Logfiles and config files are usually text, and a standard set of text
processing tools exist. This leads to the Unix tradition of sticking little
things together.

For example, I'm doing a 'make release' - there's a lot of repeated output,
so it's hard to see how far it's gone if it crashes. So to save the output,
I run it under the script(1) command. Then on another tty, I run

  tail -f /var/tmp/script | grep '^[>+]'

which shows the main headings of the build process.

After a while, many admin tasks start to look like text processing problems.
