wildcards in "if then" statement
Hello,

I would like to use a simple "if then" test to check if an argument to a command begins with "http://" as follows:

if [ $2 == http://* ]; then

command
fi

but the wildcard just seems to be ignored, ie., it will only execute the command if the expression is strictly "http://" with nothing following it. I have tried enclosing the second expression with single and double quotes, and have tried using various wildcards such as ".", "?", ".*", etc. to no avail.

Any suggestions?

Thank you,

Allasso Travesser

YUM-VERSIONLOCK(1)						   User Manuals 						YUM-VERSIONLOCK(1)

NAME

       yum-versionlock - Version lock rpm packages

SYNOPSIS

       yum-versionlock [ package-name [ package-name]] ...

DESCRIPTION

       yum-versionlock(1)  is  a  Yum  plugin  that  takes  a  set of name/versions for packages and excludes all other versions of those packages
       (including optionally following obsoletes).  This allows you to protect packages from being updated by newer versions.

       The plugin provides a command "versionlock" which allows you to view and edit the list of locked packages easily.
	yum versionlock add <package-wildcard>...

       Add a versionlock for all of the packages in the rpmdb matching the given wildcards.   yum versionlock exclude <package-wildcard>...

       Add a exclude (within versionlock) for the latest versions of the packages in the available repos. matching the given wildcards.   yum ver-
       sionlock list

       List the current versionlock entries.   yum versionlock delete <entry-wildcard>...

       Remove any matching versionlock entries.   yum versionlock clear

       Remove all versionlock entries.

FILES

       /etc/yum/pluginconf.d/versionlock.conf
	      The system wide configuration file. See yum-versionlock.conf(5) for more information.
       /etc/yum/pluginconf.d/versionlock.list
	      The default place to put package version lock information (one package and version per. line). The file takes entries in the follow-
	      ing format EPOCH:NAME-VERSION-RELEASE.ARCH See rpm(8) for more information on custom query formats. If the package does not have	an
	      EPOCH the number will default to 0.

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
