Copy Queue

A command line "cp" and "mv" that use a queue.

Warning! I don't take any responsibility for any loss of data.

Use these scripts at your own risk.

Target operating systems: Unix/Linux. Tested with Python 2.7.

Usage

-----

    cpq file1 /trash/movies/

    cpq file2 /trash/movies

    mvq file3 /trash/movies/

All the three files are put in a queue and only one is

processed at a given time.

Motivation

----------

If you launch the previous 3 commands with "cp" and "mv" in

the background, then all three will run concurrently, thus

your machine will slow down because of the I/O operations.

If you launch them in the foreground, then you have to wait

until one finishes and then you can start the next one.

You can always use a graphical file manager that supports a

copy queue but I prefer to work in bash in combination with

the good old Midnight Commander. And in MC I didn't find this

feature.

Installation

------------

In the file `config.py` you can customize all the directory

and file paths. For an easier understanding, I will explain

the usage of the scripts with the default values.

First, clone this project to the following directory:

`$HOME/python/Copy-Queue`.

Then create the directory `$HOME/bin` and add these two

symbolic links:

    cd $HOME/bin

    ln -s $HOME/python/Copy-Queue/cpq_mvq.py cpq

    ln -s $HOME/python/Copy-Queue/cpq_mvq.py mvq

Make sure that `$HOME/bin` is in your `PATH`.

Finally, create the directory `$HOME/bin/copy_queue`.

Now you are ready to use "cpq" and "mvq".

Tips

----

If there is a directory where you copy/move very often, then

you can add this directory to your `.bashrc` file. For instance,

I copy a lot of videos to my Android phone, thus I created the

following shortcut in my `.bashrc`:

    # Android's Video directory

    A='/media/jabba/2B9A-EB28/Video'

    export A

Then I can copy videos to my Android this way:

    cpq movie.avi $A

Another tip: the scripts create a log file. If you want to see

the copy/move progress, create the following alias:

    alias Q='tail -f $HOME/bin/copy_queue/daemon.log'

To check if the tasks are finished, just launch `Q`:

    $ Q

Update (20170415)

-----------------

I found today a simple Unix batch system called

task spooler ([AUR](https://aur.archlinux.org/packages/task-spooler/),

[PPA](https://launchpad.net/ubuntu/+source/task-spooler)).

Task spooler is more general than my approach since you can send

any Unix command in its queue. Task spooler is a better solution

than mine. It also provides more options, so I suggest using task spooler.

Here is a short video about its usage: .
