## DESCRIPTION

This manual page is a quick reference for the TTCN-3 logfilter utility of the TTCN-3 Test Executor. The  **ttcn3\_logfilter** utility, which can be found in  *$TTCN3\_DIR/bin,* filters the input log file given in the command line argument based on the event types in the file, and filter parameters given in the program argument. The output is then written to an output file if specified, or to the standard output. The program is useful only if the variable **LogEventTypes** is set to **Yes** in section **\[LOGGING\]** of the configuration file.

## OPTIONS

Available command line switches are:

- **-h**

  Prints *help* on how to use the utility.

- **-l**

  Prints the *list* of supported event types.

- **-o** *outfile*

  Puts its output into  *outfile*. If the file outfile exists its contents will be overwritten. This switch is optional, when omitted the output will be printed to standard output.

- **-v**

  Prints *version* and license key information and exits.

## ENVIRONMENT VARIABLES

  The installation directory where the uncompressed binary package of TTCN-3 Test Executor can be found.
