If you want to shorten a file to zero length, which might be written to by a background process, do:
This reduces the file immediately while preserving its inode, so that the process that holds it open can still write to it.
Note that the "cat /dev/null" part is useless as there is nothing to cat from /dev/null in the first place. You can actually shorten a file with any command that output nothing, e.g. :
or
and with most shells like sh, dash, bash, ksh, zsh and the likes (actually any shell but the csh family ones), you can even skip the command and only use a redirection for the expected effect :
Hi
I'm trying to install gcc and the installation program tells me that I'm out of disk space! I have just installed the os (using the default settings for partitions and sizes) and have only installed apache on the machine. Can it really be out of disk space already?

Hello,
Can someone please tell me which command to use to determine the available disk space on a given disk device?
I have to write a shell script that compresses files and stores them in a specific location but I am not sure how "conservative" I should be?
Thanks in advance!

fixup_datafile
fixup_datafile(3alleg4) Allegro manual fixup_datafile(3alleg4)NAME
fixup_datafile - Fixes truecolor images in compiled datafiles. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void fixup_datafile(DATAFILE *data);
DESCRIPTION
If you are using compiled datafiles (produced by the dat2s and dat2c utilities) on a platform that doesn't support constructors (currently
any non GCC-based platform), or if the datafiles contain truecolor images, you must call this function once after your set the video mode
that you will be using. This will ensure the datafiles are properly initialised in the first case and convert the color values into the
appropriate format in the second case. It handles flipping between RGB and BGR formats, and converting between different color depths when-
ever that can be done without changing the size of the image (ie. changing 15<->16-bit hicolor for both bitmaps and RLE sprites, and
24<->32-bit truecolor for RLE sprites).
Note that you can only call this once and expect it to work correctly, because after the call the DATAFILE you fixed up is permanently con-
verted to whatever is the current component ordering for your screen mode. If you call fixup_datafile again, the function assumes you have
a freshly loaded datafile. It cannot "undo" the previous conversion.
If your program supports changing resolution and/or color depth during runtime, you have two choices: either call fixup_datafile() just
once and hope that the component ordering and bit depth doesn't change when the screen mode changes (unlikely). Or, you can reload your
datafiles when the screen mode changes.
