I suspect that the above assumes all files reside in the same directory. Let
us say that all 3 lines were saved under a file named move_jfif.sh. You
could then use global.sh (see below)
=========
global.sh
=========
# global - execute command in all subdirectories
exec 3<&0 # save standard input
find . -type d -print | # print all directory names
while read dirname
do
(cd $dirname
exec 0<&3 # restore standard input
"$@" # run command
)
done
exec 3<&- # close file descriptor
========
Then make the call:
/home/user/FULL_PATH_IS_IMPORTANT_AS_YOU_CHANGE_LOCATIONS/global.sh
/home/user/YOUT_PATH/move_jfif.sh
I guess this would cover more complex circumstances. By no means do I
criticise David's advice, which is excellent.
Hope it helps,
Roy
