clarification on external filter

Hi all,

I have few newbie questions.

PS: I don't have PX installed to verify (I am just going through documents)

a) external filter - can we write any unix command (rm/find/grep/awk/sed/cut...) etc?

b) Can I write unix scripts to process .ds files (just as txt files) and use external filter

c) Does external filter wrap the commands with osh command?

Thanks

The answers you seek are in the manual.

(a) There are restrictions on the commands that can be executed, but in summary the commands that are used must be "pipe safe".

(b) "*.ds" files are Data Set descriptor files. They are binary files. You should never attempt to process these with any UNIX command. The only commmand you should use with these files is orchadmin.

(c) There's no reason to do so. Therefore no. The command in the stage is, however, invoked via an Orchestrate operator (player process) which IS running osh.
