basic stuff

Moving stuff from one place to another

Chaining commands and outputs(stdout):

| # this is a pipe
> # this is a redirect

Moving stuff more conventionally:

cp SOURCE TARGET # you can't chain to cp though.
mv SOURCE TARGET # moves (or renames!)

Search for stuff

WHATEVER | grep KEYWORD OR PHRASE

# e.g:
ls -a | grep .md # list all markdown files in a folder.

Comparing stuff

diff -s file1 file2

# Confirmation when same + ignoring whitespace + comparing recursively / entire folders + side-by-side view:
diff -swry file1 file2

Disabling case sensitivity for bash using ~/.bashrc:

bind 'set completion-ignore-case on'
