Using Linux - Large Text Files
This page is a part of the Linux and CS Systems - Getting Started. This page assumes you have your computer setup to connect to the CS server, or have the appropriate software installed on your computer to run commands. Go back to the Linux and CS Systems Getting Started main page if you don't have our system setup yet.
Large Text File
On this page we walk you through looking at a text file that contains the complete works of Shakespeare (courtesy of Project Gutenberg). The file was downloaded from . How many lines and words are there in this file? The file is a bit large to open with Word (you can try, it takes a while for it to actually load). So instead of opening the file in Word, we can use some of our Linux commands to get some information about the file. Check back at the Linux and CS Systems Getting Started page for more commands that might be useful.
The sample session here shows how you can copy the file into your account on the CS server and check how many lines and words are in the file. If you would like to follow along and run these commands, first login to the system and open up the terminal.
First, we create a directory in our home directory for keeping the shakespeare file.
cs299@cs:~> cd ~ cs299@cs:~> mkdir shakespeare cs299@cs:~> cd shakespeare
Next we copy the text file from where it is stored on the CS server and use the wc command to see how many lines, words, and characters (bytes) are in the file.
cs299@cs:~/shakespeare> cp /u1/junk/shakespeare.txt . cs299@cs:~/shakespeare> ls shakespeare.txt cs299@cs:~/shakespeare> wc shakespeare.txt 124787 904061 5589890 shakespeare.txt
You can also use the nano text editor (or whatever text editor you like) to look through the text file.
cs299@cs:~/shakespeare> nano shakespeare.txt
You can use the head and tail commands to look at the start and end of a text file, and grep to look for particular lines in the file.
