Two. Mac OSX command line:

1. List files
LS parameter catalog name: see what's in the drive directory: ls/system/library/extensions
Parameter-W displays Chinese,-l details,-a including hidden files
2. Conversion directory
CD Example: Think of a drive directory to stroll around Cd/system/library/extensions
3. Create a new catalogue
mkdir Directory Name Example: Build a backup directory under the driver directory backup Mkdir/system/library/extensions/backup

4. Copy files
CP parameter source file target file example: Want to copy the desktop Natit.kext to the driver directory cp-r/user/user name/desktop/natit.kext/system/library/extensions
The parameter R indicates a recursive operation of the directory, and Kext looks like a file under the graphical interface, which is actually a folder.
Back up all files in the drive directory to desktop backup
Cp-r/system/library/extensions/*/user/User name/desktop/backup
5. Delete Files
RM Parameter File example: Want to delete the driver's cache Rm-rf/system/library/extensions.kextcache Rm-rf/system/library/extensions.mkext
Parameter-RF is recursive and mandatory, be careful to use, if executed RM-RF/your system is gone

Want to move the Applehda.kext to the backup directory Mv/system/library/extensions/applehda.kext/system/library/extensions/backup
7. Text editing
Nano File name example: Edit Natit info.plist nano/system/library/extensions/natit.kext/info.plist
Directory Operations:

Mac Delete all the. svn files in the folder
Directly inside the terminal, execute the command (it seems that the directory name cannot contain spaces):
sudo find/users/cundong/documents/source-name ". SVN"-exec rm-r {} \;
Get the files out of the phone.
ADB pull/sdcard/360download/source.apk/users/cundong/desktop/target.apk

2). Download Dex2jar http://code.google.com/p/dex2jar/
Extract
Give permission chmod +x dex2jar.sh
Run./dex2jar.sh/users/cundong/desktop/xxxx.apk
3). Download Jd-gui can be opened directly to see. http://java.decompiler.free.fr/

--------------------mac Common Commands--------------------

Apple Mac OS X operating system, hidden files are shown there are many ways to set, the simplest to count on the Mac Terminal Input command. The show/Hide Mac hidden files command is as follows (note the spaces and case-sensitive):
command to display Mac hidden files: Defaults write Com.apple.finder appleshowallfiles-bool true
command to hide Mac hidden files: Defaults write Com.apple.finder Appleshowallfiles-bool false
Or
command to display Mac hidden files: Defaults write Com.apple.finder appleshowallfiles YES
command to hide Mac hidden files: Defaults write Com.apple.finder appleshowallfiles NO
After you lose, click Enter, exit the terminal, and restart the finder.
Restart Finder: Mouse click the Apple flag in the upper-left corner of the window and force exit-->finder--> restart

Mac OS X terminal shortcut key: cammand+k (Clear actually no bird)
Linux system Clear Screen shortcut key: ctrl+l (reset)
Windows command line Clear command: CLS
OS X uses UNIX file systems, all files are hung in the root directory/below, so there is no longer a drive letter concept under Windows.
The hard drives you see on the desktop are hung under/volumes.
For example, after a mobile drive called USBHD, the desktop will show a hard disk icon, where is it actually?
Execute LS/VOLUMES/USBHD in the terminal to see if the contents of this mobile drive are displayed.
root directory location is/core Mach_kernel right here,
Drive Location/systme/library/extensions
User folder location/user/user name
The location of the desktop/user/user name/desktop

File wildcard character Asterisk *
Note: In UNIX systems, there is a difference between uppercase and lowercase characters, and A.txt is not equal to a.txt.
Root flag/Not dispensable, cd/system means to go to the system under the directory, and the CD system means to go to the system in the current directory

How to enter command line operation mode
In the graphical interface, open the Application utility terminal with the Finder
If even the graphical interface can not be entered (such as the wrong display driver), when the boot press F8, start with the-s parameter, and then enter the command MOUNT-UW/
Get permission
In order to prevent misoperation to destroy the system, then the user state when there is no permission operating system important files, so first to get root permissions
Sudo-s
Then enter the password, enter the password without any echo, even the asterisk is not, just lose the return on the line.
——————————————————————————————————————————————
List files
LS parameter directory name
Example: Want to see what is in the directory,
LS/
Want to see what's in the drive directory,
Ls/system/library/extensions
Parameter-W displays Chinese,-l details,-a including hidden files
Converting catalogs
Cd
Example: Think of a drive directory to stroll around
Cd/system/library/extensions
Create a new directory
mkdir Directory Name
Example: Create a backup directory in the driver directory
Mkdir/system/library/extensions/backup
Build a backup directory on the desktop back up
mkdir/user/User name/desktop/backup

