created a shell script requiring 2 input parameters
created a custom command that calls this script and enabled Public Access
When I use the link that is specified in the Dashboard tab for Custom Commands then this is working fine except that I do not know how I can pass my 2 input parameters in the url.
Ah,yes the commands module tokenizes the arguments itself, so instead of .../arg1/arg2 it should be .../arg1%20arg2 (basically url-encode the entire space separated argument list).
