[arch-general] OT: dash - looping through alphabet

[Ralf Mardorf]

Hi!

Sorry, it's OT for this list, but I didn't find an answer in the
Internet.

What's the syntax for a loop from "a" to "z" in dash?

[rocketmouse at archlinux src]$ cat for-bash 
#!/bin/bash
for str in {a..z} ; do printf "$str"; done
printf "\n"
exit

[rocketmouse at archlinux src]$ cat for-dash 
#!/bin/dash
for str in {a..z} ; do printf "$str"; done
printf "\n"
exit

[rocketmouse at archlinux src]$ ./for-bash 
abcdefghijklmnopqrstuvwxyz
[rocketmouse at archlinux src]$ ./for-dash 
{a..z}

Regards,
Ralf
