I have many images captured from my webcam and their name are:
2021-03-29_06-00
2021-03-29_06-02
2021-03-29_06-04
2021-03-29_06-06
2021-03-29_07-00
2021-03-29_08-00
2021-03-29_09-00
etc..
I want to delete images shooted by night.
I found script to obtain sunrise (and sunset) times, now I have to filter my files and delete.
I start to try with ls command.
If I use:
ls *_{00..06}*.jpg
the result is correct.
By if I insert a variable with the time of sunrise, encounter of problems.
SUNRISE="06"
ls *_{00..$SUNRISE}*.jpg
But the result are:
ls: cannot access '*_{00..06}.jpg': File or directory does not exist
bash
, brace expansion is done BEFORE the variable is evaluated. Maybe this answer will help? – FelixJN Mar 29 '21 at 21:37
