Problem with * when pass into variable.

Hello expert.

I have a little problem here.
I write a script and stuck some bug to fix.

I found the problem was about * and a sample of script is below.
Quote:
echo "*"
TEST=`echo "*"`
echo $TEST
line 1 is print * out
but line 3 print all name of files in the script's path. (but I want *)

I want to contain * in variable TEST and print it but seem not work.
Any idea? Thank you.

Sorry for my English and if this issue has been discuss before.
It hard to search for topic about a special character *.

NAME
Apache::TestMM - Provide MakeMaker Wrapper Methods SYNOPSIS
require Apache::TestMM; # import MY::test and MY::clean overrides for MM Apache::TestMM->import(qw(test clean)); # parse command line args Apache::TestMM::filter_args(); # autogenerate the script Apache::TestMM::generate_script('t/TEST'); DESCRIPTION
"Apache::TestMM" provides wrappers for the "ExtUtils::MakeMaker" craft, making it easier to extend the autogenerated Makefile with "Apache::Test". FUNCTIONS
"import" use Apache::TestMM qw(test clean); or: Apache::TestMM->import(qw(test clean)); Imports "MY::" overrides for the default "ExtUtils::MakeMaker" test and clean targets, as if you have defined: sub MY::test {...} sub MY::clean {...} in Makefile.PL. "Apache::TestMM" does this for you so that these Makefile targets will run the Apache server and the tests for it, and clean up after its mess. "filter_args" push @ARGV, '-apxs', $apxs_path; Apache::TestMM::filter_args(); WriteMakefile(...); When "WriteMakefile()" is called it parses @ARGV, hoping to find special options like "PREFIX=/home/stas/perl". "Apache::Test" accepts a lot of configuration options of its own. When "Apache::TestMM::filter_args()" is called, it removes any "Apache::Test"-specific options from @ARGV and stores them internally, so when "WriteMakefile()" is called they aren't in @ARGV and thus won't be processed by "WriteMakefile()". The options can be set when Makefile.PL is called: % perl Makefile.PL -apxs /path/to/apxs Or you can push them manually to @ARGV from the code: push @ARGV, '-apxs', $apxs_path; When: Apache::TestMM::generate_script('t/TEST'); is called, "Apache::Test"-specific options extracted by "Apache::TestMM::filter_args()" are written to the autogenerated file. In our example, the autogenerated t/TEST will include: %Apache::TestConfig::Argv = qw(apxs /path/to/apxs); which is going to be used by the "Apache::Test" runtime. The other frequently used options are: "-httpd", telling where to find the httpd (usually when the "-apxs" option is not used), "-libmodperl" to use a specific mod_perl shared object (if your mod_perl is built as DSO), "-maxclients" to change the default number of the configured "MaxClients" directive, "-port" to start the server on a specific port, etc. To get the complete list of available configuration options and their purpose and syntax, run: % perl -MApache::TestConfig -le 'Apache::TestConfig::usage()' You may wish to document some of these in your application's README file, especially the "-apxs" and "-httpd" options. "generate_script" Apache::TestMM::generate_script('t/TEST'); "generate_script()" accepts the name of the script to generate and will look for a template with the same name and suffix .PL. So in our example it'll look for t/TEST.PL. The autogenerated script t/TEST will include the contents of t/TEST.PL, and special directives, including any configuration options passed via "filter_args()" called from Makefile.PL, special fixup code, etc. perl v5.14.2 2011-02-08 Apache::TestMM(3pm)
