[SOLVED] Short key to exec a command

daunbailo · 2021-02-15 19:28:35

Hi there,
in the Setting Shortcut Keyboard I've created a new one:
xfce4-terminal -x 'ffmpeg -f x11grab -framerate 25 -i :0.0 /home/myuser/output.mp4' associated to CTRL+1 key.

But it doesn't work: every time I type CTRL+1 an empty terminal is shown with this message: "Failed to execute child process [see command above...]. Failed to excecve: no such file or directory"

Can you help me please?
Thank you

Don't use quotes with "-x". If you do, it assumes the whole string is the command. Try:

xfce4-terminal -x ffmpeg -f x11grab -framerate 25 -i :0.0 /home/myuser/output.mp4

...or use "-e" with the quotes.

seems ok.
And if I want a file with date in the name? this doesn't work:

/home/myuser/`date +%d-%m-%Y_%H-%M-%S`_output.mp4

The built-in interpreter is not a full shell interpreter. Best to enclose complex substitutions in a shell. Something like:

xfce4-terminal -x bash -c 'ffmpeg -f x11grab -framerate 25 -i :0.0 /home/myuser/`date +%d-%m-%Y_%H-%M-%S`_output.mp4'
