+# progress_bar.sh
+Progress bar for the shell
+
+Display a progress bar for `$1` seconds.
+
+![progress bar](resources/progressbar.gif)
+
+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
+```
