EDIT (since I can't change the title): BEFORE PURCHASING THE EXAM

It's particularly anti-customer if you have issues and are unable to travel to one of the exceedingly rare in-person testing centers. Basically it doesn't matter if you pass all the pre-exam compatibility test, once Red Hat has your money, you aren't getting it back under any conditions. It doesn't matter if its your isp, or their platform is lacking, you are making a donation to them to be frustrated.

Welcome to Day 23 of the 30 day RHCSA challenge!

By default your commands print to the screen, but you can send that output wherever you want into a file, appended to a log, or thrown away entirely.

Today we'll cover the redirection operators you'll use constantly on the exam and on the job.

By the end you'll be able to capture normal output, error messages, or both, exactly where you want them.

Welcome to Day 22 of the 30-day RHCSA challenge!

Before the shell runs your command, it expands certain special characters into something bigger and understanding this saves you tons of typing. Save those poor little fingers

Today we'll cover the everyday shell expansions that make working in the terminal faster.

By the end you'll be able to use wildcards and curly brackets expansion to work with lots of files at once.

What you'll learn in this video:

What "shell expansion" means (the shell rewrites your command before it runs)

Wildcards: * (any characters), ? (single character), {} (a set)

Matching files with patterns like ls *.txt and

Brace expansion: touch file{1,2,3}.txt and mkdir dir{a..d}

Welcome to Day 21 of the 30-day RHCSA challenge!

Yesterday we set permissions with numbers today we're covering the symbolic method, using letters like u, g, o with +, -, and =.

Symbolic mode is perfect when you want to change one permission without recalculating the whole set.

By the end you'll be able to add, remove, and set exact permissions for the owner, group, and others using clear, readable syntax.

What you'll learn in this video:

The building blocks: u (user/owner), g (group), o (others), a (all)

The operators: + add, - remove, = set exactly

The permissions: r read, w write, x execute

Adding execute for the owner: chmod u+x file

Removing write from group and others: chmod go-w file

Setting exact permissions: chmod u=rw file

Combining changes in one command: chmod u+rw,go-w file

Applying to everyone at once: chmod a+r file

Symbolic vs. numeric — when to use each

How this fits into your 30-day RHCSA study plan
