[Arrangement] Linux FTP client lftp usage

1. In one breath
$ Lftp (ftp: //) User: password @ site: Port
It is usually used for the off-the-shelf links provided on web pages or BBs. The disadvantage is that the password is displayed as a plain text. We recommend that you input it in a dark environment without any one.
$ Lftp (ftp: //) user @ site: Port
Then the system will prompt you to enter the password, which is ***

2. Regular Expression

$ Lftp site-P port-u user, password
This is the standard method provided in the lftp instruction document. This method is labor-intensive. Please do your best according to your health condition. If the physical fitness is normal, you can
$ Lftp site: Port-u user, password
It seems a little easier. I usually use this method.

3. Hide a length in the five short periods

This is a method for Recursive nesting #@! × &
$ Lftp
Lftp: ~> Lftp User: password @ site: Port
That is to say, the operations on the lftp console are exactly the same as those on the system terminal. You can still use the first two tricks with no scruples, or use o or open instead of lftp, you can also enter the format of the user name and password of the Website Based on your preference.

4. Ultimate Success

Every time I log on, I have been hitting a user: password @ site: port for a long time. Even if Li tie is here, I cannot help myself. Therefore, we still need to let lftp write down frequently-used sites, just like the platform manager in flashfxp, which is called bookmark in lftp. Let's talk about it later.

The first thing to do is to check what is good on this server. The operation is the same as in the terminal. ls is used to list the server directories. One thing to note is that after the first ls operation, the directory table is saved to the local cache, so that the latest list under this directory cannot be obtained after the LS operation. In this case, you can use rels to download the directory table again. Here, the cache is the default setting of lftp. The purpose is to get a list faster, but sometimes it does not match your usage habits. You can use cache on and cache off to switch the cache, or use cache flush to clear the cache. There is nothing to say about changing the directory. lftp also supports the tab matching function, greatly reducing the labor intensity.

Lftp supports six modes: FTP, ftps, HTTP, https, hftp, fish and file (of course, https and ftps support must be compiled together with OpenSSL library ).

Lftp has built-in shell-like command format, allowing multiple commands (&) to be executed at the same time in the background (&). All background tasks are executed in the same program (process). commands that can be run in the foreground can be executed in the background (CTRL-Z ), or get back the foreground execution (wait or fg) from the background, or even determine whether to execute the current command (& |) through the return value of the previous command ).

At the end of lftp, if a program is still running, lftp will switch itself to the No hup mode and put it in the background for execution. Therefore, you do not have to worry about the failure to log out during lftp execution.

!
Execute commands in the local shell, such! Ls/usr/local/bin/Since lftp does not have LLS (commands for displaying the local file list), it is available! Ls.

Alias []
Define aliases
Alias less more
Alias reconnect "close; CD ."
Enter alias directly to see the aliases currently defined. If you only enter alias name, the alias name is canceled.

Bookmark subcmd
Set the book category. You can set the current platform and directory as a book category. Next time you can directly come in without CD.

Bookmark Add name is used to add a book named name
Bookmark del name: delete a book named name
The bookmark list shows that there are currently set the book lists (In addition, the results of directly typing bookmark and bookmark list are the same)
Bookmark edit call Editor (~ /. Lftp/bookmarks)

Rels []
Display the remote file list from the cache
Rels will not read from the cache

Recls will not read from the cache

Get opts-o
Capture remote files

Get rfile-O lfile
Capture rfile and rename it lfile

LCD
Switch the local directory

Mirror opts remote [local]

-C resume
-E be careful when comparing remote and local files. If the remote files do not exist, delete the local files, that is, synchronize the local and remote data.

-N: only download newer files
-R does not need to be handed over to the directory.
-- Parallel = N simultaneously downloads n files (only one file is downloaded at a time by default)

History-W file-r file-c |-l CNT
Like history in bash

Renlist []

PWD-P
Displays the current remote directory
-P: the logon password is displayed.

Scache []

Switch between directories on multiple platforms or on the same platform at the same time.

The younger brother has met some platforms, and an IP address is only allowed to log on once. If he wants to keep a large number of files under different directories at the same time, he can only capture one file at a time, after the command is finished, you can switch to another directory to capture the second one. Then, the queue of lftp will be used. Generally, if get and mget are used, the file will be downloaded directly, and the file cannot be switched to another directory. Therefore, stop the queue first, and then press Enter, next job, we can see that the current queue is stopped. Then add the stuff to the queue one by one, and wait until the stuff to be captured enters
After the queue, start the queue and send it all at once. This saves you the trouble of checking whether the file is fully captured at any time.

/Etc/lftp. conf
The actual location of the global configuration file depends on the directory of the system configuration file, which may be in/etc or/usr/local/ET.
C

~ /. Lftp/RC ,~ /. Lftprc
The user configuration file will be executed after/etc/lftp. conf, so the above settings will overwrite the settings in/etc/lftp. conf.
By default, lftp does not display the FTP server's welcome information and error information, which is inconvenient in many cases, because you may want to know whether the server is unable to connect to the server because it is not powered on or the number of connections is full. If so, you can ~ /. Write a row in lftprc

Debug 3

The error message is displayed.
For more configuration options, see the man manual or use the set-a command on the lftp interface.

~ /. Lftp/log
When lftp is switched to the background non-suspended mode for execution, the output will be redirected here

~ /. Lftp/bookmarks
This is where lftp stores bookmarks. You can use lftp to view the bookmark command.

This file is used to store the working directory of the accessed site

When a problem occurs in displaying the Chinese character set, the charset of the remote FTP server is gb2312. If I directly use ls, all Chinese characters are garbled and there is no way to use it. Just give a parameter like this:

Lftp ryun@www.example.com:/> set ftp: charset gb2312

Then, let's take a look at ls to see if it's more friendly. ^____ ^

There is also a way to set the configuration file for friends who frequently use the Chinese Character Set ftp:

Touch ~ /. Lftp/RC
Echo 'debug 4'> ~ /. Lftp/RC
Echo 'set ftp: charset gbk'> ~ /. Lftp/RC

Now, lftp supports displaying Chinese characters directly.

Unable to connect in passive mode, you can column the directory after converting to active mode: After logging on to lftp, execute:
