2.15 Potential Problems

2.15.1 Renaming of argv[0]

When HTCondor starts up your job, it renames argv[0] (which usually contains the name of the program) to condor_exec. This is convenient when examining a machine's processes with the Unix command ps; the process is easily identified as an HTCondor job.

Unfortunately, some programs read argv[0] expecting their own program name and get confused if they find something unexpected like condor_exec.
