # Not OK
For some reason, I want this command to be a one-liner.
Actually I'm trying to bind a key to screenshot taking with i3. Here is the relevant part of my
# Take a screenshot upon pressing $mod+x (select an area) # https://i3wm.org/docs/userguide.html#keybindings bindsym --release $mod+x exec --no-startup-id date '+screenshot-%y%m%d-%H%M%S.png' | import
Seems that I can only bind a key to a command that can fit in only one line, which is why a one-liner is required.
