Raku: what is the syntax for shell calls with spaces?
In Raku, you can make shell calls with spaces by using the shell
function or the run
routine with proper quoting. Here's an example of the syntax:
- Using the
shell
function:
rakushell('command with spaces')
You can pass the shell command as a string to the shell
function. The command will be executed in the system shell.
- Using the
run
routine with quoting:
rakurun("command", "with", "spaces")
You can pass each part of the command as separate arguments to the run
routine. Raku will take care of properly quoting the arguments when invoking the shell.
If you need to pass arguments with spaces to a shell command, you can enclose the argument in quotes. For example:
rakushell('command "argument with spaces"')
or
rakurun("command", "argument with spaces")
In both cases, the argument with spaces is enclosed in quotes to ensure it is treated as a single argument by the shell.
Remember to properly escape any special characters or meta-characters if needed, depending on the specific shell command you are executing.
It's important to exercise caution when executing shell commands, especially when dealing with user input, to prevent potential security vulnerabilities like command injection.
