This question sounds like "are cars usually red"? There are without a doubt a lot of red cars, but this means nothing if you what to know if this specific car is red or not. What you are interested in is, if the software is installed on the specific system you want to run some script on. If some other systems have it or not doesn't matter.

What "UNIX" constitutes is defined in the "Single Unix Specification", the "POSIX" specification and similar documents. Today a UNIX system is not required to use some specific (AT&T-) code, but to react in a (thusly) specified way. "awk" is part of this specification, "perl" is not. And neither is "python". If you want to write portable scripts you should consider using the POSIX shell (which resembles mostly the ksh88).

The system i use most - AIX - definitely doesn't have it in the default install and for AIX - as well as any other systems i use - the term "default install" is meaningless. When i install a production system i use a carefully crafted absolute-minimum-image ("golden image") and install of this what is needed. What can be expected because of the POSIX specification is there (all tools listed as "mandatory"), but not more. Everything installed will have to be maintained, can break, etc. and if you have thousands of systems in a data center (quite the common case) you want to keep the things which can break at an absolute minimum.

I hope this helps.

debuginfo-install

debuginfo-install(1)													      debuginfo-install(1)

NAME

       debuginfo-install - install debuginfo packages and their dependencies

SYNOPSIS

       debuginfo-install package

DESCRIPTION

       debuginfo-install  is a program which installs the RPMs needed to debug the specified package.  The package argument can be a wildcard, but
       will only match installed packages.  debuginfo-install will then enable any debuginfo repositories, and install the relevant debuginfo rpm.

EXAMPLES

       Download and install all the RPMs needed to debug the kernel RPM:
	      debuginfo-install kernel

WARNING MESSAGES

       Could not find debuginfo for:
	      You may sometimes see warning messages about certain packages not being found if you run debuginfo-install for a wildcard  or  glob.
	      Debuginfo  packages are not necessary for "noarch" RPMs; these will generate a warning message.  Additionally, On 64-bit systems, no
	      multilib debuginfo packages are published, so if you have 32-bit packages installed, these will also generate warning messages.

FILES

       As debuginfo-install uses YUM libraries for retrieving all the information, it relies on YUM configuration  for	its  default  values  like
       which repositories to use. Consult YUM documentation for details:

       /etc/yum.conf
       /etc/yum/repos.d/
       /var/cache/yum/

BUGS

       There  are  of  course no bugs, but should you find any, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if
       unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org.  To file a bug  use	http://bugzilla.redhat.com
       for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs.
