#1342: grass.core.find_program() problem with ssh and other ---+ Reporter: lucadelu | Owner: grass-dev@… Type: defect| Status: closed Priority: normal| Milestone: 7.0.0 Component: Python| Version: svn-trunk Resolution: invalid |Keywords: python find_program Platform: Linux | Cpu: Unspecified ---+ Changes (by lucadelu): * status: new = closed * resolution: = invalid Comment: Replying to [comment:1 glynn]: In order for find_program() to work, you need to find some invocation which returns a zero exit status (indicating success). If running the command with --help is considered an error (non-zero exit status), you'll need to find some other option. E.g. for ssh, you can use ssh -V.

Whether the program prints anything to either stream is entirely irrelevant; find_program() simply checks the return code. In order for find_program() to work, you need to find some invocation which returns a zero exit status (indicating success). If running the command with --help is considered an error (non-zero exit status), you'll need to find some other option.
