Linux: Display / Show File Contents (tabs, line breaks, non-printing characters)
I write before guide, howto create file on Linux shell / command line without text editor (with cat command) and this is guick tip howto display / show file contents (tabs, line-breaks, non-printing characters (ASCII control characters: octal 000 – 037)) and display all on Linux shell / command line. This is very useful when you want to know the entire contents of the file.
Example file I use /tmp/testing.
