# progress_bar.sh
|
|
Progress bar for the shell
|
|
|
|
Display a progress bar for `$1` seconds.
|
|
|
|
|
|
|
|
It uses [partial Unicode blocks](https://en.wikipedia.org/wiki/Block_Elements#Character_table) to achieve subcharacter precision.
|
|
|
|
Example:
|
|
|
|
```
|
|
source progress_bar.sh
|
|
progress_bar 60
|
|
│█████████████████████████████████████████████████████████▌ │ 62%
|
|
```
|
|
|
|
You can time a long task and use it to have an idea of how much longer to wait
|
|
|
|
```
|
|
time ./compile.sh # gives 300 seconds
|
|
./compile.sh &>/dev/null & progress_bar 300
|
|
│███████████████████████████████ │ 31%
|
|
```
|
|
|
|
It requires a terminal session with unicode locales, for instance
|
|
|
|
```
|
|
export LC_ALL=en_US.UTF-8
|
|
export LANG=en_US.UTF-8
|
|
export LANGUAGE=en_US.UTF-8
|
|
```
|
