Common software skills

1. Show row number in Aptana: Right-click the left column and select the row number.

Ii. Install Ubuntu software in/usr/local or/OPT because the/home directory space is not very large.

The downloaded large files are saved under the Windows drive letter/home, which only stores files and documents, so that they can be shared with windows.

 

 

3. Linux mounting prohibited

Sudo gedit/var/lib/polkit-1/localauthority/10-vendor.d/COM. ubuntu. desktop. pkla

Delete the following content.

[Mounting, checking, etc. Of Internal drives]

Identity = Unix-group: Admin

Action = org. freedesktop. udisks. filesystem-*; org. freedesktop. udisks. Drive-Ata-smart *

Resultactive = Yes

 

4. Remove desktop icons

Ubuntu seems to have started to automatically mount the disk since 7.04, but the icons on a disk with more than one desktop are messy. I found the solution today:

Enter at the terminal:

Gconf-Editor

Command to run the configuration editor;

Deselect the volumns_visible option under/apps/Nautilus/desktop.

5. Terminal Color Display

Vi. bashrc

Uncomment # force_color_prompt = Yes, and the terminal will be highlighted!

6. Some shortcut keys

Close Window Alt + F4

Maximize Alt + F10

Run Alt + F2
