How to execute command from spec file
 

I am installing one application installation setup in SUSE 10.2 which can get successful if I execute from command line, but get failed if I execute the same command from post section of spec file.

As I know if there are pre and post section in spec file then while installing rpm, it generates the pre and post scripts in /var/tmp folder for execution. Installation gets passed if I execute the script manually but failed from post section of the spec file.

Can you suggest why this is happening?

Post the details please and be verbose: commands, scripts, spec file, errors.
