Introduction to the Linux Command Line. Sabry Razick (RCS Nov 2015) What Is a Terminal Introduction to the Linux command line. Sabry Razick (RCS Nov 2015) What is a terminal ● The terminal is an interface in which you can type and execute text based commands. ● It can be much faster to complete some tasks using a Terminal than with graphical applications and menus. ● Allowing access to many more commands and scripts. ● When making your own program, it is easier and faster to design it to work on the terminal than with the mouse. ● More transparency on what is going on ● More control on what you do ● ……. How to access the terminal ● Unix based systems (Redhat, Ubuntu….Mac OS) it is there as a program already. ● Windows - Windows command line (cmd) can not do the thing Unix terminal do. So you need a Virtual environment or get access a Unix machine ● Virtual environment ○ Oracle Virtual Machine - www.oracle.com/us/technologies/virtualization/oraclevm/ ○ Cygwin - https://www.cygwin.com/ ○ Boot with a live CD/Falsh drive ● Access a Unix machine ○ Putty - http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html Windows ● abel.uio.no ● freebee.abel.uio.no ● Use UIO username and password Unix ● Locate the terminal The shell ● Shell provides an interface between you and the operating system of the computer ● Use the keyboard to tell the computer what you want of it ● Where is my home ○ echo $HOME ● Go to my home ○ cd $HOME ● What files or folders have in my home ○ ls ● Give me more details about the files ○ ls -lh The shell ● Find out more about a command ○ man <COMMAND> ○ e.g. man ls ● List them in sorted ○ ls -lhrt (list oldest first) ○ ls -lh --sort=size ● Set permissions ○ chmod a+r test.txt ○ chmod g+r test.txt ○ chmod u+x test.txt ○ chmod +x test.txt The shell ● Create a directory ○ mkdir rcs2015 ● Changed to that directory ○ cd rcs2015 ● I am not sure where I am ○ pwd ● Create file ○ touch test.txt ○ echo “some text” > test2.txt ○ nano test3.txt (Ctrl + o -- Save, Ctrl -x to get out) ● list the files that ends with txt ○ ls -lh *txt Path ● Path specifies a position in the directory tree. There are two kinds of paths. ○ absolute ○ relative ● Absolute path always starts at at the top of the tree (at the root directory), for example “/home/username”. The absolute path always starts with a “/” (root). ● The relative path is the path to the destination from your current position and it does not start with a “/”. The shell ● Delete a file ○ rm test2.txt ● Delete a directory ○ mkdir tmp ○ rm -r tmp ○ tmdir tmp ● Create another directory and copy the file test.txt ○ mkdir $HOME/rcs2 ○ cp test.txt $HOME/rcs2 ○ cd $HOME/rcs2 ○ cp ../rcs2/test.txt . ○ cp <FULLPATH>/test.txt <FULLPTH>/ ● Move a file (keep the copy delete the original, rename) ○ mv test2.txt mv test_new.txt The shell ● Which machine am I in ○ hostname ● Who else is logged in ○ who ● How am I logged in ○ who am i ● What are the things running at the moment ○ top ● What are the thing I am running ○ top -u <USER_NAME> ● Do I have internet connection ○ ping uio.no FIles ● Create a new file and add a content ○ nano filetest.txt ○ AAAACCTTGCCGGTCCC… ○ Ctrl + o, Ctrl +x ● Display the content ○ less filetest.txt ○ less filetest.txt | more ○ cat filetest.txt ● Find whether there is a specific string in the file ○ grep “AA” filestest.txt ● Find out the file with the name filetest.txt ○ cd .. ○ find -name filetest.txt Files ● Find the file containing the string AAA, look everywhere starting from current directory ○ grep -Rni “AA” ○ grep -RH --include='*txt "AA" . ● Peak ○ head test.txt ○ tail test.txt ● nano table.txt A B C D E A1 B1 C1 D1 E1 A2 B2 C2 D2 E2 A2 B3 C2 D3 E3 A4 B4 C2 D4 E4 awk , sort, uniq , tr ● Print the first column ○ awk '{print $1}' table.txt ● Create a new file by shifting column one and two ○ awk '{print $2"\t"$1"\t"$3"\t"$4}' table.txt > table2.txt ● Display unique values on first column ○ cat table.txt |awk '{print $1}'| sort | uniq ● Collapse raws ○ tr '\n' ';' < emails.txt Programs ● Where the program is installed ○ which ls ● Create a small program ○ echo "hi \$1" > p1.sh ● Make it executable ○ chmod +x p1.sh ● Run it ○ ./p1.sh AAA ● Add it to path so you can run it from anywhere ○ echo $PATH ○ export PATH=$PATH:$HOME/rcs2015/ Extra ● sed ○ sed -n '2,3p' table.txt ● Processes ○ ps -ef | grep bash ● Replace a string in a file (no undo !) ○ find . -type f -name "3.txt*" -exec sed -i "s/A/B/g" {} + Extract 2 columns and join them with a dot.

    at—at, batch—execute commands at a later time at [–csm] [–f script] [–qqueue] time [date] [+ increment] at –l [ job...] at –r job... batch at and batch read commands from standard input to be executed at a later time. at allows you to specify when the commands should be executed, while jobs queued with batch will execute when system load level permits. Executes commands read from stdin or a file at some later time. Unless redirected, the output is mailed to the user.

Typing test will be conducted on computer. 2. Persons with benchmark disability in the category of Visually impaired, orthopedically handicapped (afflicted by cerebral palsy), orthopedically handicapped (both arm affected), orthopedically handicapped candidates who has a locomotor disability wherein the dominant writing extremity is affected to the extent of slowing down the performance of the candidate (such deficiency to be indicated in the certificate, issued by competent authority, submitted by the candidate) will be allowed compensatory time of 05 minutes. 3. VI Candidates are eligible for scribe/passage dictator. 4. The Scribe/ Passage dictator is identified by the candidate at own cost and as per own choice. 5.

    job monitor and control top: similar to windows task manager (space to refresh, q to exit) w: who is there ps: all running processes, PID, status, type ps -ef | grep yyin bg: move current process to background fg: move current process to foreground jobs: list running and suspended processes kill: kill processes kill pid (could find out using top or ps) 1 sort, cut, uniq, join, paste, sed, grep, awk, wc, diff, comm, cat All types of bioinformatics sequence analyses are essentially text processing. Unix Shell has the above commands that are very useful for processing texts and also allows the output from one command to be passed to another command as input using pipe (“|”). less cosmicRaw.txt | cut -f2,3,4,5,8,13 | awk '$5==22' | cut -f1 | sort -u | wc This makes the processing of files using Shell very convenient and very powerful: you do not need to write output to intermediate files or load all data into the memory. For example, combining different Unix commands for text processing is like passing an item through a manufacturing pipeline when you only care about the final product 2 Hands on example 1: cosmic mutation data - Go to UCSC genome browser website: http://genome.ucsc.edu/ - On the left, find the Downloads link - Click on Human - Click on Annotation database - Ctrl+f and then search “cosmic” - On “cosmic.txt.gz” right-click -> copy link address - Go to the terminal and wget the above link (middle click or Shift+Insert to paste what you copied) - Similarly, download the “cosmicRaw.txt.gz” file - Under your home, create a folder
