Hi.
In the real csh, not tcsh, you probably need to use $status, not $?
This is just one of the many reasons that most people use and recommend Bourne shells (sh, ksh, bash, zsh) for scripting.
Best wishes ... cheers, drl

getusershell
getusershell(3C) Standard C Library Functions getusershell(3C)
NAME
getusershell, setusershell, endusershell - get legal user shells
SYNOPSIS
#include <unistd.h>
char *getusershell(void);
void setusershell(void);
void endusershell(void);
DESCRIPTION
The getusershell() function returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells. If
/etc/shells does not exist, the following locations of the standard system shells are used in its place:
/bin/bash /bin/csh
/bin/jsh /bin/ksh
/bin/pfcsh /bin/pfksh
/bin/pfsh /bin/sh
/bin/tcsh /bin/zsh
/sbin/jsh /sbin/pfsh
/sbin/sh /usr/bin/bash
/usr/bin/csh /usr/bin/jsh
/usr/bin/ksh /usr/bin/pfcsh
/usr/bin/pfksh /usr/bin/pfsh
/usr/bin/sh /usr/bin/tcsh
/usr/bin/zsh /usr/xpg4/bin/sh
The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.
The setusershell() function rewinds the file or the list.
The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.
RETURN VALUES
The getusershell() function returns a null pointer on EOF.
BUGS
All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.
