Using head you can find out quickly what's in a file by viewing the top few lines.


 


To view the beginnings with head:



head filename

At the shell prompt, type head followed by the filename.  By default you'll see the first ten lines on the screen.  


 


 


To view a specified number of lines:



head -20 filename

Add -20 (or whatever number of lines you want to view) to view a specific number of lines


 


 


To view the beginnings of multiple files:



head filename* | more

You can view the tops of multiple files by piping head (plus filenames) to more.
