BAT file from @ meaning

See a batch of files today, the content is very simple, the implementation is very convenient, learning a bit to know is a DOS command,

It's okay to master a few of these common commands to read someone else's files.

• [email protected] generally followed by similar @echo off

It acts like echo off does not display its command itself (c:\users\xx>), but the echo off global has the effect, @ only the effect on the bank, so the two general, echo on to open echo command line function

• 2.set Name=zhangsan Setting the function of the parameter
• 3.%name% reading the value of a parameter
• 4.set/p name= Please enter a name here Add a/p to represent the need for keyboard input
• 5.pause pause function waits for keyboard input and exits
• 6.echo Book>1.txt > represents writing the file book to 1.txt, overwriting the content (similar to >> it does not overwrite the contents of the output) No output is nul
• 7.set/p Book=<1.txt just input only the first line of the 1.txt copy to book available echo%book% output inspection
• 8.rem is similar to annotations:: No more console output and execution
• 9.: Tab positioning for Goto is very useful

The above several commands are more commonly used, the actual reading is sufficient, the remaining few connection commands feel basically not often
