Hi Guys,

I am busy trying to re-write a shell script that was written way back.

I need help with these codes:

# Process switches
if [ $? -gt 1 ] ; then
  echo "usage : process <optional instance>"
  exit 99
fi

SIDA=true
SIDB=true

if [ $# -eq 1 ] ; then
  if [ $1 = "SIDA" ] ; then
    SIDB=false
  fi
  if [ $1 = "SIDB" ] ; then
    SIDA=false
  fi
fi

The $ sign expands (=replaces) parameters/variables to (with) their contents. 1, 2, ... are positional parameters, of which $# is the count; $? yields the exit code/status of your last command. Read the man page of your shell.

Thanks for the replies...
