If you simply want to get to know the installed version of a package or see its description, issue an info command:
$ pear info PEAR About pear.php.net/PEAR-1.7.1 .. more info follows ..
You often don't know which files belong to a certain installed package. list-files is helping you here. It shows you the file's role and its full path:
$ pear list-files log Installed Files For log ======================= Type Install Path doc /usr/share/pear/docs/Log/docs/guide.txt ... php /usr/share/pear/Log/composite.php php /usr/share/pear/Log/console.php ... data /usr/share/pear/data/Log/misc/log.sql test /usr/share/pear/tests/Log/tests/composite.phpt ... php /usr/share/pear/Log.php
While we try to document each package in the manual, many packages - with or without a manual entry - come with examples. They have the file role "doc" and can be located with list-files, too:
$ pear list-files log | grep ^doc doc /usr/share/pear/docs/Log/docs/guide.txt doc /usr/share/pear/docs/Log/examples/composite.php doc /usr/share/pear/docs/Log/examples/console.php doc /usr/share/pear/docs/Log/examples/display.php doc /usr/share/pear/docs/Log/examples/error_log.php doc /usr/share/pear/docs/Log/examples/file.php doc /usr/share/pear/docs/Log/examples/firebug.php ...
list shows you all installed packages with their version and stability:
$ pear list Installed packages, channel pear.php.net: ========================================= Package Version State Archive_Tar 1.3.2 stable Auth 1.5.4 stable Cache 1.5.4 stable Console_Getargs 1.3.4 stable Console_Getopt 1.2.3 stable ...
To see all available packages on the channel server, use remote-list:
$ pear remote-list ... output follows ...
Note: This command takes some time if there are many packages on the server
Instead of going to the PEAR website, you can use the pear installer to search for package names.
$ pear search w3c Retrieving data...0%. Matched packages, channel pear.php.net: ======================================= Package Stable/(Latest) Local Services_W3C_CSSValidator 0.1.0 (alpha) An Object Oriented Interface ...
The result list shows name, remote version and stability and the package description. Alternatively, you can use the package browser on pear.php.net.
