Getopts alternative

Shell Programming and Scripting
1

Hi,

Does anyone have an example of parsing command line arguments similar to how getopts parse command line arguments?

I am looking at a getopts alternative because I want to have the same parsing on the subroutine/function in the script.

For example, I want to be able to do test.ksh -p 1 -d /tmp but inside the script I want to be able to do do a sub1 -u test01 -o remove.

By using an alternative to getopts, it won't be confusing understanding how I parse argument either from the script or from the subroutines/functions.

Any advice much appreciated. Thanks in advance.

getopts works inside subroutines. Just be sure to set OPTIND to 1 at the beginning of your functions, since this global value may be left at something strange from your last function.

Assuming you are using the ksh93 version of getopts, you can get the current documentation for it using:

getopts --man

This provides more complete and up-to-date documentation than the ksh manpage.

Hi.

See also post #5 in thread Using getopts for handling multiple options for several different alternatives (in the sense of methods) for parsing arguments ... cheers, drl
