The ooRexx V5.0.0.r12194 Language Reference (the most recent I have
downloaded), section
2.1. ADDRESS says,
| The following evironments are available in ooRexx:
| sh (Unix only)
| This is the default environment on Unix systems. It uses sh as a shell
program to
execute the command. All shell features such as redirection or piping can be
used.
|
| bsh, bash, csh, ksh, tcsh, zsh (Unix only)
| These environments use alternate Unix shells bsh, bash, csh, ksh, tcsh,
or zsh to
execute the command. If the appropriate shell is not installed on the system,
executing a
command in any of these enviroments will raise a failure.
|
| cmd (Windows only)
| This is the default environment on Windows systems. It uses cmd.exe as a
command
interpreter to execute the command. Command interpreter features such as
internal
commands, redirection or piping can be used.
|
| command, system, ""
| These environment names are synonyms for the default environments sh on
Unix and cmd
on Windows.
| :
I intend to switch from the bash shell I'm currently using to the fish
shell, which
appears to be much more programmer-friendly than any of the sh-based shells.
Can fish be
added to the list of Unix shells recognized by ooRexx?
Alternatively, it would be nice if ooRexx used the value stored in
/etc/passwd for the
user account, e.g.
| leslie:x:1000:100:Leslie Turriff:/home/leslie:/usr/bin/fish
that makes my default shell /usr/bin/fish; or ooRexx could use /usr/bin/which
to determine
if the requested environment is installed. Either of these would allow Unix
shells not
on the Official List to be used. (It would be the programmer's responsibility
to ensure
that the environment does in fact point to a valid shell.)
