Assign the result of a command to a variable in a bash script
I do not write bash scripts anywhere near often enough to recall the basics so I inevitably lose time searching for answers. In this case I failed to understand how to assign the result of a command to a variable.
All I wanted to do was assign a random number to a variable like so...
RANDOM_NUMBER=jot -r 1 2000 65000
This results in the following output when you run this script...
./my-script.sh: line 3: -r: command not found
To assign the result of the command to the variable
RANDOM_NUMBER there are 2 approaches...
Wrap the command in $() #
RANDOM_NUMBER=$(jot -r 1 2000 65000)
Wrap the command in backticks #
RANDOM_NUMBER=`jot -r 1 2000 65000`
Everyday I feel like a beginner. I found the answer here should you want to explore further.
