Permissions question

1. The problem statement, all variables and given/known data:
Don't understand this problem: The question is the unix command chmod 754 file3 would yield the same permissions as:
I put: chmod u=rwx, g=rx, o=r file3
correct answer was : chmod u+rwx, g=rx, o=r file3

I guess im asking for what does the "+" mean and what the difference to why this is wrong.


2. Relevant commands, code, scripts, algorithms:

chmod


3. The attempts at a solution (include all code and scripts):
test question wrong


4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

FSU, Tallahassee, FL, USA, Prof. Rob, COP 3353

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)
