How to run a sequence of scripts?
Assume I want to run a sequence of scripts:

Code:
script0001.sh
script0002.sh
script0003.sh
...
script0122.sh
script0123.sh

I only know a little Linux scripting, so the following is the best I can write

Code:
for k in $(seq 1 123)
do
   ./script${k}.sh
done

Of course it doesn't work because I don't know how to pad zeros. Could you please help me with it? Thanks a lot!

Without knowing what shell you're using, it is hard to give the most efficient way to do this. A portable way that will work with any shell that provides features required by the POSIX standards would be:
Code:
i=1
while [ $i -le 123 ]
do	cmd=$(printf './script%04d.sh' $i)
	$cmd
	i=$((i + 1))
done

In bash version 4 and up on Linux/Unix you can also do this:
Code:
for scr in script{0001..123}.sh
do
  ./scr
done

This also works in zsh
