 1 | Simple Loading Bar For Your Bash Script
 2 | =======================================
 3 | 
 4 | I needed a simple loading or progressing bar for some of my bash scripts. I like
 5 | pv. Its great. But an extra depency for my scripts. I dont like extra depencies
 6 | and this was just a one evening script. 
 7 | 
 8 | 
 9 | Output
10 | =====
11 | 
12 | The Output will look something like this:
13 | 
14 |     [            #####       ]
15 | 
16 | or
17 | 
18 |     (  ooooooooooooooo                   )
19 | 
20 | or 
21 | 
22 |     |                      =====  |
23 | 
24 | or whatever you specify as parameters ;) 
25 | 
26 | Usage
27 | =====
28 | 
29 | At first copy this in your script and change the first while condition to
30 | something useful to you. Maybe you would like to pack this into a function or
31 | something. But this is at least your part ;) 
32 | 
33 | Next you can specify your parameters (if you want to!)
34 | 
35 |     ./loading.sh maximal_size_of_bar speed_in_seconds first_delimiter fill_chars last_delimiter
36 | 
37 | For Example:
38 | 
39 |     ./loading.sh 50 0.02 [ "######" ]
40 | 
41 | Thats all. But keep an eye on special characters in Bash! Its possible that
42 | everything implodes. Use \\( for ( or "#" for # for example. 
43 | 
44 | At least you can start the script without any parameters:
45 | 
46 |     ./loading.sh
47 | 
48 | Hint
49 | ====
50 | 
51 | Remove the \r (Carrige return) from the script. Does make nice banners in your
52 | Terminal :) 
53 |
