I have this:
Code:
#!/bin/bash
# Argument = -t test -r server -p password -v usage()
{
  cat << EOF
usage: $0 options
 This script run the test1 or test2 over a machine.
 OPTIONS:
    -h        Show this message
    -t        Test type, can be ‘test1′ or ‘test2′
    -r        Server address
    -p        Server root password
    -v        Verbose
EOF
}
 TEST=
SERVER=
PASSWD=
VERBOSE=
while getopts “ht:r:p:v” OPTION
do
      case $OPTION in
            h)
                  usage
                  exit 1
                  ;;
            t)
                  TEST=$OPTARG
                  ;;
            r)
                  SERVER=$OPTARG
                  ;;
            p)
                  PASSWD=$OPTARG
                  ;;
            v)
                  VERBOSE=1
                  ;;
            ?)
                  usage
                  exit
                  ;;
     esac
done
 if [[ -z $TEST ]] || [[ -z $SERVER ]] || [[ -z $PASSWD ]]
then
      usage
      exit 1
fi

when I run any other options it gives me the message:
Quote:
./myscript: illegal option -- r
This is controlled by the command not my script and I don't have such a message. How can I get rid of that error?

endusershell

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/ksh93		    /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/ksh93 	    /usr/bin/pfcsh
	 /usr/bin/pfksh 	    /usr/bin/pfsh
	 /usr/bin/sh		    /usr/bin/tcsh
	 /usr/bin/zsh		    /usr/sfw/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.

NOTES

       Restricted shells should not be listed in /etc/shells.
