I have used m4 in the past to generate source code where aesthetics and space were of no consequence [ provided it worked ]. Now I am using it to generate script and program templates [ in an effort to improve the readability and general soundness of my scripts/programs ].
So here is an excerpt from my m4 file for producing a generic bash script:
It outputs what you'd expect but tacks on 16 blank lines at the beginning of the file. I can use sed to remove these but I am thinking there is an m4 basic I am missing. I've looked through the docs and various tutorials. Maybe I have a buggy m4?
Thanks!

Hi there,
When I run top on my machine it says I have 497M swap space in use, and 380M swap space free,
but I have only allocated 512M swap space to the machine!!!!
Does anyone know how swap used is calculated in the top command?
Thanks... (1 Reply)
Hi everybody,
I want to know if there is any posibility to find out - on an AIX system - which are the the users who consume most space or at least a posibility to obtain a list with all the users and how much space are they consuming ?
Trying to use du command was useless. Any idea?... (5 Replies)
Hi all, I am needing a bash shell script to generate a list of the top 5 users using the most disk space. I am thinking that the du command would be used somehow but I am at a loss. Can anyone help? Thanks! (3 Replies)
for diskname in $(lspv |awk '{print $1}')
do
lquerypv -h /dev/|awk '/'$diskname'/ { print ; exit }'
done
No output is returning from the loop.
I think awk put an extra space to the command - lquerypv -h /dev/
so that the command is executed as i.e. lquerypv -h /dev/ hdisk230 with a space... (7 Replies)
Hi,
Since today, with csh or tcsh, if I do 'ls files* > list',
every lines end with an extra space!
What happenned?
What can I do to go back when there was no extra space?
If I change to bash, there's no extra space.
Thanks,
Patrick

LIBBASH(7) libbash Manual LIBBASH(7)NAME
libbash -- A bash shared libraries package.
DESCRIPTION
libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
want to load and use in scripts of your own.
It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.
Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1). A bash shared library that can be loaded
using
ldbash(1) must answer 4 requirments:
1. It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).
2. It must contain a line that begins with '#EXPORT='. That line will contain (after the '=') a list of functions that the library
exports. I.e. all the function that will be usable after loading that library will be listed in that line.
3. It must contain a line that begins with '#REQUIRE='. That line will contain (after the '=') a list of bash libraries that are
required for our library. I.e. every bash library that is in use in our bash library must be listed there.
4. The library must be listed (For more information, see ldbashconfig(8)).
Basic guidelines for writing library of your own:
1. Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.
2. Try to declare all variables intended for internal use as local.
3. Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
__<library_name>_
For example, internal function myfoosort of hashstash library should be named as
__hashstash_myfoosort
This helps to avoid conflicts in global name space when using libraries that come from different vendors.
4. See html manual for full version of this guide.
