如何防止终端回显我的getopts参数？

Question

我正在编写一个包含getopts的脚本，它可以游泳：

#!/bin/bash

# Define help function for options
function help(){
    echo
    echo -e $YELLOW'--->COMMAND LINE OPTIONS:'$ENDCOLOR
    echo
    echo "Usage example:";
    echo "script_name [(-i|--install) string] [(-u|--uninstall) string] [(-b|--backup) string] [(-r|--restore) string] [(-m|--manualupdate) string] [(-p|--passwordreset) string] [(-a|--accessdetails) string] [(-t|--updatetoolkit)] [(-U|--updateall)]";
    echo "Options:";
    echo
    echo "-i or --install string: Install an app.";
    echo "-u or --uninstall string: Uninstall an app.";
    echo "-b or --backup string: Backup an the config file for an app.";
    echo "-r or --restore string: Restore an app config file from backup.";
    echo "-m or --manualupdate string: Manually update a specific app.";
    echo "-p or --passwordreset string: Reset the password to an app.";
    echo "-a or --accessdetails string: View the access details for an app.";
    echo "-t or --updatetoolkit: Update the toolkit.";
    echo "-U or --updateall: Update Linux and all apps.";
    exit 1;
}

# Reset option vars
updatetoolkit=0;
updateall=0;

# Capture options to getopts
export ARGS=$(getopt -o "i:u:b:r:m:p:a:tUh" -l "install:,uninstall:,backup:,restore:,manualupdate:,passwordreset:,accessdetails:,updatetoolkit,updateall,help" -n "script_name" -- "$@");

if [ $? -ne 0 ];
then
    help;
fi

eval set -- "$ARGS";

while true; do
    case "$1" in
        -i|--install)
            shift;
                    if [ -n "$1" ]; 
                    then

                    if [ -n "$1" ];

                        source $SCRIPTPATH/inc/app-password-reset.sh
                        shift;
                    fi
            ;;
        -a|--accessdetails)
            shift;
                    if [ -n "$1" ]; 
                    then
                        accessdetails="$1";
                        source $SCRIPTSOURCE/$1/$1-constants.sh
                        source $SCRIPTPATH/inc/app-access-details.sh
                        shift;

        --)
            shift;
            break;
            ;;
    esac
done

# Check required arguments

但是，每当我使用参数运行脚本时，它会执行它应该执行的操作，但它会在终端中打印参数，即：

-p

Remaining code...

我该如何防止这种情况？
