In zsh, when I have to create a bunch of files with zsh, I usually do something like:
for x in $(seq 1 1000); do .....; done
This works fine, it gives me files with names foo-1.txt .. foo-1000.txt.
However, these files do not sort nicely, so I would like to zero-pad the $x variable, thus producing names of foo-0001.txt .. foo-1000.txt.
How to do that in zsh? (and bonus question, how to do it in bash?)
Use the -w flag to seq (in any shell):
$ seq -w 1 10
