A Self Help Guide to Bash
If you've ever used Bash and felt the need to see a therapist afterwards, then read this, because it will save you the money.
Note: I've abandoned this guide. I'm working with F# on distributed systems and my efforts will go in that direction.
a confession
I had trouble learning Bash. I found that I could never remember how to write simple things like an if statement.
hello world
There can’t be a space between the variable name and the value. Why? Because whenever Bash sees a space it thinks that the text preceding is the start of a command, and tries to run it
if statements
This isn’t how other languages work. What’s going on? The reason is in the grammar of the if statement. The stuff that follows the if has to be a command.
