Please explain in English what the following code is intended to do:
Given that the variable out is never used after being defined by the above statement, are these two lines of code needed?
What happens if you insert the missing done in your script before or after the code discussed above (which should resolve the syntax error in your script)?

I have searched the internet (including these forums) and perhaps I'm not using the right wording.
What I'm looking for is a function (preferably C) that analyzes the similitude of two numerical or near-numerical values, and returns either a true/false (match/nomatch) or a return code that... (4 Replies)
Hi,
I am trying to write a script which parses a log file and will eventually put the values in an array so that I can perform some math on it. In this file I am only interested in the last 200 lines so here is the command I use to display the contents in a manageable manner.

Dear All,
assume i have a file with content:
<Start>6000</Start>

the output is:
6000
7000
7100
7200

how should we use any awk, sed, perl can do this task, means to extract the uniq prefixes from the start and stop prefix.
Thanks

I am trying to create a cronjob that will run on startup that will look at a list.txt file to see if there is a later version of a database using database.txt as the source. The matching lines are written to output.

In the file1 below if $9 and $12 are . (dot) then the value in $8 of file1 is used as a key (exact match) to lookup in each $2 of file2, when a match is found then the value of $4

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.
