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) 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 <>.

BUGS

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