I'd like to correct: last one is not the same!
I've tryed it:
I do not even understand why it is happened this way?!
First time by 'eval' the $nn should be substituted for 'aa' and '"' should be remuved (as I understand!). So result should be
and that by next processing should be as expected! But it prints only aa ?!
-------------------------
Ok, I've get it! It should be little bit different:
Now it is going to result the same!
So: the 'eval' do NOT evaluates value in double quotations or after backslash, but removes that quotations and backslashes!
I don't understand this, can anyone explain the evaluation logic used here, and I would really appreciate a general explanation for it.

Can someone help me out here. I can't get this piece of code to work. i.e. $ALL_EVENTS does not get interpreted in the if brackets. The first part is the code, the second part is the execution of the code. Note: $ALL_EVENTS does equal 2, but there is no value once passed to the if statement. ... (4 Replies)

Hi,

So here is an example code:

LDBASH(1) libbash Manual LDBASH(1)NAME
ldbash -- Dynamic loader for libbash(7) libraries.
SYNOPSIS
ldbash [-h | --help]
ldbash [-l | --list]
ldbash [-L | --load lib,[lib] ...]
ldbash [-U | --unload lib,[lib] ...]
ldbash [-e | --externlist lib,[lib] ...]
ldbash [--externlist-all]
ldbash [--i | --internlista lib,[lib] ...]
ldbash [--internlist-all]
DESCRIPTION
ldbash is used to manipulate libbash(7) libraries. Its main function is to load specific library. It can also print list of available
libraries, list functions each library exports, unload functions, etc.
In case of --load and --unload ,the output is intended to be passed to bash eval command.
Options-h | --help Print options summary
-l | --list Display list of available libraries. The libraries names listed, may be passed as parameters to other invocations of ldbash.
I.e. first you run ldbash --list to see what is available and then you may load it.
-L | --load lib,[lib] ...
Load given libraries - i.e. print string that should be passed to eval command. Usually the string contains various source
commands.
Libraries that given libraries depend on are also loaded.
Libraries only loaded if their dependencies are satisfied. Dependencies are resolved using ldbash.cache file, which is created
by ldbashconfig(8).
-U | --unload lib,[lib] ...
Unload given libraries, but not their dependencies.
The output should be passed to eval command (in the same manner as with --load ).
-e | --externlist lib,[lib] ...
List all symbols that are exported by given libraries. Symbols are usually functions that given libraries implement.
--externlist-all
List all exported symbols of all available libraries. Symbols are usually functions that library implement.
-i | --internlist lib,[lib] ...
List all internal symbols (i.e. global variables/functions) of given libraries. This is intended mostly for developers that
want to develop library of their own, and want to be sure that they don't override any already defined symbol.
--internlist-all
List all internal symbols of all available libraries. This is intended mostly for developers that want to develop library of
their own, and want to be sure that they don't override any already defined symbol.
FILES
/etc/ldbash.cache
Cache file that contains information about libraries dependencies and list of exported symbols. See ldbashconfig((8)) for further
details.
BUGS
The script can't load libraries if their file name starts with '-'. (If someone uses file names that start with a '-' he/she deserves it!)
