25.1 Cracking the Nut
This chapter talks about the many ways of dumping a file to the screen. Most users know the brute force approach provided by cat ( 25.2 ) , but there's more to it than that:
-
Pagers like more ( 25.3 ) and less ( 25.4 ) that give you more control when looking through long files.
-
Looking at files that are compressed or otherwise unviewable (article 25.5 ).
-
Finding out what type of data a file contains before opening it (article 25.8 ).
-
Adding and deleting blank lines or other white space before displaying a file (articles 25.9 through 25.13 ).
-
Looking at just the beginning or just the end of a file (articles 25.14 through 25.20 ).
-
Numbering lines (article 25.21 ).
