Linux

Useful commandline

List recently touched files and directories

ls -altr

List files and sort by size

ls -lS

Avoid wired characters in ls output (when redirecting to a file)

My answer on StackOverflow

The weird characters such as ^[[00m are escape characters for colorizing the output. Color output for ls is most likely enabled through an alias in your environment.

To avoid getting these color characters, you can try disable the ls alias temporarily with a backslash:

\ls *.txt

Or you can use printf command instead.

printf "%s\n" *.txt
