Can any one help me in resolving the issue? I am pasting the actual content of the script below.plz check it. I am having problem with the code in red.

case "$*" in
*rv:1.[7-9]*) return 0;;
*rv:[2-9].[0-9]*) return 0;;
*rv:*) return 1;;
Mozilla\ 1.[7-9]*) return 0;;
Mozilla\ [2-9].[0-9]*) return 0;;
*) return 1;;
esac
}
 
supportedFirefoxVersion() {
case "$*" in
*Firefox\ [1-9].*) return 0;;
*Firefox/[1-9].*) return 0;;
*Firefox*) return 1;;
*rv:1.[7-9]*) return 0;;
*rv:[2-9].*) return 0;;
*rv:*) return 1;;
Mozilla*\ 1.[7-9]*) return 0;;
Mozilla*\ [2-9].[0-9]*) return 0;;
*) return 1;;
esac
}
whichBrowser=NoBrowser
case "$0" in
/*) fullpath=$0;;
*) fullpath=`pwd`/$0;;
esac
installsourcepath=`echo "$fullpath" | sed "s,/\./,/,g; s,/[^/][^/]*/\.\./,/,g; s,//,/,g; s,/[^/]*$,,"`
if [ "$BROWSER" ]; then
if versionString=`($BROWSER -version) 2>/dev/null`; then
case "$versionString" in
*Firefox*) if supportedFirefoxVersion "$versionString"; then
whichBrowser=Firefox

[: =: unary operator expected
HI radulov,
I've run the script with trace option. and the output is attached below.
and one more thing, the browser is going to safe mode disabling all the efects before it shows the unary operator error.

Could you enable the trace for the /nfs/opt/launchpad/Firefox.sh also and repost the entire output?
And please post the entire code of launchpad.sh.
