: Shell Answer
: bsh sh (True Bourne Shell, SVR4)
: ash sh (Almquist Shell, /bin/sh in 4.4BSD)
: ksh ksh (True Korn Shell, SVR4)
: pdksh bash (public domain Korn Shell)
: bash bash
: zsh ksh
Hmmm, if zsh says that, I'll have to give it a go (I like the fact that
the real ksh inlines the last bit of a pipe). I'll change my script
to do some of the stuff with {} so that it can identify zsh. I've got
pdksh now too so I'll see if I can identify that too. Any advances ?
Of course,
ps opid,command | grep " *$pid " | sed 's/.* //'
doesn't count !
