# logprn(1)

merge Common-Log Format web logs based on time-stamps

## NAME

logprn - merge Common-Log Format web logs based on time-stamps

## SYNOPSIS

**logprn logfile idle-time\[:max-wait\] command**

## DESCRIPTION

The **logprn** program is designed to print new data that is appended to log files.  It will wait until a specified amount of time has elapsed since the last write to the file before printing the data.  It will print the data by pipeing it to a specified command.  The command will be run by [popen(3)](/popen/3.md) so the usual shell commands will operate (whether this is a bug or a feature is a matter of opinion).

## OPTIONS

- **logfile**

  specifies a file to read data from.  It should be a regular file not a pipe, device, or anything else.

- **idle-time**

  - **max-wait**

  - **command**

  ## EXIT STATUS

**0** Never happens, this program will run forever.

**1** Bad command-line parameters or couldn't stat the log file on startup - couldn't start the program.

**2** File disappeared or became unreadable at run-time.

**3** Can't run the specified command.

## AUTHOR

This program, its manual page, and the Debian package were written by Russell Coker \<russell@coker.com.au\>.

## BUGS

Uses **popen (3)** but I consider this a feature not a bug.
