taking command line arguments in bash is fairly easy, heres a piece of code i wrote for a small script a few months ago, most of it is from the tldp.org advanced bash shell scripting guide. what i did was put the first thing ran in the code in a function called "main()". you call this function with:
Code:
main "$@"
main looks like this:
Code:
main ()
{
NO_ARGS=0
E_OPTERROR=65
if [ $# -eq "$NO_ARGS" ] # should check for no arguments
then
echo "Usage: `basename $0` -s<OPTIONS> <HOSTNAME> "
echo "You must specify interactive, or non interactive mode for now"
echo "Try './serverstatus -h' for more information."
exit $E_OPTERROR
fi
while getopts ":sicnvh" Option
do
case $Option in
s )
hostname=`echo $@`
hostname2=`echo $hostname|awk '{print $2}'`
echo $hostname2
a=`nmap $hostname2`
;;
i )
interactivemode_func
;;
c )
add_serv
;;
n )
non_interactivemode_func
;;
v )
version_func
;;
h )
help_func
;;
* )
echo "Unimplemented option chosen"
;;
esac
done
shift $(($OPTIND - 1))
}

print
print(1) User Commands print(1)NAME
print - shell built-in function to output characters to the screen or window
SYNOPSIS
ksh
print [ -Rnprsu [n]] [arg...]
DESCRIPTION
ksh
The shell output mechanism. With no flags or with flag - or -, the arguments are printed on standard output as described by echo(1).
OPTIONS
The following options are supported:
-n suppresses new-line from being added to the output.
-R
-r (raw mode) ignore the escape conventions of echo. The -R option will print all subsequent arguments and options other than
-n.
-p causes the arguments to be written onto the pipe of the process spawned with |& instead of standard output.
-s causes the arguments to be written onto the history file instead of standard output.
-u [ n ] flag can be used to specify a one digit file descriptor unit number n on which the output will be placed. The default is 1.
EXIT STATUS
The following exit values are returned:
0 Successful operation.
>0 Output file is not open for writing.
