CS101 Lecture 9
How do you copy/move/rename/remove files? How do you create a directory ? What is redirection and piping? Readings: See CCSO’s Unix pages and 9-2 cp option file1 file2 First Version cp file1 file2 file3 … dirname Second Version This is one version of the cp command. file2 is created and the contents of file1 are copied into file2. If file2 already exits, it This version copies the files file1, file2, file3,… into the directory will be replaced with a new one. dirname. where option is -i Protects you from overwriting an existing file by asking you for a yes or no before it copies a file with an existing name. -r Can be used to copy directories and all their contents into a new directory 9-3 9-4 cs101 jsmith cs101 jsmith pwd data data mp1 pwd mp1 {FILES: mp1_data.m, mp1.m } {FILES: mp1_data.m, mp1.m } Copy the file named mp1_data.m from the cs101/data Copy the file named mp1_data.m from the cs101/data directory into the pwd. directory into the mp1 directory. > cp ~cs101/data/mp1_data.m . > cp ~cs101/data/mp1_data.m mp1 The (.) dot means “here”, that is, your pwd. 9-5 The (.) dot means “here”, that is, your pwd. 9-6 Example: To create a new directory named “temp” and to copy mv option file1 file2 First Version the contents of an existing directory named mp1 into temp, This is one version of the mv command. file1 is renamed file2. where option is -i Protects you from overwriting an existing file by asking you > cp -r mp1 temp for a yes or no before it copies a file with an existing name. -

Unix Command Line; Editors
Unix command line; editors Karl Broman Biostatistics & Medical Informatics, UW–Madison kbroman.org github.com/kbroman @kwbroman Course web: kbroman.org/AdvData My goal in this lecture is to convince you that (a) command-line-based tools are the things to focus on, (b) you need to choose a powerful, universal text editor (you’ll use it a lot), (c) you want to be comfortable and skilled with each. For your work to be reproducible, it needs to be code-based; don’t touch that mouse! Windows vs. Mac OSX vs. Linux Remote vs. Not 2 The Windows operating system is not very programmer-friendly. Mac OSX isn’t either, but under the hood, it’s just unix. Don’t touch the mouse! Open a terminal window and start typing. I do most of my work directly on my desktop or laptop. You might prefer to work remotely on a server, instead. But I can’t stand having any lag in looking at graphics. If you use Windows... Consider Git Bash (or Cygwin) or turn on the Windows subsystem for linux 3 Cygwin is an effort to get Unix command-line tools in Windows. Git Bash combines git (for version control) and bash (the unix shell); it’s simpler to deal with than Cygwin. Linux is now accessible in Windows 10, but you have to enable it. If you use a Mac... Consider Homebrew and iTerm2 Also the XCode command line tools 4 Homebrew is a packaging system; iTerm2 is a Terminal replacement. The XCode command line tools are a must for most unixy things on a Mac. -

General Education and Liberal Studies Course List
GELS 2020–2021 General Education/Liberal Studies/Minnesota Transfer Curriculum 2020–2021 Course List This course list is current as of March 25, 2021. For the most current information view the Current GELS/MnTC list on the Class Schedule page at www.metrostate.edu. This is the official list of Metropolitan State University courses that meet the General Education and Liberal Studies (GELS) requirements for all undergraduate students admitted to the university. To meet the university’s General Education and Liberal Studies (GELS) requirements, students must complete each of the 10 goal areas of the Minnesota Transfer Curriculum (MnTC) and complete 48 unduplicated credits. Eight (8) of the 48 credits must be upper division (300-level or higher) to fulfill the university’s Liberal Studies requirement. Each course title is followed by a number in parenthesis (4). This number indicates the number of credits for that course. Course titles followed by more than one number, such as (2-4), indicate a variable-credit course. Superscript Number: • Superscript number (10) indicates that a course meets more than one goal area requirement. For example, NSCI 20410 listed under Goal 3 meets Goals 3 and 10. Although the credits count only once, the course satisfies the two goal area requirements. • Separated by a comma (3,LS) indicates that a course will meet both areas indicated. • Separated by a forward slash (7/8) indicates that a course will meet one or the other goal area but not both. Superscript LS (LS): • Indicates that a course will meet the Liberal Studies requirement. Asterisk (*): • Indicates that a course can be used to meet goal area requirements, but cannot be used as General Education or Liberal Studies Electives. -
