You get very used to writing in the restricted common subset when you have software that has to work on Solaris /bin/sh, but remembering what's allowed and what isn't is complex enough that it's a lot easier to write *all* your shell scripts in that restricted common subset and be sure. I get nervous when I even use shell functions. :) -- Russ Allbery ([EMAIL PROTECTED]) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
