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

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