I need to use getopt option and I have no idea what it is or how to use it.
The idea behind getopt is, instead of having the first argument always be the source, the second argument always the destination, the third a conversion type, the fourth a debug file, the fifth just a flag, etc, etc, etc, your script would take parameters like:
...in any order, so this would have the same effect:
There's a scripting builtin for this called getopts. Here's an example with two arguments to expand however you wish. The -i argument expects a string, the -f argument does not.
Note the string ":i:f". The very first : tells it to fill in OPTARG when its supposed to. The : following i tells it that i expects an argument. There's no : following f, meaning f expects no argument.
This script can then process arguments in any order the same way. You're being asked to build a simple shell wrapper around your awk script to do the same thing I believe.
I am trying to code for the addition of a new argument to the command line, the option D to a code that already has ABC (below). When I use make to compile it, it displays: invalid option --D. I did define the global d variable, as well as initialized it inside the main function of the C code. I... (9 Replies)

To find all the files in your home directory that have been edited in some way since the last tar file, use this command:

Hi all,
I am parsing command line options using getopts.
The problem is that mandatory argument options following ":" is taking next option as argument if it is not followed by any argument.
Below is the script:
while getopts :hd:t:s:l:p:f: opt
do
case "$opt" in

while :
do
case "$1" in
-a) a=1;;
-b) b=1;;
-c) c=1;;
-o) shift; o="$1";;
--) break;;
