Common File Commands cp {f 1} {f 2} mv {f 1} {f 2} rm {f 1} g++ {f 1} Copy file {f 1} into {f 2} Move file {f 1} to {f 2} Delete file {f 1} Compile C++ file {f 1} using g++ compiler. CSE 1222: Unix Intro The Ohio State University 5

Example > cd > pwd /home/3/yourusername > mkdir lab 2 > cp lab 1/first. cpp lab 2/second. cpp > cd lab 2 > ls second. cpp > CSE 1222: Unix Intro The Ohio State University 6

Example > cd lab 2 > ls second. cpp > g++ second. cpp > ls a. out second. cpp > rm a. out > ls second. cpp > CSE 1222: Unix Intro The Ohio State University 7

More Unix Commands control-C Interrupt a program or command control-Z Suspend a program bg Place suspended program in background. fg Place suspended program in foreground. jobs List background programs. CSE 1222: Unix Intro The Ohio State University 9

Example of Background Jobs > emacs first. cpp & [1] 29943 > jobs [1] + Running emacs first. cpp > emacs second. cpp & [2] 29945 > jobs [1] + Running emacs first. cpp [2] – Running emacs second. cpp CSE 1222: Unix Intro The Ohio State University 10

Example of Background Jobs > jobs [1] + Running [2] – Running > fg emacs first. cpp emacs second. cpp Suspended > bg [1] emacs first. cpp & CSE 1222: Unix Intro The Ohio State University 11

emacs Example > emacs first. cpp g++ first. cpp CSE 1222: Unix Intro The Ohio State University 12

emacs Example > emacs first. cpp g++ first. cpp ls CSE 1222: Unix Intro The Ohio State University 13

emacs Example > emacs first. cpp g++ first. cpp ls Why won’t my computer respond? What’s wrong? CSE 1222: Unix Intro The Ohio State University 14

emacs Example > emacs first. cpp g++ first. cpp ls Why won’t my computer respond? What’s wrong? Please help me Mr. Instructor. CSE 1222: Unix Intro The Ohio State University 15

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 > CSE 1222: Unix Intro The Ohio State University 16
