Few commands that can save your time

Here i am listing few commands that i am using. I am sure it will be helpful.

1. Create UML from PHP code. ( annoying and little bit hacky but works well :P) 

• sudo phpuml ~/shiksha/trunk/LDB/controller/LDB_Server.php -f htmlnew -o ~/Desktop/ -x 1 -n ldb -m *.php6 -i .svn
• sudo phpuml ~/shiksha/trunk/CodeIgniter/ -o ~/Desktop/ -x 1 -n Foo -m *.php6 -i .svn

2. VIM coomands

• zz save and exit
• ? search backword
• p command for paste
• ma mark then can use "d'a" to delte entire
• y for copy [can do same y'a or yy ]
• :split to open other file
• CTRL ww to jump file
• > move to right
• ZZ save and exit
• ZQ exit without save
• :tabs - View a list of tabs that are open with the file names. Use the command ':tabs' and Vim will display a list of all the files in the tabs. The current window is shown by a ">" and a "+" is shown for any modifiable buffers.
• :tabc - Close the current tab.
• :tabnew - Open a new file for editing in a separate tab.
• :tab split - Open the file in the current buffer in a new tab page.
• :tabn - Switching to the next tab page.
• :tabp - Switch to the previous tab page.
• :tabr[ewind] - Go to the first tab page. You get the same effect when you use the :tabf[irst] command.
• :tabo - Close all other tab pages.

3. PHP Codebase Reports
