Plus, bash creates a subprocess (different from ksh) on the right side of a pipe, meaning any changes to variables in the statement on the right are not returned to the parent. This changed with bash 4.2, so it may be what you are seeing with v6 versus v7. Check the listpipe bash option help for more information. But I think ChublerXL has a solid answer.
PS:
I do not see the the opening ( in your example. Generates an error for me.

Hello all,
I am planning to deploy a configuration / auditing software package for about 100 new nodes that we are planning to install. I am hearing many good things in regards to cfengine and puppet. Can someone shed some light in regards to these solutions?
Thanks,

Have a sudo statement inside of a here document. It prompts me for a password, but doesnt wait for me to enter my password. Is there a way I can use the command without sudo or anyway that I can enter the password correctly?

I am being pushed from AIX onto RHEL 6 and after our first 'chuck it on' install, I have a problem. Where is the old (okay insecure) telnet & ftp server? I know that they are probably regarded as archaic now, but the source servers do not have the SSH tools, so I've got to somehow transfer the... (4 Replies)

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.
