Scripts that take String options
I need help to know how to create a script that takes string options and not only 1 charecter.
I wanted to make a script that takes 'string' options eg. hscript.sh -product XXX -version XXX I know that I can make a script that takes "1 Charecter " options eg. hscript.sh -m XXX -l XXX -s XXX , with a function called "getopts". When i tried to use "getopts" to make the options as a string and not only 1charecter the script didn't work. |

Try using a while loop to process the parameters, e.g...
Code:
while [[ $# -gt 0 ]]
do
case $1 in
-product) export PRODUCT=$2 ; shift ;;
-version) export VERSION=$2 ; shift ;;
*) echo invalid option ; exit 1 ;;
esac
shift
done

Hi.
I think Ygor's suggestion is relatively easy to implement and useful to know about. However, there are those extra actions with which getopts-like facilities can help us -- error messages, shifting, etc. There is a shell version of getopt that can process long options. See Bash long options and Python s-expression parser for details ... cheers, drl Last edited by drl; 10-19-2007 at 08:09 AM.. Reason: Clarify meaning. |
