Hi,
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 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_metainit
DH_METAINIT(1) User Contributed Perl Documentation DH_METAINIT(1)NAME
dh_metainit - install metainit files into package build directories
SYNOPSIS
dh_metainit [debhelper options] [--name=name] [-n] [-o]
DESCRIPTION
dh_metainit is a debhelper program that is responsible for installing metainit files (for further creation of initscripts via the update-
metainit facility) into package build directories.
It also automatically generates the postinst and postrm and prerm commands needed to create the appropriate initscripts for the init system
employed on the user machine.
Important: If generated postinst script finds /etc/init.d/ or /etc/default files with the same name as the shipped metainit files, and
these are conffiles from non-installed packages (probably earlier version of this package) they are removed (or renamed if the user has
modified them). This works only if the name of the new metainit is the same as the name of the old init.d and default file, otherwise you
will have to remove these files yourself. See http://wiki.debian.org/DpkgConffileHandling for that.
If a file named debian/package.metainit exists, then it is installed into etc/metainit/package in the package build directory, with "pack-
age" replaced by the package name.
OPTIONS -n, --noscripts
Do not modify postinst/postrm/prerm scripts.
-o, --onlyscripts
Only modify postinst/postrm/prerm scripts, do not actually install any metainit files. May be useful if the init script is shipped
and/or installed by upstream in a way that doesn't make it easy to let dh_metainit find it.
--name=name
Install the metainit script using the filename name instead of the default filename, which is the package name. When this parameter is
used, dh_metainit looks for and installs files named debian/package.name.metainit, instead of the usual debian/package.init.
--error-handler=function
Call the named shell function if running the init script fails. The function should be provided in the prerm and postinst scripts,
before the #DEBHELPER# token.
NOTES
Note that this command is not idempotent. "dh_clean -k" should be called between invocations of this command. Otherwise, it may cause mul-
tiple instances of the same text to be added to maintainer scripts.
SEE ALSO debhelper(7)
This program is a part of debhelper.
