Try to use a loop, let, and printf for the padding: a=1 for i in *.jpg; do new=$(printf “%04d.jpg” “$a”) #04 pad to length of 4 mv -i — “$i” “$new” let a=a+1 done using the -i flag prevents automatically overwriting existing files, and using — prevents mv from interpreting filenames with dashes as options.
