SYNOPSIS

       condor_tail [-help ] | [-version ]

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

DESCRIPTION

       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.
