Turns out I only had one bash-specific feature in the original script. I'll test it on my home machine for a few days and then release it. I's intended for the Gentoo mailing list. Would it be of interest to the busybox list or any wiki it may have? -- Walter Dnes ___ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox

POSIX is defined there: http://pubs.opengroup.org/onlinepubs/9699919799/toc.htm The page specific to the shell is: http://pubs.opengroup.org/onlinepubs/9699919799/toc.htm The page specific to the shell language is: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18 In any case, I now only use POSIX constructs for shell scripts I intend to be portable, and/or to be 'embedded'. This (somewhat) guarantees that I can run the scripts on my desktop machine, and on my embedded system(s), without having to care about the actual shell ( heck, no, I do not care about csh or zsh, or any non POSIX-compliant shells :-] ) Regards, Yann E.

I always found the man page of Debian ash to be very helpful and quite precise when doing special shell scripts for my embedded BusyBox environment. Just install a dash package and type "man dash" or read this: http://linux.die.net/man/1/dash -- Alexander Kriegisch ___ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
Is there a detailed manual for busybox's ash?
I've got automount (and auto-unmount) working with mdev. Right now, the code is in a bash script. It's intended for use in Gentoo linux. But I could see others being interested in it. For maximum portability, I figure that the script should be in busybox ash. I.e., if you've got busybox mdev, you have busybox, and therefore busybox ash. I can imagine that some lightweight systems would try to avoid having another shell like bash. I'd like to re-do the automount script in ash, but I don't have any idea where to find detailed busybox ash syntax documentation. A Google search for busybox ash documentation turns up... a whole bunch of other people asking where to find detailed busybox ash syntax documentation Any pointers? -- Walter Dnes ___ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
