How to Expand String Function in Launcher Command?

johnywhy · 2019-10-14 19:06:17

run at command line, this works.

xfce4-screenshooter -f -s "/mnt/Docs/Pictures/Screenshots/shot-$(date +%Y%m%d%H%M).png" -d 10

I get an output file like:
shot-201910141202.png

Trying to run from a launcher, the date isn't expanding. I get:
shot-$(date +).png

I tried preceding with exec, preceding each quote with escape \, and wrapping the whole thing in single-quotes. Nothing works-- date won't expand.

How to execute this from a launcher?

The launcher command interpreter is pretty basic and can't handle special characters well. It is best to put commands like these in a shell script and execute that shell script from the launcher.

any workaround, besides a script?

thx

Run it with the shell

sh -c 'command here'

Thx @Misko_2083, but didn't seem to work. I got
shot-.png

so the whole date portion was removed. I didn't get the codes or the expansion. Here's what i put into the launcher:

sh -c 'xfce4-screenshooter -f -s "/mnt/Docs/Pictures/Screenshots/shot-$(date +%Y%m%d%H%M).png" -d 10'

Maybe scrot is better.
install scrot and try:

sh -c "scrot 'shot-%Y%m%d%H%M.png' -e 'mv $f /mnt/Docs/Pictures/Screenshots/' -d 10"

After making the screenshot it will be moved to /mnt/Docs/Pictures/Screenshots/.
