Hi,
I have a bash script that generates CSV (.txt) files at fairly regular time intervals. I'm currently time stamping each batch of measurements at the time I write the rows into a MySQL database. As the result, one set of data might get the time 12:01:32 and the next set of data gets the time 12:03:14. The average time between measurements is about 1-3 minutes.
This works fine, but I'm working on a frontend where I want to display measurements from various events in the same graphs, and the resolution should be 5 minutes.
So my script should ideally only kick off a new measurement every 5th minute and when it stores the times it should also be at even 5-minute intervals.
Some pseudo code showing the current behavior if it explains better:
To summarize the wanted behavior with an example:
The script starts a new measurement at a fixed 5-minute interval. For example, one interval should start at 12:00. It then generates the CSV file (it normally takes one to two minutes) and stores the values to the database with the start time for the interval (in this case 12:00). Then the script waits until 12:05 before it starts over with the same procedure again.

Hello All,
I'm generating timestamps (file creation timestamps) for all the files in a directory. I need to compare all the timestamps.

I'm looking for a way to have the "date" command output the date in a specific format.
I'm not familiar with the different ways to use the date command at all. i read up on it, but i dont get how to manipulate it.

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.
