Linux

Reclaiming free space after deleting log files

If a filesystem is full (for example /var) and you delete some log files in order to make some room on the filesystem, you observe that the space does not appear to be there when running the df command. The solution to this is to restart the application which is using the log files deleted. e.g: if you delete an apache log file then you should restart the httpd service.
% service httpd restart will do the trick nsc

Typing Greek in Linux Fedora Core 4changing the keyboard maping to greek 319

First of all download this file from the UCY CS Dept. ftp server [1] ... This file contains some files...We are interested on the two of them: el319 and en319! You have to put them in the following folder(be sure you are logged in as a superuser). So lets start : Extract the contents of the package in a folder

    tar -xvf gr319kb.tar.bz2 

and copy those two files in the /etc/X11/xkb/symbols/pc/ folder... you can run the following commands from that folder:

    cp el319 /etc/X11/xkb/symbols/pc/el319

    cp el319 /etc/X11/xkb/symbols/pc/en319

(After that if you want to load those key-maps you can type :setkeymap el319 (or en 319) in order to have the mapping you need...(NOT RECOMENDED))

If you want to have the mapping loaded in the system by default and switch between mappings with alt-shift you have to make some changes to the file /etc/X11/xorg.conf . So , open that file with an editor and find the line that describes the keyboard mapping configuration...That should be under the Section "InputDevice". After all those comments we have to change(or/and add) some lines and make them look like this:

...

Section "InputDevice"

...

Identifier "Keyboard0"

Driver "kbd"

Option "XkbModel" "pc104"

Option "XkbLayout" "en319,el319"

Option "XkbOptions" "grp:alt_shift_toggle,grp_led:scroll"

EndSection

...

change everything that needs to be changed in those lines and save the file... Restart the X server(or the computer) and the new configuration will be loaded. From that time you can change the keyboard layout by pressing alt-shift(just like windows!).

NOTE:After the restart you will be asked to use: gnome or X configuration...Be sure you choose the X configuration!

General

Handling multiple messages in pine.

In order to handle multiple messages at once using pine, you first have to enable the aggregate commands: Setup<S> -> Config<C> and check the enable-aggregate-command-set option as shown in Figure 1

Figure 1

.

This option adds: a Select command (;) to select messages by various criteria (From, Subject, Date, etc); a Select Cur (:) to select the current message; an Apply command (A) to apply commands such as Save(S), to save all Selected messages; and Zoom (Z) to restrict the messages shown in the Folder Index to just the selected ones; and Del (D) to delete all Selected messages.

Open the folder you want to handle and click the semicolon (;) Select the messages you want to handle by any criteria that you like, {e.g.: if you want to select a range of message type (N) and then the range (1-1000) and hit enter} then hit (A) and select the command you would like to apply to them{e.g.: (D) To delete the selected messages (X) after (D) will also expunge the messages}.
