Hello.
If we want xargs stop on command fail we need to do the next complex construct
with sh:
xargs -IX -n1 sh -c "cp -f X $IMGDIR_DST/X || exit 255"
instead of simply:
xargs -F -IX -n1 cp -f X $IMGDIR_DST/X
(imagine the -F turns on stop on command fail). This is simpler and less error
prone.
Thus, we can do in our scripts:
find . -type f | xargs -F -IX -n1 cp -f X $IMGDIR_DST/X || exit 1
Instead of more complex and error prone:
find . -type f | xargs -IX -n1 sh -c "cp -f X $IMGDIR_DST/X || exit 255" ||
exit 1
