Conditionals (AND, OR, NOT, etc.)

if echo bazinga! ; then
	# Runs if the command didn't throw any errors (i.e. $? == 0)
fi
 
 
if [ $string ] ; then
	# Checks if string is null. If not, continue!
fi

Also else and elif like python.

AND and OR

mkdir foo && cp myfile foo

• Runs the first guy; if that was successful, run the next guy mkdir foo1 || mkdir foo2 || mkdir foo3
• Runs the first guy. The first “false” stops succeeding commands from running This is just simple logic
