Passing parameter filled variable to a script.
Say I have something like this to try and build a parameter string:

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

PARMS="-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;

But this doesn't work. For example, it just sees "This" passed instead of the whole string. Parameters without spaces seem fine. Is there anyway to do so? Tried ' and { and combinations of but no luck. Can't seem to pass the whole string in. Here's how it looks (' "This ' is printed but not the whole string):

Code:
# ./dummy.ksh
NARG=|1|
UARG=|me|
GARG=||
JARG=|"This|

NARG=|2|
UARG=|me|
GARG=||
JARG=|"This|

NARG=|3|
UARG=|me|
GARG=||
JARG=|"This|

NARG=|4|
UARG=|me|
GARG=||
JARG=|"This|

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


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
done


print "NARG=|$NARG|";
print "UARG=|$UARG|";
print "GARG=|$GARG|";
print "JARG=|$JARG|";
print;
# cat dummy.ksh
#!/usr/bin/ksh

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

PARMS="-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;

#

Passing directly works fine, but not through a parameter of flags.

Cheers,
DH

build-lives-rfx-plugin-multi

build-lives-rfx-plugin-multi(1) 			      General Commands Manual				   build-lives-rfx-plugin-multi(1)

NAME

       build-lives-rfx-plugin-multi - builds rendered effects for LiVES

SYNOPSIS

       build-lives-rfx-plugin-multi type [scripts_dir exec_dir] [build_bindir]

DESCRIPTION

       This  perl  script  builds  rendered  effects (RFX) plugins for LiVES. If scripts_dir is not defined then type is used to locate the plugin
       scripts directory and output directory. Type can be builtin (the default), custom,
	test, or builtinx. The type builtinx forces scripts_dir and exec_dir to be read from parameters and is used during LiVES install,  and	is
       the only type which should be used if scripts_dir is specified.

       Each  plugin script in input directory is scanned to find its language code. The script is then passed to the script compiler for that lan-
       guage.  The directory location of the script_compiler may be specified by the build_bindir parameter (as is the case during LiVES installa-
       tion0; otherwise the user's $PATH will be searched.

       Return values the script returns the following values

       0 - success 1 - the "type" parameter was not defined, or set to an invalid value 3 - the builder for a plugin script was not found
