Fix Bash Error in Docker
I really enjoy working with Docker because it gives me more insight into creating and maintaining your own environments, mostly from scratch. I instantly gained a greater appreciation for Ops engineers, package creators, and other engineers who work on low level software. I think what I'm trying to say is that I've made a whole bunch of mistakes and completed an insane amount of Google searches for help.
One of the more basic errors I've recently encountered was trying to run a bash script within the container, only to get the following error: env: can't execute 'bash': No such file or directory. I was under the impression that bash was always a given in Linux machines, but apparently not in alpine images. The fix was adding the following to my Dockerfile file:
RUN apk update && apk add bash
Or if you're in the machine, just run:
apk update && apk add bash
That command installs bash and your bash scripts should then work!

![CSS Ellipsis Beginning of String]()
I was incredibly happy when CSS text-overflow: ellipsis (married with fixed width and overflow: hidden was introduced to the CSS spec and browsers; the feature allowed us to stop trying to marry JavaScript width calculation with string width calculation and truncation. CSS ellipsis was also very friendly to...
Alternatively, you can use
ashinstead of bash.Not sure what the differences are, but I would expect parity on most standard features.
If the script is simple you can use the default /bin/sh shell.
