Man Pages
To read man pages about a shell command, enter the command in the input field. For example if you enter perl you can read 'man perl'.Some switches are useful:-f followed by a word will give a brief description,-k followed by a word will find man pages that contain the word, and a number before the word will look through that specific man section for the word.Examples:-k perl - will list perl related man pages.3 stat - will display stat (3) instead of stat (1).
