TTCN-3 log file merge utility

## NAME

ttcn3\_logmerge - TTCN-3 log file merge utility

## SYNOPSIS

**ttcn3\_logmerge** \[ **-o** *outfile* \] *file.log* ...\

## DESCRIPTION

This manual page is a quick reference for the TTCN-3 logmerge utility of the TTCN-3 Test Executor. The  **ttcn3\_logmerge** utility, which can be found in  *$TTCN3\_DIR/bin,* merges all files given in the command argument into a single output file. The output of **ttcn3\_logmerge** is sorted based on the timestamps found in the log files.\
 It is useful for test suites that are run in parallel mode. It can merge the logs of different PTC into one single file based on the timestamps.

## OPTIONS

Available command line switches are:

- **-o** *outfile*

  Merges all input log files into  *outfile*. If the file outfile exists its contents will be overwritten. This switch is optional, when omitted merged logs will be printed to standard output.

- **-v**

  Prints *version* and license key information and exits.

## ENVIRONMENT VARIABLES

- TTCN3\_DIR

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

- TTCN3\_LICENSE\_FILE

  It shall point to the *file* (**NB:** *not* to its directory) that contains the personalized license key for the current user or host.
