I have a log file which is constantly being written to by some process. I need to clear that log file on a daily basis.
The problem is that when I issue this command:
echo "" > logfile.log
the file gets filled with nulls thus increasing the size of the file.

Hi
I tried to empty an existing file (bring the size of the file down to 0). When I used “> myFile” or “cat </dev/null >myFile”, when I do a “ls –la”, the file size shows as 0.
I then wrote 540 lines to the file, and then opened it using vi, I see something like this:
"myFile" 540 lines,... (3 Replies)

dh_compress
DH_COMPRESS(1) Debhelper DH_COMPRESS(1)NAME
dh_compress - compress files and fix symlinks in package build directories
SYNOPSIS
dh_compress [debhelperoptions] [-Xitem] [-A] [file...]
DESCRIPTION
dh_compress is a debhelper program that is responsible for compressing the files in package build directories, and makes sure that any
symlinks that pointed to the files before they were compressed are updated to point to the new files.
By default, dh_compress compresses files that Debian policy mandates should be compressed, namely all files in usr/share/info,
usr/share/man, files in usr/share/doc that are larger than 4k in size, (except the copyright file, .html and other web files, image files,
and files that appear to be already compressed based on their extensions), and all changelog files. Plus PCF fonts underneath
usr/share/fonts/X11/
FILES
debian/package.compress
These files are deprecated.
If this file exists, the default files are not compressed. Instead, the file is ran as a shell script, and all filenames that the shell
script outputs will be compressed. The shell script will be run from inside the package build directory. Note though that using -X is a
much better idea in general; you should only use a debian/package.compress file if you really need to.
OPTIONS -Xitem, --exclude=item
Exclude files that contain item anywhere in their filename from being compressed. For example, -X.tiff will exclude TIFF files from
compression. You may use this option multiple times to build up a list of things to exclude.
-A, --all
Compress all files specified by command line parameters in ALL packages acted on.
file ...
Add these files to the list of files to compress.
CONFORMS TO
Debian policy, version 3.0
SEE ALSO debhelper(7)
This program is a part of debhelper.
