[ast-users] String of parameters passed to a script.

[Tom K.]

Hey Gents,

When trying to pass a variable of paramters to another script, to reduce 
amount of code:

OPT1="This is my Option";
OPT2="/folder/file";
PARMS="-u \"me\" -J \"$OPT1\" -g \"$OPT2\"";

then passing it in like this:

./script.ksh -n 1 "$PARMS";

I get this:

UARG=| "me" -J "This is my Option" -g "/folder/file"|

Or I get this:

UARG=|"me"|

when I try to pass it in this manner:

./script.ksh -n 2 ${PARMS};

Looks like it manages to grab a part of what's in $PARMS but not the 
rest of the string.  Was curious about this behaviour and if KSH had any 
way to make this work?  Full code is below.  Tried a couple of 
variations including ' but no luck.  This is an older KSH93 version.  I 
don't have the option of changing this version unfortunately.

Cheers, Tom

# cat main.ksh
#!/usr/bin/ksh93

OPT1="This is my Option";
OPT2="/folder/file";

PARMS="-u \"me\" -J \"$OPT1\" -g \"$OPT2\"";

./script.ksh -n 0 -u me -J "$OPT1" -g "$OPT2";
./script.ksh -n 1 "$PARMS";
./script.ksh -n 2 ${PARMS};
./script.ksh -n 3 "${PARMS}";
./script.ksh -n 4 $PARMS;


# cat script.ksh
#!/usr/bin/ksh93


while getopts n:u:g:J: option; do
        case ${option} in
                n)      NARG="$OPTARG"
                        ;;
                u)      UARG="$OPTARG"
                        ;;
                g)      GARG="$OPTARG"
                        ;;
                J)      JARG="$OPTARG"
                        ;;
                [?])    print >&2 "Good Luck!";
                        exit 1
                        ;;
                esac
