The command "julia -e '${julia_code}'" is used to run a Julia program from the command line, where '${julia_code}' represents a placeholder for Julia code.
The '-e' option in the command stands for 'eval', which allows you to evaluate a string of Julia code directly from the command line.
When you execute this command, the placeholder '${julia_code}' is replaced with the actual Julia code you want to run. For example, if you replace '${julia_code}' with 'println("Hello, World!")', the command becomes "julia -e 'println("Hello, World!")'".
So, this command is useful if you want to run a short segment of Julia code without creating a separate Julia script file. It allows you to quickly execute Julia code from the command line without the need for a complete Julia program.
