This site, along with the manual pages, the documentations available on the
GNU project's site, and some examples on the Internet, helped me understand
somethings (not everything) related to Bash, Cat, Sed (I am still in doubt
about most of the things I've learned about Sed), regular expressions (I had
a hard time putting the pieces together), expansion types, input and output
redirection (file descriptors, command redirection etc).
This knowledge is what makes it possible for me to write a simple Bash script
called SQDownloader (https://savannah.nongnu.org/projects/sqdownloader),
although I still need to improve it.
My advice is the following: If you find some instructions on the Internet, or
anywhere else, look for informations about them before using them, and only
use such instructions if you can find relevant informations about them, and
of course, only after understanding what these instructions do.
Also, don't forget to take breaks, no human is a robot.
Best regards, ADFENO.
Have a nice day.
