Did you guys know that Linux is so developer-oriented that it has a special directory called /dev/ where you're supposed to develop all your projects?

Quick Linux tip:

Use du -h to quickly see the size of everything in your current directory.

$ du -h

The -h flag shows sizes in a human-readable format (KB, MB, GB), so you can easily spot large files and directories.

Another excellent method is to utilize shell parameter expansion to replace the ":" pattern with a newline ("n") string.

Here is the syntax:
${parameter//pattern/string}

Look at the example:
$ echo ${PATH//":"/"\n"}

// denotes replacing all instances of ":" with "\n".

Quick Linux tip:

If you have trouble reading the directories in the $PATH variable, use the tr command to translate colon (":") characters to newline characters ("n") so they can be displayed in lines:

$ echo $PATH | tr ":" "\n"
