Study notes:

1,%cd% represents the value of the current path

2, for loop of mind can have many kinds of, use different form need to add different parameters:

For example: for/l%variable in (start,interval,end) does command variable (in batch, the use of variables need to appear in a special form%%variable)

Traverse Delete D:\release D:\debug

@echo off for/f "delims="%%a in (' Dir/b/s/ad d:\Release d:\Debug ') do echo rd/s/q "%%a" 2>nul Pause

3, delete the file can use the command del/erase

Delete directory can be rd/rmdir with command

After the plus/s is removed, all of the plus/q expressions are deleted without prompting for deletion.

4, the batch in front of the redirection character can not directly add numbers, you have to use spaces, equal signs, points separated

echo aaaaa.bat >> b.txt means Aaaaa.bat This string is displayed in B.txt

Type Aaaaa.bat >> B.txt indicates that the contents of the Aaaaa.bat are displayed in the B.txt.

5.pause>nul allows the command line to be paused without any display or storage

6 . Batch command if you want to implement the delay between commands and commands , there are several ways to do this:

(1) Using the existing ping command to send the request mechanism to achieve the delay: Ping 127.1-n 5>nul can achieve a 5 second delay in the month

(2, using sleep in VBS to achieve

@echo off

echo Wscript.Sleep wscript.arguments (0) * 1000>delay.vbs

Delay.vbs 2

Del Delay.vbs Echo ok!
