this works with full path, but not if using a var for dir var

barebox@BPI R2PRO:/ i=0;for f in /mnt/sd.1/extlinux/Image*; do basename $f b; echo "$i:$b";let i++; done
0:Image_5.16
1:Image_5.16-next.gz
2:Image_5.16.gz
3:Image_5.16.gz.bak
4:Image_5.16_q64
5:Image_bpi
barebox@BPI R2PRO:/ imgdir=/mnt/sd.1/extlinux/
barebox@BPI R2PRO:/ i=0;for f in $imgdir/Image*; do basename $f b; echo "$i:$b";let i++; done

basename - strip directory and suffix from filenames

Usage: basename PATH VAR

Remove directory part from the PATH and store result into variable VAR.

0:Image_bpi
barebox@BPI R2PRO:/

any idea how to get it working with variable path?

i can do a cd before and drop the basename

cd $imgdir
for f in Image*; do echo $f;done
Image_5.16
Image_5.16-next.gz
Image_5.16.gz
Image_5.16.gz.bak
Image_5.16_q64
Image_bpi


but then i need to restore the path again (something like prevdir=$(pwd);cd $prevdir) if script fails
