bash uses $ character to indicate variables. for example, you can see your current environment variables with the env command. then to see a specific variable echo$var to print its value.
scripts may call variables for a variety of reasons. one common case would be collecting information from the environment it’s running under to determine whether it’s compatible.
Oh. Oh yeah, I have done that. Like for adding the date to a file name when I dump a terminal output to into a text file, or adding hit counts to a custom notification after running a scan on a cron job.
I just use the character for that. It’s fine, can’t win them all, but it’s better than having it at the beginning of every command line for seemingly no reason
I changed the $ in bash to § because fuck capitalism, keep your currency out of my free software
That’s the currency in The Sims…
How will you escape $var usage in scripts though :P
I’ve… never had to do that. What does it do?