Copy files
CP parameter source file destination file
Example: Want to copy the desktop Natit.kext to the drive directory
Cp-r/user/User Name/desktop/natit.kext/system/library/extensions
The parameter R indicates a recursive operation of the directory, and Kext looks like a file under the graphical interface, which is actually a folder.
Back up all files in the drive directory to desktop backup
Cp-r/system/library/extensions/*/user/User name/desktop/backup

deleting files
RM parameter file (RM-RF folder)
Example: To delete a driver's cache
Rm-rf/system/library/extensions.kextcache
Rm-rf/system/library/extensions.mkext
Parameter-RF is recursive and mandatory, be careful to use, if executed RM-RF/your system is gone

Moving files
MV File
Example: Want to move Applehda.kext to the desktop
mv/system/library/extensions/applehda.kext/user/User name/desktop
Want to move the Applehda.kext to the backup directory
Mv/system/library/extensions/applehda.kext/system/library/extensions/backup

Change file permissions
chmod parameter permission file (#add ch represents change)
Example: Set all files in the drive directory to root read/write, other users read only
Chmod-r 755/system/library/extensions
The parameter R is recursive, and 755 represents the permissions of each user

Change file Owner
Chown parameter User: Group file
Example: Change all the files in the drive directory to the root user
Chown-r root:wheel/system/library/extensions
Parameter r indicates a recursive operation

Fix permissions on files throughout the system
Diskutil repairpermissions/
Strictly speaking, this is not a Unix command, but OSX is a software that remembers the modification or addition of the driver to execute once.
Text editing
Nano file name
Example: Edit Natit info.plist
Nano/system/library/extensions/natit.kext/info.plist
After editing, use Ctrl +o to save, ctrl+x exit
Another text editing software is VI, the operation is a bit odd, cooked is very useful, and in all Unix-like systems, it is not afraid to go all over the world.
Run script command
SH Script file name
Example to modify the driver after all the required operations into a script, after the driver has been modified to run once this script is OK, convenient
1. Running Nano/clean in terminal
2. Paste the following code into the nano
Rm-rf/system/library/extensions.kextcache
Rm-rf/system/library/extensions.mkext
Chown-r root:wheel/system/library/extensions
Chmod-r 755/system/library/extensions
Diskutil repairpermissions/
Kextcache-k/system/library/extensions/
3. Ctrl +o disk, ctrl+x exit
4. Once the driver is moved, run it once in the terminal Sh/clean
————————————————————————————————————
Little Tricks
Use the Tab key to auto-complement commands
For example, think of the/system directory, enter the Cd/sy and then press the TAB key, the command will automatically fill into equal Cd/system
Manipulate files and directories with spaces in the name
Spaces are written in the command, for example, to enter My Documents, the command is CD My Documents
View detailed help for a command
Man command name (#add manual)
For example, to see the detailed use of the LS command, execute the man ls

Typical Operating Procedures
Suppose you download a video card driver Natit.zip, the desktop decompression to get a natit.kext, how to do it?
For the sake of insurance, back up all the drivers first.
mkdir/user/User name/desktop/backup Create a backup folder on the desktop
Cp-r/system/library/extensions/*/user/User name/desktop/backup backup driver file
Now you can install it safely.
Cp-r/user/user name/desktop/natit.kext/system/library/extensions copy it to the system-driven directory location
Sh/clean Execute cleanup Script, Operation complete
Re-boot failed, into the desktop, found that should not be the driver, how to recover it?
Power on F8, start with-s parameter
Execute MOUNT-UW/
rm-rf/user/User name/desktop/natit.kext Delete this driver
Sh/clean Execute cleanup Script, Operation complete
Restart, back to the original state, do not forget Ah, no special effects how to do it, and heard the need to modify the Natit Info. plist file is fine.
Cp-r/user/user name/desktop/natit.kext/system/library/extensions copy it to the system-driven directory location
Nano/system/library/extensions/natit.kext/info.plist
After editing, use Ctrl +o to save, ctrl+x exit
Sh/clean Execute cleanup Script, Operation complete

Restart, this time, the Carter effect has been, the sound card, God knows what will happen, we have to protect the existing results.
mkdir/user/User name/desktop/gooddrivers to create a directory for valid drivers
Cp-r/system/library/extensions/natit.kext/user/user name/desktop/gooddrivers backup
This sound card requires Applehda.kext to delete and edit the Appleazaliaaudio.kext in the Info.plist file, who knows later will not still use AppleHDA it, rather temporarily disable it.
mkdir/system/library/extensions/disabled Creating a disabled directory
Mv/system/library/extensions/applehda.kext/system/library/extensions/disabled move Past
Nano/system/library/extensions/natit.kext/appleazaliaaudio.kext/info.plist
After editing, use Ctrl +o to save, ctrl+x exit
Sh/clean Execute cleanup Script, Operation complete
Successful, also the modified driver back up the copy content to the Clipboard code:
