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?
bash uses $ character to indicate variables. for example, you can see your current environment variables with the
envcommand. then to see a specific variableecho $varto 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
bingo
Was referring to https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.html#Bash-Variables
