I want to rename the files in a directory to sequential numbers. Based on creation date of the files.
For Example sadf.jpg
to 0001.jpg
, wrjr3.jpg
to 0002.jpg
and so on, the number of leading zeroes depending on the total amount of files (no need for extra zeroes if not needed).
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.
