FTP Command Set

FTP commands are one of the most frequently used commands by Internet users. Familiarizing and flexibly applying FTP internal commands can greatly facilitate users and achieve twice the result with half the effort.

If you want to learn to use background FTP download, then you must learn FTP commands.

The command line format of FTP is: ftp -v -d -i -n -g ,

where -v displays all response information of the remote server;

-n restricts automatic login of ftp, that is, does not use the.netrc file;

-d uses the debugging mode;

-g cancels global file names.

The internal commands used by FTP are as follows (brackets indicate optional items):

Is it the one in the "DOS Articles" section?

Some internal commands have been added ^_^

Oh. In the future, please produce more technical articles.

Hope that experts can post more examples so that newcomers can learn!

Very valuable

Let me let out a coarse word: Damn, I forgot this command, I'm angry, I regret, I destroy

Thanks to the LZ, I've learned.

steersman is right. When giving commands, add a few more examples. Novices can easily understand, grasp, and learn.

Very useful!
