# dprof2calltree(1)

convert perl's DProf profiling data to KCachegrind calltree format

## NAME

dprof2calltree - convert perl's DProf profiling data to KCachegrind calltree format

## SYNOPSIS

**dprof2calltree** **-f** *input* \[ **-o** *output* \]

## DESCRIPTION

**dprof2calltree** reads the *tmon.out* profiling data output by Perl's Devel::DProf profiling package, and converts it into calltree format for use by KCachegrind.

This utility is part of the KDE Software Development Kit.

## OPTIONS

- **-f** *input*

  Specifies the DProf *tmon.out* file to convert.

- **-o** *output*

  Write the calltree output to the given file for use by KCachegrind. If omitted, the output will be written to file of the form *cachgrind.out.\<input\>*.

## EXAMPLE

If you run a perl script as:

perl -d:DProf yourscript.pl

then this will write profiling data to *tmon.out*.  You can then work with this data in KCachegrind as follows:

dprof2calltree -f tmin.out -o cachegrind.out.foo\
 kcachegrind cachegrind.out.foo
