When I use tail file, tail by default prints the last 10 lines.



Is it possible to change that default in the system level?

          No, but you can use alias.



          Add to your .bashrc this string:



          alias tails='tail -n 15'


          relogin at the server and try to type:



          tails file


          And you will get the last 15 lines of file

            No, the default number of lines produced by tail (and head) is mandated by the POSIX standard:




            If neither -c nor -n is specified, -n 10 shall be assumed.




            To get a different number of lines, use the -n command line option, or create a shell function:



            mytail () tail -n 5 "$@"; 


            or, if you're brave enough,



            tail () command tail -n 5 "$@";

              To do this you'd need to modify the source code and recompile it. But it looks like a waste of time and effort. Just use



              tail -n 42


              to output the last 42 lines.
