title: 7z

|

|

<p>
|
||||
A .7z. file is an archive format that stands for 7-zip. By default, Mac OS X does not know how to handle these files, but that is not a big deal because you can download for free in App Store. The program supports 7z, ZIP, CAB, ARJ, BZIP2, TAR, CPIO, RPM and DEB.<br>
|
||||
|
||||
So, first of all, you need to download Unarchiver in order to use this command.<br>
|
||||
|
||||
The basic syntax is:
|
||||
</p>
|
||||
|
||||
<pre>
|

7z [adeltux] [-] [SWITCH] <code><ARCHIVE_NAME> <ARGUMENTS></code>

<h1>-m (Set compression Method)</h1>
|

|

|

|
||||
<h1>-r (Recurse subdirectories) switch</h1>
|
||||
|
||||
<p>Specifies the method of treating filenames or wildcards on the command line.</p>
|
||||
The syntax:
|
||||
|
||||
<pre>
|
||||
-r[- | 0]
|
||||
</pre>
|
||||
|

|

|
||||
<tr>
|
||||
<td> -r0 </td>
|

<td> Enable recurse subdirectories only for wildcard names </td>
|

</tr>
|

</table>
|
||||
|

<p>
|
||||
If we want to list all *.doc files that belong to the archived root directory in the <i>archive.zip</i> archive, we can do as follows:
|
||||
</p>
|
||||
|
||||
<pre>
|
||||
7z l archive.zip *.doc -r-
|
||||
</pre>
|
||||
|
||||
<h1>-p (Set password) switch</h1>
|
||||
|
||||
<p>Specifies a password</p>
|
||||
Here the syntax is very simple:
|
||||
|
||||
<pre>
|
||||
-p{password}
|
||||
</pre>
|
||||
|
||||
If we want to protect some files we can compress for example all *.txt files to archive.7z using a password as "cimbale".
|
||||
|
||||
<pre>
|
||||
7z a archive.7z -pcimbale
|
||||
</pre>
|
||||
|
||||
Then if we want to extracts all files from archive.7z we need the password "cimbale".
|
||||
|
||||
<pre>
|
||||
7z x archive.7z -pcimbale
|
||||
</pre>
|
||||
|
||||
<h1> -x (Exclude filenames) switch </h1>
|
||||
|
||||
<p>
|
||||
Specifes which filenames or wildcards must be excluded from the operation.
|
||||
</p>
|
||||
Syntax:
|
||||
|
||||
<pre>
|
||||
-x[<recurse_type>]<file_ref>
|
||||
</pre>
|
||||
|
||||
Sometimes we need to add files into an archive.7z, except one, this can be done as fllows:
|
||||
|
||||
<pre>
|
||||
7z a -tzip archive.7z *.txt -x!temp.*
|
||||
</pre>
|
||||
