Basic commands for Linux and win

1, Print working directory: PWD

(That is, your main work environment, such as in the Cygwin input pwd, the reality is/home/administrator)

Win is the same as Linux

2. Print Computer name: hostname

3, create a directory: mkdir

The difference between Linux and win is when you create a table of contents,

The operation of Linux is Mkdir-p Temp/stuff/things/john

The operation of Win is mkdir Temp/stuff/things/john

4, change the directory (personal feeling should be called Open Directory): CD

CD temp/stuff/things

Cd.. /.. /.. /(two points for one level)

5. List contents: ls

6, delete the path, directory: RmDir

7, pushd push into the path, such as in a directory can be directly pushd to other directories (belonging to temporary access, convenient exchange)

8, popd roll back to the push before the directory

Attention:

The pushd command will "push" your current directory to a list for later use, and then let you move to another directory. It

"Remember my present position and go to this place," said the general. ”

The popd command will "pop up" the list of your last push, and then let you return to the "pop-up" directory.

9. Create an empty file:

Under Linux is: Touch

Under Win is: New-item iamcool.txt-type file

10, copy the file:

Under Linux:

In a directory wash replication aaa.txt CP aaa.txt Bbb.txt

Copy a file area another folder content CP Aaa.txt bbb/

In the same directory, copied from one directory to another, cp-r BBB (directory name) newb (new directory name) "Copy the past is the BBB directory under the file name." 】

The last difference under win is to change R to Recurse

11, move the file or say rename: MV

Linux: Renaming files mv Aaa.txt BBB.TXT,MV Triple A BBB

Win under: Same

12, view the contents of the file:

linux:less filename, q exit

Win:more file name

13, flow-style content display, that is, open the file cat:

Linux:cat Baidu.log

WIN: Same

14, delete files: RM

LINUX:RM file name multiple files rm aaa.txt Bbb.txt

Win: Unlike Linux, it is necessary to delete multiple files by one by one.

The cycle of deletion should be careful, the circular deletion is rm-r something

15. Pipelines and redirects:

Linux:

| Directs the output of the left-hand command to the zip command;

< send the right file as input to the program on the left > write the output of the left command to the file on the right

>> append the output of the left command to the file on the right

Win:

"I don't know".

16, wildcard character matching: *

Linux: matches any character

Win: Same

17, looking for documents: find

Under Linux: Find. -name "*.txt"-print "find, filename, and print"

Win under: Dir-r such as: Dir-r-filter "*.txt"

18, File Find content: grep,select-string

Linux: Directly write content cat > Aaa.txt keyboard ctrl+d Close, find words, use grep name (feature), such as new *. txt

Win: Directly write the content echo > Aaa.txt keyboard ctrl+d off. Use select-string lookup, such as select-string new *.txt

"Note": Grep-i ignores case

19, the command line Help (MAN,HELP)

Linux:man such as: Mans grep

Win:help such as: Help Dir/help CP

20. Looking for help (apropos, helps)

Linux Apropos is not available

Win is based on help to add * such as, help *remove*

21. Environment variable (env,echo,env:)

Print out existing environment variables

Under Linux is env

Win under IS Get-childitem env

22. Modify Environment Variables:

Get-childitem ENV:

23, leave the command line

Linux Exit,win like
