[Illustrated] 28 unix/linux command-line artifacts

Below is a collection of 28 unix/linux under the 28 command line tools, some are familiar with, some are very useful, some are not known. These tools are very good, I hope everyone knows. In order to facilitate the study, I have a picture, but also added the official website connection

Dstat & SAR

Iostat, Vmstat, ifstat a triple tool for viewing system performance (I mentioned those three Xxstat tools in the performance tuning strategy).

Screen , Dtach, Tmux, Byobu

Do you often need SSH or telent to telnet to a Linux server? Do you often have headaches for long-running tasks, such as system backups, FTP transmissions, and so on. Usually we open a remote terminal window for each of these tasks because they are running for too long. You must wait for it to finish, during which you can not turn off the window or disconnect, otherwise this task will be killed, all the halfway.

Screen is a window manager that can multiplex a physical terminal across multiple processes. Screen has the concept of a session, where users can create multiple screen windows in a screen session, as in each screens window, as in the case of a real telnet/ssh connection window. See IBM Developerworks's article, "Using screen to manage your remote sessions."

Dtach is a gadget used to simulate screen's detach function, which allows you to freely attach to various sessions. The image below is DTACH+DVTM.



Tmux is an excellent terminal reuse software similar to the GNU screen, but comes from OpenBSD, using BSD authorization. The most intuitive advantage of using it is that after a terminal login to a remote host and run Tmux, it can open multiple consoles without having to "waste" redundant terminals to connect to the remote host; Advantages over screen: The window can be split horizontally and vertically, and the panes can be moved and resized freely.  can be copied and pasted in multiple buffers to support cross window search, abnormal disconnection does not need to detach; It was said that screen was a tmux compared with the other.




Byobu is a tool developed by Ubuntu that is packaged on screen to make it more user-friendly. The newest Byobu is already based on Tmux as the back end. You can control it by accepting a variety of parameters that are identical to the Tmux by using the "Byobu-tmux" command line front-end. The details of the Byobu are very good and the effect is as follows:

Multitail

Multitail is a software that implements the ability to monitor multiple documents simultaneously, similar to tail commands. The difference between him and tail is that he opens multiple windows in the console, making it possible to monitor multiple log documents at the same time. He can also look at log file statistics, merge log files, filter log files, split screen, ...

Xargs & Parallel

Executes tasks from input (even multithread).

Xargs is an older command with a simple parallel function, which is not mentioned. For the GNU parallel (online manpage), it is not only capable of handling multiple threads on the machine, but also distributed to remote computers to assist in processing. Before using the GNU parallel, it is necessary to make sure that there is a GNU Parallel/ssh/rsync installed on the machine, and SSH is installed on the remote computer.





Duplicity & Rsyncrypto

Duplicity is an efficient backup software using the rsync algorithm encryption, duplicity supports directory encryption production and formats upload to remote or local file servers.

Rsyncrypto is rsync + encryption. The algorithm for Rsync can refer to the rsync core algorithm of the cool shell.

Encrypting backup tools.




NetHack & Slash ' em

NetHack (Wiki), 20 years old computer game of history. No sound, no beautiful interface, but the game is really interesting. There's a guy on the internet who says, "If you only do one thing in your life, play NetHack." This sentence is very eye-catching, but also let people think that the game is very complicated not easy to start. In fact, the game is very complex, but easy to get started. Although it's hard to play customs, it's easy to get started. There are many complex rules on NetHack, "The DevTeam Thinks of Everything" (the development team thought of everything). All kinds of monsters, all kinds of weapons ..., there are many spoilers files to illustrate their rules. In addition to the randomly generated maps every time you play a game, you will also encounter strange things: because of drinking a potion to become a robot, because the door to break the store is required to pay a high price; your dog stole the store for you. It's kind of like life, you can't fully understand the world, but you can still choose your own way of facing.

There are many articles on the web that are one of the best computer games or the best computer games. Perhaps because of its open source is appreciated, ancient history is tolerant, complex rules let people awe. Although it is not the current popular game, it is more likely than any current popular game to undergo a 20-year test.

Slash ' EM is also a classic game based on NetHack.




lftp

Use the LFTP command line FTP tool to make incremental backups of your site's data, mirroring, just as with rsync.

Htop & Iotop

Htop and iotop are used to view processes, memory, and IO loads.



Ttyrec & IPBT

Ttyrec is a TTY console recording program whose recorded data files can be played with the accompanying ttyplay. Whether it's a variety of things you do in TTY, or software that you're familiar with in TTY, you can record it.

IPBT is a tool used to back and forth Ttyrec the recording of the console input process.

Similar to this, there are SHELR and Termrec.



rsync

Classic tools for file synchronization via SSH (core algorithm)



mtr

Mtr–traceroute 2.0, a gadget that integrates traceroute with Ping to diagnose the network.




Socat & Netpipes

Socat is a multi-functional network tool, the name is "Socket CAT", can be seen as a netcat n-times enhanced version.

Netpipes, like Socat, is primarily used to command socket operations at the command line, so you can go into the socket network with the shell script.



Iftop & Iptraf

Iftop and Iptraf can be used to view some of the current network link traffic.

Siege & Tsung

Siege is a stress testing and evaluation tool designed for web development that assesses the affordability of applications under pressure: You can configure a Web site for multi-user concurrent access, record the corresponding time for each user's request process, and repeat it under a certain number of concurrent accesses.

rtorrent & Aria2

RTorrent is a very concise, excellent, very lightweight BT client. It uses the ncurses library to write in C + +, so it is completely text-based and runs in the terminal. It is ideal to use rtorrent as a remote BT client on a low-end system with GNU screen and Secure Shell installed.

ARIA2 is the next nice high-speed download tool for Linux. Because it has a segmented download engine, it supports downloading the same file from multiple addresses or multiple connections from one address. This naturally greatly accelerates the download speed of the file. ARIA2 also has a breakpoint continuation function, which allows you to recover a disconnected file download at any time. In addition to supporting the general HTTP (s) and FTP protocols, ARIA2 also supports the BitTorrent protocol. This means that you can also use aria2 to download torrent files.
