Technically it's all "geek" to you Smilie

Anyway, you should be able to man chmod to see what's going on. Quickly though.

-R - recursive, all files/directories under the directory identified will be modified
a - All three octets (user, group, and world perms) will be modified
+r - Add read access
. - file/directory to be modified

So the first command says to add read access to all users for all files in the current directory and all subdirectories

The second command is already mostly explained.

+w - Add write access
logo.gif tempdir/ templates_c/ - files/directories to be modified

The reason you'd use this format is that you don't want to modify any subdirectories or files other than the read and/or write access bits.

PHARFILEINFO.CHMOD(3)							 1						     PHARFILEINFO.CHMOD(3)

PharFileInfo::chmod - Sets file-specific permission bits

SYNOPSIS
public void PharFileInfo::chmod (int $permissions) DESCRIPTION
PharFileInfo.chmod(3) allows setting of the executable file permissions bit, as well as read-only bits. Writeable bits are ignored, and set at runtime based on the phar.readonly INI variable. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed if the file is within a Phar archive. Files within PharData archives do not have this restriction. PARAMETERS
o $permissions - permissions (see chmod(3)) RETURN VALUES
No value is returned. EXAMPLES
Example #1 A PharFileInfo.chmod(3) example <?php // make sure it doesn't exist @unlink('brandnewphar.phar'); try { $p = new Phar('brandnewphar.phar', 0, 'brandnewphar.phar'); $p['file.sh'] = '#!/usr/local/lib/php <?php echo "hi"; ?>'; // set executable bit $p['file.sh']->chmod(0555); var_dump($p['file.sh']->isExecutable()); } catch (Exception $e) { echo 'Could not create/modify phar: ', $e; } ?> The above example will output: bool(true) PHP Documentation Group PHARFILEINFO.CHMOD(3)
