The cd command without adding arg goes to the home directory. | |cd ..|change directory to ..|Change working directory by going up a directory level.| |ls arg|list|List the contents of arg if this is a directory. Without arg,ls lists the contents of the working directory.| |ll arg|long list|Show detailed information about the arg file.| |ls -a arg|list all|Show all the arg files, even those that start with .., if this is a directory. The ls options can be combined as follows: ls -al.| |chmod [permission type] arg|change mode|Change permissions for the arg file.| |mkdir arg|make directory|Create the arg directory.| |rmdir arg|remove directory|Remove the arg directory if it is empty.| |rm arg|remove|Remove the arg file.| |rm -r arg|remove recursively|Remove arg and all the files which it contains.| |mv arg1 arg2|move|Rename or move arg1 to arg2.| |touch arg|touch|Create an empty file named arg if it does not exist.

Launch a script with a specific version of PHP
To run your scripts from an SSH command, using a specific version of PHP, you have to use specific commands.
|Command|Version| |php.ORIG.4 (cgi)|4.4.9| |php.ORIG.5_2 (cgi)|5.2.17| |php.ORIG.5_3 (cgi-fcgi)|5.3.29| |/usr/local/php5.3/bin/php (cli)|5.3.29| |php.ORIG.5_4 (cgi-fcgi)|5.4.38| |/usr/local/php5.4/bin/php (cli)|5.4.38| |/usr/local/php5.5/bin/php (cli)|5.5.22| |/usr/local/php5.6/bin/php (cli)|5.6.6|
For example, to run the "myScript.php" script with version 5.3 of PHP, you have to run this command:
Before the name of the script you also have to enter its location, For example if your "myScript.php" file is in the "WWW" folder, and you want to run it in version 5.3 of PHP, you have to run this command:
php.ORIG.5_3 www/myScript.php ou php.ORIG.5_3 /www/myScript.php
