This beats Optimus_P's solution by only choosing the lines that have the terms you're looking for as whole words (a failing of egrep). If your logfile is huge (multimegabytes) you can gain a slight performance advantage with this:
Re: Learning Perl: This is a really good book, but if you're an experienced programmer, the man pages are sufficient. Read 'man perl' thouroughly, and you'll learn the best order in which to go through them.

PERLIVP(1) Perl Programmers Reference Guide PERLIVP(1)NAME
perlivp - Perl Installation Verification Procedure
SYNOPSIS
perlivp [-p] [-v] [-h]
DESCRIPTION
The perlivp program is set up at Perl source code build time to test the Perl version it was built under. It can be used after running:
make install
(or your platform's equivalent procedure) to verify that perl and its libraries have been installed correctly. A correct installation is
verified by output that looks like:
ok 1
ok 2
etc.
OPTIONS -h help
Prints out a brief help message.
-p print preface
Gives a description of each test prior to performing it.
-v verbose
Gives more detailed information about each test, after it has been performed. Note that any failed tests ought to print out some
extra information whether or not -v is thrown.
DIAGNOSTICS
o print "# Perl binary '$perlpath' does not appear executable.
";
Likely to occur for a perl binary that was not properly installed. Correct by conducting a proper installation.
o print "# Perl version '$]' installed, expected $ivp_VERSION.
";
Likely to occur for a perl that was not properly installed. Correct by conducting a proper installation.
o print "# Perl @INC directory '$_' does not appear to exist.
";
Likely to occur for a perl library tree that was not properly installed. Correct by conducting a proper installation.
o print "# Needed module '$_' does not appear to be properly installed.
";
One of the two modules that is used by perlivp was not present in the installation. This is a serious error since it adversely affects
perlivp's ability to function. You may be able to correct this by performing a proper perl installation.
o print "# Required module '$_' does not appear to be properly installed.
";
An attempt to "eval "require $module"" failed, even though the list of extensions indicated that it should succeed. Correct by
conducting a proper installation.
o print "# Unnecessary module 'bLuRfle' appears to be installed.
";
This test not coming out ok could indicate that you have in fact installed a bLuRfle.pm module or that the "eval " require
"$module_name.pm"; "" test may give misleading results with your installation of perl. If yours is the latter case then please let
the author know.
o print "# file",+($#missing == 0) ? '' : 's'," missing from installation:
";
One or more files turned up missing according to a run of "ExtUtils::Installed -> validate()" over your installation. Correct by
conducting a proper installation.
For further information on how to conduct a proper installation consult the INSTALL file that comes with the perl source and the README
file for your platform.
