Indeed.
According to the OpenGroup that syntax should be fine: http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_...
It works for me under Solaris 10. Perhaps Solaris 9 or older do not have a standard compliant /bin/sh program. What do you suggest we use instead as a workaround?
For backward compatibility reasons sh in Solaris 9 and earlier is not POSIX compliant. Use /usr/xpg4/bin/sh or /bin/bash instead. (Unfortunately you can't cheat and define a shell function, although you could create a program called "!": #! /bin/sh if ${1+"$@"}; then exit 1 else exit 0 fi .) -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
