Multics was a large multi-user operating system that was being developed at Bell Labs shortly before Unix was created in the early ’70s. Brian Kernighan is credited with the name. All computational genomics is done in Unix http://www.read.seas.harvard.edu/~kohler/class/aosref/ritchie84evolution.pdfMikhail Dozmorov Unix introduction Summer 2018 2 / 37 History of Unix Initial file system, command interpreter (shell), and process management started by Ken Thompson File system and further development from Dennis Ritchie, as well as Doug McIlroy and Joe Ossanna Vast array of simple, dependable tools that each do one simple task Ken Thompson (sitting) and Dennis Ritchie working together at a PDP-11 Mikhail Dozmorov Unix introduction Summer 2018 3 / 37 Philosophy of Unix Vast array of simple, dependable tools Each do one simple task, and do it really well By combining these tools, one can conduct rather sophisticated analyses The Linux help philosophy: “RTFM” (Read the Fine Manual) Mikhail Dozmorov Unix introduction Summer 2018 4 / 37 Know your Unix Unix users spend a lot of time at the command line In Unix, a word is worth a thousand mouse clicks Mikhail Dozmorov Unix introduction Summer 2018 5 / 37 Unix systems Three common types of laptop/desktop operating systems: Windows, Mac, Linux.

    ovs−vlan−test(1) Open vSwitch Manual ovs−vlan−test(1) NAME ovs−vlan−test −check Linux drivers for problems with vlan traffic SYNOPSIS ovs−vlan−test [−s | −−server] control_ip vlan_ip Common options: [−h | −−help][−V | −−version] DESCRIPTION The ovs−vlan−test utility has some limitations, for example, it does not use TCP in its tests. Also it does not takeinto account MTU to detect potential edge cases. Toovercome those limitations a newtool was developed − ovs−test. ovs−test is currently supported only on Debian so, if possible try to use that on instead of ovs−vlan−test. The ovs−vlan−test program may be used to check for problems sending 802.1Q traffic which may occur when running Open vSwitch. These problems can occur when Open vSwitch is used to send 802.1Q traffic through physical interfaces running certain drivers of certain Linux kernel versions. Torun a test, configure Open vSwitch to tag traffic originating from vlan_ip and forward it out the target interface. Then run the ovs−vlan−test in client mode connecting to an ovs−vlan−test server. ovs−vlan−test will display "OK" if it did not detect problems. Some examples of the types of problems that may be encountered are: • When NICs use VLAN stripping on receive theymust pass a pointer to a vlan_group when reporting the stripped tag to the networking core. If no vlan_group is in use then some drivers just drop the extracted tag. Drivers are supposed to only enable stripping if a vlan_group is regis- tered but not all of them do that.

  • Sys, Shutil, and OS Modules
    This video will introduce the sys, shutil, glob, and os modules. 1 The sys module contains a few tools that are often useful and will be used in this course. The first tool is the argv function which allows the script to request a parameter when the script is run. We will use this function in a few weeks when importing scripts into ArcGIS. If a zero is specified for the argv function, then it will return the location of the script on the computer. This can be helpful if the script needs to look for a supplemental file, such as a template, that is located in the same folder as the script. The exit function stops the script when it reach the exit statement. The function can be used to stop a script when a certain condition occurs – such as when a user specifies an invalid parameter. This allows the script to stop gracefully rather than crashing. The exit function is also useful when troubleshooting a script. 2 The shutil module contains tools for moving and deleting files. The copy tool makes a copy of a file in a new location. The copytree tool makes a copy of an entire folder in a new location. The rmtree tool deletes an entire folder. Note that this tool will not send items to the recycling bin and it will not ask for confirmation. The tool will fail if it encounters any file locks in the folder. 3 The os module contains operating system functions – many of which are often useful in a script.

  • ANSWERS ΤΟ EVEN-Numbered
    8 Answers to Even-numbered Exercises 2.1. WhatExplain the following unexpected are result: two ways you can execute a shell script when you do not have execute permission for the file containing the script? Can you execute a shell script if you do not have read permission for the file containing the script? You can give the name of the file containing the script as an argument to the shell (for example, bash scriptfile or tcsh scriptfile, where scriptfile is the name of the file containing the script). Under bash you can give the following command: $ . scriptfile Under both bash and tcsh you can use this command: $ source scriptfile Because the shell must read the commands from the file containing a shell script before it can execute the commands, you must have read permission for the file to execute a shell script. 4.3. AssumeWhat is the purpose ble? you have made the following assignment: $ person=zach Give the output of each of the following commands. a. echo $person zach b. echo '$person' $person c. echo "$person" zach 1 2 6.5. Assumengs. the /home/zach/grants/biblios and /home/zach/biblios directories exist. Specify Zach’s working directory after he executes each sequence of commands. Explain what happens in each case. a. $ pwd /home/zach/grants $ CDPATH=$(pwd) $ cd $ cd biblios After executing the preceding commands, Zach’s working directory is /home/zach/grants/biblios. When CDPATH is set and the working directory is not specified in CDPATH, cd searches the working directory only after it searches the directories specified by CDPATH.
