Text Processing:
The rich set of text processing command(s) is comprehensive and time-saving. Knowing even their existence is enough to avoid the need of writing yet another script(s) (which takes a lot of time and effort plus debugging) – a trap which many beginners fall into work with. An extensive list of text processing commands and relative examples can be found here
Basic Utilities:
More was the original file pager
Less was developed to offer some more advanced features
As a reaction to that, more was developed a bit more
But still, to do more, useless
Use head to show the first 10 lines of a text file
Use the tail to show the last 10 lines
Use –n ** to specify another number of lines
Cat shows text file contents of the screen
-A shows all non-printable characters
-b numbers lines
-s suppresses repeated empty lines
Tac is doing the same as the cat , but in the reversed order
