Using the Unix-Like Utilities

1 Getting Started

The machines in the CS Department's Computer Labs all have a number of Unix-like utilities installed that can make your life much easier.

If you try to use one of these utilities and you get a message like:

    The name specified is not recognized as an
    internal or external command, operable program or batch file.

then you will need to modify the path to executables as follows:

    set PATH=%PATH%;"c:\Program Files\UnixTools\"

There are many Unix-like utilities available. Some of the most useful include:

`cut`	Cut columns from a text file
`grep`	Search files for text
`head`	Display the first few lines of a file
`hostname`	Display the name of the machine
`mv`	Move files between directories
`paste`	Paste columns into a text file
`pwd`	Display the current/working directory
`sleep`	Execute a command after a delay
`touch`	Change the date associated with a file
`uniq`	Remove duplicates records from a sorted file
`wc`	Count lines, words and characters
`which`	Find executables in the path
`whoami`	Display your login name
