The following is a transcript of me connecting to the Zoo with ssh, creating directories and subdirectories to hold my work, and then editing, compiling, and running my program. The commands I entered are the ones after the prompt [jrg94@hawk ~]$.

jim@DESKTOP-INJKRF2 ~
$ ssh jrg94@node.zoo.cs.yale.edu                                    my cygwin terminal prompt

[jrg94@hawk ~]$ mkdir CPSC223          create a directory (folder) for 223 files (only need to do the mkdir commands once)
[jrg94@hawk ~]$ cd CPSC223             make that the working (current) directory
[jrg94@hawk CPSC223]$ mkdir P1         create a subdirectory in called P1 in the current directory (CPSC223)
[jrg94@hawk CPSC223]$ cd P1            make that the working directory
[jrg94@hawk P1]$ emacs hello.c         create the source code with emacs (no transcript of editing within emacs; Control-x Control-s to save and Control-x Control-c to quit)
[jrg94@hawk P1]$ gcc -o Hello hello.c  compile hello.c to produce executable called Hello
[jrg94@hawk P1]$ ./Hello               run the executable
Hello, world!                          the output of our program!
[jrg94@hawk P1]$ emacs log             create the log file
[jrg94@hawk P1]$ /c/cs223/bin/submit 1 hello.c log      submit source and log
