startup.sh contains these lines. Can anyone help explain what do they do? Thanks!
# resolve links - $0 may be a softlink
while [ -h "$PRG" ] ; do
ls=`ls -ld "$PRG"`
link=`expr "$ls" : '.*-> \(.*\)$'`
if expr "$link" : '.*/.*' > /dev/null; then
# Check that target executable exists
if [ ! -x "$PRGDIR"/"$EXECUTABLE" ]; then
echo "Cannot find $PRGDIR/$EXECUTABLE"
echo "This file is needed to run this program"
exec "$PRGDIR"/"$EXECUTABLE" start "$@"
