In particular, the /bin/sh that came with V7 didn't and consequently the /bin/sh that comes with 4.[0-3]BSD still doesn't. The Korn shell supports both aliases and shell functions; you can say either: alias ls="/bin/ls -CBb" or: ls() { /bin/ls -CFb "$@" # Note the "" } and the effect is pretty much the same. Hope this clarifies things a bit, Hans Mulder hansm@cs.kun.nl

One further point. A Korn shell alias does not handle command-line arguments. The Korn equivalent to a C-shell alias such as: alias svi 'sccs edit -s \!*; vi \!*; sccs delget -s \!*' would be: svi() { # edit SCCS files sccs edit -s "$@" vi "$@" sccs delget -s "$@" } -r
