Syntax error : "(" unexpected — with !(*.sh) in bash script [duplicate]
25 janvier 2023, par Jmv JmvI want to run a sh file :



#!/bin/bash
for f in !(*.sh); do
 ffmpeg -i "$f" -vf yadif=0:-1 -threads 0 -c:v libx264 -pix_fmt yuv420p \
 -r 29.97 -b:v 3000k -s 1280x720 -preset:v slow -profile:v Main \
 -level 3.1 -bf 2 -movflags faststart /mnt/media/out-mp4/"${f%.mxf}.mp4"
 rm $f
done




However, I get the following error :



2: task1.sh: Syntax error: "(" unexpected




If I try directly on the command line it works perfectly.





the path and permissions are already reviewed





Any idea what might be happening ?
