Linux Text Editors

The Pico Editor

To start Pico Editor, enter a command like this:

pico bibin.joke

In response, you should see the file bibin.joke displayed on your screen in Pico, ready for editing, as shown here:

The Pico Menu
When you start Pico you'll see this menu of commands:

^G Help ^O WriteOut ^R Read File ^Y Prev Pg ^K Cut Text ^C Cur Pos
^X Exit ^J Justify ^W Where is ^V Next Pg ^U UnCut Text ^T To Spell
Here's a list of what they mean. Note that the circumflex (^) stands for ctrl.

Pico Commands

Trying Out Some Pico Commands
Now let's try out some Pico commands.

Saving and Exiting
Saving your file is easy with Pico--just press ctrl-O to write your file to disk and remain in the editor, or press ctrl-X and respond y to the Save Modified Buffer? prompt to save and exit. If you want to exit from Pico without saving your file, press ctrl-X and respond n to the Save Modified Buffer? prompt.

Inserting Another File
To insert another file into the one you're currently editing, position the cursor where you want to insert the file, press ctrl-R, and enter the name of the file you wish to insert at the prompt that appears on your screen:

Insert file from home directory: ______________
^G Get Help ^T To Files
^C Cancel

If you can't remember the name of the file to insert, press ctrl-T to display a list of all your files. If you ultimately decide not to insert it, press ctrl-C to cancel.

Cutting and Pasting with Pico
If all you want to do is cut and paste a line of text, you can use ctrl-K to delete the current line and ctrl-U to paste it somewhere else. Pico also lets you cut and paste blocks of text. Put your cursor on the word light on the first line of the bibin.joke file and press ctrl-^ ( the circumflex is the shifted 6 key). Nothing happens right away, but as you move the cursor, it highlights a block of text. Move the cursor to the end of the word giraffe on the next line--your file should look like this:

Once you've marked a block of text, ctrl-K acts a bit differently from before. Instead of deleting the entire line where the cursor is located, it deletes the highlighted block. You can then use ctrl-U to paste the deleted block elsewhere.
Tip: You don't have to paste the deleted text right away, or ever. ctrl-K can be used simply as a handy way of deleting unwanted text. (Deleted text goes to an invisible clipboard, and it disappears once you delete more text.)

Pico Bells and Whistles
Pico has a few nifty features you might not expect to find in a simple text editor. For example, ctrl-J will justify the sentences in the current paragraph. Type a bunch of short sentences on separate lines and try it. If you don't like the results, ctrl-U will undo the operation. Pico also has a built-in spelling checker you can call up with ctrl-T from within a file. If Pico doesn't find any dubious words in the current document, nothing much happens except that the message "Done checking spelling" appears at the bottom of the screen. And if you'd like to know exactly where you are within a file (on which line and at which character), or if you'd like a quick character or line count, press ctrl-C and look in the message area at the bottom of the screen for something like this:

line 2 of 4 (50%), character 65 of 173 (37%)

Parting Words about Pico
Pico is my personal favorite in text editors because it's easy to use and starts quickly. Pico is under constant development at the University of Washington. For more information, you can visit the Pine Information Center on the Web at http://www.washington.edu/pine. You can even download the latest version of Pico for Linux there.
