2. Common Directory Commands  lsList directory contents  cd {dir}Change working directory to {dir}  pwdPrint working directory  mkdirMake a new directory  rmdir {dir}Delete directory {dir} CSE1222: Unix IntroThe Ohio State University2

3. Example > cd lab1 > pwd /home/3/yourusername/lab1 > ls a.out first.cppfirst.cpp~ > cd > pwd /home/3/yourusername CSE1222: Unix IntroThe Ohio State University3

4. Example > cd > pwd /home/3/yourusername > mkdir lab2 > cd lab2 > pwd /home/3/yourusername/lab2 > ls > CSE1222: Unix IntroThe Ohio State University4

5. Common File Commands  cp {f1} {f2}Copy file {f1} into {f2}  mv {f1} {f2}Move file {f1} to {f2}  rm {f1}Delete file {f1}  g++ {f1} Compile C++ file {f1} using g++ compiler. CSE1222: Unix IntroThe Ohio State University5

6. Example > cd > pwd /home/3/yourusername > mkdir lab2 > cp lab1/first.cpp lab2/second.cpp > cd lab2 > ls second.cpp > CSE1222: Unix IntroThe Ohio State University6

7. Example > cd lab2 > ls second.cpp > g++ second.cpp > ls a.outsecond.cpp > rm a.out > ls second.cpp > CSE1222: Unix IntroThe Ohio State University7

8. More File Commands  more {f1}View file {f1}  less {f1}View file {f1}  emacs {f1}Edit file {f1} using emacs  lp –d lj_cl_112_a {f1} Print file {f1} on printer lj_cl_112_a. CSE1222: Unix IntroThe Ohio State University8

9. More Unix Commands  control-CInterrupt a program or command  control-ZSuspend a program  bgPlace suspended program in background.  fgPlace suspended program in foreground.  jobsList background programs. CSE1222: Unix IntroThe Ohio State University9

10. Example of Background Jobs > emacs first.cpp & [1] 29943 > jobs [1] + Running emacs first.cpp > emacs second.cpp & [2] 29945 > jobs [1] + Runningemacs first.cpp [2] – Runningemacs second.cpp CSE1222: Unix IntroThe Ohio State University10

11. Example of Background Jobs > jobs [1] + Runningemacs first.cpp [2] – Runningemacs second.cpp > fg emacs first.cpp Suspended > bg [1] emacs first.cpp & CSE1222: Unix IntroThe Ohio State University11

12. emacs Example > emacs first.cpp g++ first.cpp CSE1222: Unix IntroThe Ohio State University12

13. emacs Example > emacs first.cpp g++ first.cpp ls CSE1222: Unix IntroThe Ohio State University13

14. emacs Example > emacs first.cpp g++ first.cpp ls Why won’t my computer respond? What’s wrong? CSE1222: Unix IntroThe Ohio State University14

15. emacs Example > emacs first.cpp g++ first.cpp ls Why won’t my computer respond? What’s wrong? Please help me Mr. Instructor. CSE1222: Unix IntroThe Ohio State University15

16. emacs Example Either:  Use the ‘&’ to place the emacs program in background, i.e.: > emacs first.cpp & [1] 29943 > Or:  Close the emacs window before issuing any other commands. > emacs first.cpp > CSE1222: Unix IntroThe Ohio State University16
