#Commands

##Files ###tail tail by default reads the last 5 lines of the input file and then exits

###awk awk is used to extract, layout and modify data using the command line (It is way more then this but its all I use it for)

###sed sed is the 'Stream EDitor' you can use to to modify files via commands and scripts using patterns, an example can be seen here

Useful Flags	Function
-i	in-place, writes the changes to the file
-f	Use a script file instead of reading the expression from STDIN
