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"
