I have a perl script that just does a `du -sk -x` and formats it to look groovy ( the argument can be a directory but usually is like /usr/local/* )
The script works fine and does all that i want it to and i use it all the time, however is there an internal perl function that could replace the du -sk -x? I am just curious and would like to have a pure perl script with no shell options (primarily because the du options are not standard across the UNIX/Linux world). This is on a RHEL box just FYI. An external module might work too, if i can get them to let me install it.

pegasus-config
PEGASUS-CONFIG(1)PEGASUS-CONFIG(1)NAME
pegasus-config - The authority for where parts of the Pegasus system exists on the filesystem. pegasus-config can be used to find libraries
such as the DAX generators.
SYNOPSIS
pegasus-config [-h] [--help] [-V] [--version] [--noeoln]
[--perl-dump] [--perl-hash] [--python-dump] [--sh-dump]
[--bin] [--conf] [--java] [--perl] [--python]
[--python-externals] [--schema] [--classpath]
[--local-site] [--full-local]
DESCRIPTION
pegasus-config is used to find locations of Pegasus system components. The tool is used internally in Pegasus and by users who need to find
paths for DAX generator libraries and schemas.
OPTIONS -h, --help
Prints help and exits.
-V, --version
Prints Pegasus version information
--perl-dump
Dumps all settings in perl format as separate variables.
--perl-hash
Dumps all settings in perl format as single perl hash.
--python-dump
Dumps all settings in python format.
--sh-dump
Dumps all settings in shell format.
--bin
Print the directory containing Pegasus binaries.
--conf
Print the directory containing configuration files.
--java
Print the directory containing the jars.
--perl
Print the directory to include into your PERL5LIB.
--python
Print the directory to include into your PYTHONLIB.
--python-externals
Print the directory to the external Python libraries.
--schema
Print the directory containing schemas.
--classpath
Builds a classpath containing the Pegasus jars.
--noeoln
Do not produce a end-of-line after output. This is useful when being called from non-shell backticks in scripts. However, order is
important for this option: If you intend to use it, specify it first.
--local-site [d]
Create a site catalog entry for site "local". This is only an XML snippet without root element nor XML headers. The optional argument
"d" points to the mount point to use. If not specified, defaults to the user's $HOME directory.
--full-local [d]
Create a complete site catalog with only site "local". The an XML snippet without root element nor XML headers. The optional argument
"d" points to the mount point to use. If not specified, defaults to the user's $HOME directory.
EXAMPLE
To set the PYTHONPATH variable in your shell for using the Python DAX API:
export PYTHONPATH=`pegasus-config --python`
To set the same path inside Python:
config = subprocess.Popen("pegasus-config --python-dump", stdout=subprocess.PIPE, shell=True).communicate()[0]
exec config
To set the PERL5LIB variable in your shell for using the Perl DAX API:
export PERL5LIB=`pegasus-config --perl`
To set the same path inside Perl:
eval `pegasus-config --perl-dump`;
die("Unable to eval pegasus-config output: $@") if $@;
will set variables a number of lexically local-scoped my variables with prefix "pegasus_" and expand Perl's search path for this script.
Alternatively, you can fail early and collect all Pegasus-related variables into a single global %pegasus variable for convenience:
BEGIN {
eval `pegasus-config --perl-hash`;
die("Unable to eval pegasus-config output: $@") if $@;
}
