## NAME

condor\_tail - HTCondor Manual

Display the last contents of a running job's standard output or file

## 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**.

- **-debug**

- **-follow**

  Repetitively tail the file(s), until interrupted.
