Using env doesn't solve the problem either. There is no guarantee the "env" program is installed under /usr/bin/env. It may as well be installed under /usr/local/bin/env. But every unix should have a bourne shell compatible shell located at /bin/sh. You can use a bourne shell compatible code snippet and call zsh from it. If PATH contains zsh than this will do the trick. #!/bin/sh if [ -z "$ZSH_VERSION" ]; then ## searching PATH for zsh executable exec zsh $* < $0 ## no zsh detected exit 1 fi ## zsh should be running now. do zsh stuff print "hello"
