Just did something so stupid...

Firstly I'm learning shell scripting and I came across this example in Classic Shell Scripting

dirpath=`eval echo '${'"$envvar"'}' 2>/dev/null | tr : ' ' `

And I immediately became perplexed as to how $envvar gets expanded in between the surrounding single quotes, until 20 minutes later i realized that there are two SETS of single quotes on both sides of the double quotes.

I keep making these type of silly errors. I absolutely love learning automation, but damn that made me feel stupid. 20 minutes.....

Back at it again today. Next example in the book in much more advanced. Taking it line by line!
