Using the Pico Text Editor
For editing files on the servers, one option is the File Manager interface
in your account's CNC. The File Manager provides an easy-to-use, point-n-click
web interface that is recommended for most Site Owners who wish to create or
modify files directly on the FutureQuest® servers.
For those who would like to use a text editor in a telnet session, a simple
text editor that is installed on all servers is the Pico text editor. (Other
text editors which are installed as well are vi, emacs, ed and Midnight Commander.)
Note: The FutureQuest® Service Desk does not provide direct support for
the use of text editors. For assistance, please visit the Community
Forums.
Here are some basic tips to get you started with Pico.
Starting a Session with Pico
At the command line enter
[username@FQ-Server:~]$ pico filename.ext
If the file filename.ext already exists, then Pico
will open the existing file for editing. If the file filename.ext
does not exist, it will be created as a new file.
Using Pico for Editing
Note that the ^ symbol denotes the Control key. So ^G
means the key combination Ctrl-G, which brings up the Help
menu (for "Get Help"). As shown in the image below, Pico displays
the current file name and its status across the top of the screen, and across
the bottom are some listed commands.
Once you are inside the editor, you can simply begin typing. You can move around
in Pico with the arrow keys. Here are some additional navigational commands.
Note: The ^ symbol denotes the Control key.
Thus, ^A is the Ctrl-A key combination.
^A |
Move cursor to beginning of line. |
^B |
Move cursor back one character. |
^E |
Move cursor to end of line. |
^F |
Move cursor forward one character. |
^N |
Move cursor to next line. |
^P |
Move cursor to previous line. |
^V |
Move cursor forward a page of text. |
^Y |
Move cursor backward a page of text. |
Additional editing commands:
^R |
Insert the contents of a textfile at the current cursor position. |
^^ |
Mark the current cursor position as the start of a text selection. |
^K |
Cut (delete) the current line or marked text. |
^U |
Uncut (paste) the text that was last deleted, at the current cursor
position. By cutting in one location, moving cursor to a new location, and
then uncutting, you can move text easily. |
^L |
Redraw the screen. |
^G |
Get Help. (Display the Pico Help File.) |
A complete list of commands can be found by using the ^G
(Ctrl-G) "Get Help" command.
Saving and Exiting
To save without exiting, use the ^O command. Pico may suggest
a file name to save to, or you may have to enter one. Once you have the desired
file name showing, hit <Enter> to finish saving.
To exit, use ^X. If there have been any changes made to
the file, Pico will ask whether you would like to save. Type Y
to save, or N to exit without saving. If you tell Pico to
save, it will prompt for a file name. You may edit any suggested file name.
Once you have the desired file name showing, hit <Enter>
to finish saving and exit.
