Linux Command Line Basics II: Downloading Data and Controlling Files Yanbin Yin
Linux command line basics II: downloading data and controlling files Yanbin Yin 1 Things you should know about programming Learning programming has to go through the hands-on practice, a lot of practice Hearing what I describe about a command or a program helps, but you will not be able to do it unless you type in the codes and run it to see what happens Reading others’ codes helps but often is harder than writing it by yourself from scratch Although painful and frustrating, trouble-shooting is normal and part of the learning experience (ask experienced people or google) To avoid errors, you have to follow rules; most errors occurred in programming are because of not knowing rules or forgetting rules Use comments in case you forget what you’ve written means write-> run -> errors -> edit-> errors -> ………………………………….. -> run -> success Good news: finished scripts could be reused or edited for later use 2 Homework #7 1. Create a folder under your home called hw7 2. Change directory to hw7 3. Go to NCBI ftp site, find the genome, bacteria, ecoli MG1655 folder, and download the ptt file and the faa file in there 4. Create a copy of the ppt file, if the original file is called A.ptt, name the copied file A.ptt.bak Do the same thing for the faa file 5. Go to https://edu.isb-sib.ch/pluginfile.php/2878/mod_resource/content/4/couselab- html/content.html and finish all quizzes in Chapters 3 to 5. 6. Use what you learned in chapter 5 to count how many protein sequences are in the faa file of step 4. -

Department of Computer Science & Engineering, J.D.I.E.T., Yavatmal, India *Corresponding Author: Email- [email protected] Received: February 21, 2012; Accepted: March 15, 2012 Abstract- First module (FTP) of our framework would provide a user friendly FTP client application which would help even novice user to retrieve the file from remote destination server. Here users fall into two categories: A: Anonymous Users and B: Server Account Holder. In the first category the user can be anyone with no right to update, delete or upload the files on the server thus having limited capabilities. In case of the user having the account he/she has the privilege of writing, reading, update, delete or upload file on to the server. Following implementations would be involved in complete project – Creating a FTP Client Application with all functionalities and capabilities for executing various FTP commands and related functions. Config- uring DNS Server. This application provides a portal to the user through which the user has to specify the keywords along with the frequen- cy. The FTP Client will allow user to download, upload, update, delete and execute various FTP Commands. Keywords- FTP client, FTP server, DNS, TCP/IP Citation: Gampawar A.D., et al.

Getting Started with Unix.Pages
Linux Tutorial Introduction Unix is an “old-school” operating system, developed at Bell Labs in the 1970s — before the mouse, menus, windows, Macs and PCs. Linux is an open-source version of Unix. Under Unix, you communicate with the computer by *typing commands*. This sounds primitive, but it has survived because it lends itself to automation. Typed commands can be put in a text file and executed as a “script”. Unix commands have short names — cd, pwd, ls — to save typing. These names are usually abbreviations: cd = Change Directory, pwd = Print Working Directory, ls = LiSt files. Unix operates under a philosophy of “no news is good news” and “no handholding the user”. You type a command and Unix does it, often silently. You can’t “see” that it did what you asked. If you type “rm *” (DON’T! — this deletes all files in the current folder) Unix complies, without asking “are you sure?”. bash The “shell” is the program you’re using when you’re not using a program. The default shell on our research computers is “bash”. Bash has many commands and features. You can write scripts in bash — short programs that automate repetitive tasks. man Help in Unix is primitive. It is vital to know the names of common commands. If you know the name, you can get help on how to use it by entering “man <command>”. (In these notes, <…> means “replace this with something relevant”.) Within man, spacebar or “ctrl-F” goes forward a page, “ctrl-B” backwards, and “q” quits. Man pages are hard to read. -

Name Syntax Version Description
lftp(1) General Commands Manual lftp(1) NAME lftp − Sophisticated file transfer program SYNTAX lftp [−d][−e cmd][−p port][−u user[,pass]] [site] lftp −f script_file lftp −c commands lftp −−version lftp −−help VERSION This man page documents lftp version 4.8.1. DESCRIPTION lftp is a file transfer program that allows sophisticated FTP,HTTP and other connections to other hosts. If site is specified then lftp will connect to that site otherwise a connection has to be established with the open command. lftp can handle several file access methods - FTP,FTPS, HTTP,HTTPS, HFTP,FISH, SFTP and file (HTTPS and FTPS are only available when lftp is compiled with GNU TLS or OpenSSL library). You can specify the method to use in ‘open URL’command, e.g. ‘open http://www.us.kernel.org/pub/linux’. HFTP is ftp-over-http-proxy protocol. It can be used automatically instead of FTP if ftp:proxy is set to ‘http://proxy[:port]’. Fish is a protocol working overanssh connection to a unix account. SFtp is a protocol implemented in SSH2 as SFTP subsystem. Besides FTP-likeprotocols, lftp has support for BitTorrent protocol as ‘torrent’ command. Seeding is also supported. Every operation in lftp is reliable, that is anynon-fatal error is handled properly and the operation is repeated. So if downloading breaks, it will be restarted from the point automatically.EvenifFTP server does not support the REST command, lftp will try to retrieve the file from the very beginning until the file is transferred completely. lftp has shell-likecommand syntax allowing you to launch several commands in parallel in background (&).
