condor_tail [-pool centralmanagerhostname[:portnumber]] [-name name] [-debug ] [-maxbytes numbytes] [-auto-retry ] [-follow ] [-no-stdout ] [-stderr ] job-ID [filename1 ] [filename2 ... ]


condor_tail displays the last bytes of a file in the sandbox of a running job identified by the command line argument job-ID. stdout is tailed by default. The number of bytes displayed is limited to 1024, unless changed by specifying the -maxbytes option. This limit is applied for each individual tail of a file; for example, when following a file, the limit is applied each subsequent time output is obtained.

If you specify filename, that name must be specifically listed in the job's transfer_output_files.
