Perl is a scripting language run by the interpreter program - conveniently called 'perl'. So what you were doing was using your shell to run the perl interpreter and tell it which script to run. Alternatively, you can tell the shell which interpreter to use by putting the interpreter name inside the script. Do this by
having a line similar to
as the first line of your script - replace /usr/bin/perl with the path to your perl interpreter if your system is different.

If I use 2 system commands in a script, will one finish before the next one starts? or will it start the first and the second at the same time?
i.e.
system("ps | grep rminer");
system("ls -al | grep 431"); (1 Reply)

perlivp - Perl Installation Verification Procedure
SYNOPSIS
perlivp [-a] [-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.
-a run all tests
Normally tests for optional features are skipped. With -a all tests are executed.
-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",+($#missing == 0) ? '' : 's'," missing from installation:
";
One or more files turned up missing according to a run of "ExtUtils::Installed -> validate()" over your installation. Correct by
conducting a proper installation.
o print "# Perl header `$_' does not appear to be properly installed.
";
Correct by running h2ph over your system's C header files. If necessary, edit the resulting *.ph files to eliminate perl syntax
errors.
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.
