Utility is compatible with Linux, Mac OS X and FreeBSD. Theoretically, it should work fine on any Unix-based platform integrated with freedesktop.org.
You can use gem to install bcat:
gem install bcat
Let's test it by opening year of 2014 calendar:
python -c "import calendar ; print calendar.HTMLCalendar().formatyear(2014)" | bcat
A new tab should open in your default browser with the calendar if everything is working properly.
Preview log files
tail -n 1000 -f /var/log/messages | bcat
Now your browser works pretty much like tail.
Here is how the remote log file can be opened:
ssh mywebsite.com 'sudo tail -f /var/log/nginx/access.log' | bcat
Use it as a pager
bcat can be used as a pager for various programs.
export MANPAGER='sh -c "col -b | bcat"'
Now, when you run «man grep» or «git log», the browser's window will be focused and the output will be printed in a new tab. By the way, if you have Git colors enabled, then the colors will also be shown in a browser.
Viewing the clipboard
xclip -o -selection c | bcat
For Mac OS X:
pbpaste | bcat
View the Markdown file with formatting:
markdown README.md | bcat
Of course, you can mix different commands. For example, here is how to view the clipboard with Markdown formatting enabled (for Linux):
xclip -o -selection c | markdown | bcat
For Mac OS X:
pbpaste | markdown | bcat
These are just simple examples. I'm sure you can find much more use cases for this handy utility.
