| Method: | Do the following:
- Upon entering the lab log on using your PODS userid and password. You will be logged
into a Debian linux environment. To get to a command line environment locate a terminal icon or menu
choice and select it, this should open up what is
known as a terminal window which gives you a linux command line environment.
On the surface, this looks like the Windows command environment (remember, Unix came before DOS and is what
DOS was
modeled after). The Linux help system is accessible through the system "man" pages.
This is standard on all Unix/Linux distributions. "man"is short for manual (but the command is "man").
To look up the help for a particular command type and the command "man" (without quotes) followed by
the command you are interested in followed by the ENTER key.
For example to look at the help for the "pwd" command typeman pwd
This will open up the man program and display the help for the command you asked for.
In the man page environment, togo forward to look at additional information depress the enter key.
To exit the man page program type the letter "q".
Explore the man pages for the following commands;
using your own words write definitions for what each does (submit this text file as part of the
Lab, name the file definitions.txt).
- man
- pwd
- mkdir
- rmdir
- cd
- ls
- find
- locate
- g++
- While in the lab write a "HelloWorld" program (one will be gone over in class).
Use the nano editor (or gedit) program to create the source file in your home directory
(when you use the lab machines your "home" directory is your
bingsuns account). Hint = the source file must be type .cpp or the compiler won't recognize it. To
compile the source file:
To compile your helloworld.c file type:javac helloworld.java
fix any errors that the compiler may detect by editing the source file.
When everything is OK (i.e. no errors) run your program by typing:java -classpath . helloworld
- FTP all of the files to the lab1 directory of your FTP account on the bigblackbox.cs.binghamton.edu server.
This should include:
- definitions.txt
- helloworld.java
