All commands must be typed in lower-case letters unless noted otherwise. Displaying a Directory ls-- Lists the names of files in a particular UNIX directory. If you type the ls command with no parameters or qualifiers, the command displays the files listed in your current working directory. When you give the ls command, you can add one or more modifiers to get additional information.

Example: ls Result: Lists the names of files in your default directory, in alphabetical order. Example: ls -l Result: Gives a 'long listing' of the files in your directory.

In addition to the file name, the long listing shows protection information, file owner, number of characters in file, and the date and time of the last change to the file. Example: ls -a Result: Causes all your files to be listed, including those files that begin with a period (i.e., hidden files). For more information, type man ls at the UNIX system prompt. Displaying and Concatenating (Combining) Files more-- Enables examination of a continuous text one screenful at a time on a terminal.

It normally pauses after each screenful, printing -- More -- at the bottom of the screen. Press RETURN to display one more line. Press the SPACE BAR to display another screenful. Press the letter Q to stop displaying the file. Example: more newfile Result: Displays the contents of 'newfile' one screen ('page') at a time.

For more information about this command, type man more at the UNIX system prompt. Cat-- Displays the contents of a file on your terminal. Example: cat newfile Result: Displays the contents of the file 'newfile' on your terminal. Invert Print Color Pdf. Example: cat newfile oldfile Result: Displays the contents of two files -- 'newfile' and 'oldfile' -- on your terminal as one continuous display.

The interrupted command displays lines beginning at the point at which processing was interrupted. The cat command is also used to concatenate (combine) files and put them into another file. If you concatenate files to another one that already exists, the existing contents are permanently lost. Example: cat fileone filetwo filethree >newfile Result: Links together three files -- fileone, filetwo and filethree -- into a new file called 'newfile'. The original files remain intact.

For more information about the cat command, type man cat at the UNIX system prompt. Copying Files cp-- Makes copies of your files. You can use it to make copies of files in your default directory, to copy files from one directory to another directory, or to copy files from other devices. Example: cp fileone filetwo Result: Copies the contents of fileone to a file named filetwo.

Two separate files now exist. Example: cp /usr/neighbor/testfile. Result: Copies the file testfile from the directory /user/neighbor to your UNIX account. ) at the end of the command line indicates that the file is to be copied to your current working directory and the name will remain the same. To copy a file from another user's directory on UNIX, you must know the person's username.
