Hi everyone,

bchdicut*. gdx in gams. Could anybody helps me this this problem?
Thank you so much!!

rm is the unix command to delete files or directories.
-rf is the argument given to rm to delete recursively (r)
and to force (f) deletion (ie, not prompt the user for confirmation).
bchdicut*.gdx means that any file or directory that begins with bchdicut
and ends with .gdx will be deleted.

Hi Harrod,
Thank you so much for you answer. But I am still not very
understand about rm and -rf. Could you please show me an example of
that, how this syntax implemented? In addition, when should we use
this kind of syntax?
I appreciate your help a lot!

Ok, well $call tells gams to execute a command in the operating system.
$call rm -rf bchdicut*.gdx
Everything after call is either a command or command line arguments. Are
you using a Unix system (e.g. linux?). The person who wrote the gams file
you're using wanted to delete some files, specifically they wanted to
delete all of files that matched the pattern bchdicut*.gdx. If you want to
know about the rm command, you can type the following at the command line:
man rm
