Prefix all shell commands with backslashes to ignore aliases

[squatto]

I recently began using exa to replace ls. To make the switch easier, I aliased ls:

$ which ls
ls: aliased to exa --icons --classify --header --git

As a result, the command this package uses to get the latest log file (ls -t) throws an error instead of listing the sorted files:

$ ls -t
exa: Flag -t needs a value (choices: modified, changed, accessed, created)
To sort newest files last, try "--sort newest", or just "-snew"

The package uses the ls, head, tail, and grep shell commands, and they all could potentially be aliased/overwritten on the user's system. This could break the package, and there is no way of knowing because the output is suppressed:

This PR simply adds backslashes to the beginning of each shell command so that aliases are ignored and the native shell commands are used instead.

I can manually specify the escaped command with --file to get it to work, but it's janky and you'll only know to do it this way if you know why it's throwing the error in the first place:

php artisan tail --file="\`\\ls -t | \\head -1\`"

Thanks!

It seems that this PR also contains code gormatting changes, making it harder to review.

Could you remove all code formatting changes?

Oh geez, I’m so sorry! It’s a good reminder that all of my diff tools are set to ignore whitespace changes, so I didn’t even see those formatting changes 🤦🏼‍♂️ I’ll revert everything except the actual changed lines and push.

@freekmurze The unrelated whitespace/formatting changes have been reverted 👍🏻

My pleasure!
