R help - Sep 2009 - How to get the current script file name in the script?

Hi,

Right now, I hardcode the file name in the script. But when I change
the script name, I have to change the file name in the script to make
sure the file name inside the script is synchronized with the script
name. I am wondering if there is an automatic way to get the script
file name in a script.

Regards,
Peng

$ Rscript get_file_name.R
> print('get_file_name.R')
[1] "get_file_name.R"
>

Try this one line R script:

print(sub(".*=", "", commandArgs()[4]))

Also see the geopt package for fancier handling of arguments.
