CSC362.L02, Lab 3: Regular Expressions

Admin:
* Sorry to see so few of you at the summer research session

Topics:
* Search for strings using grep

Notes:
* grep matches *anywhere* in a line.  To tie to the beginning of the line, start the regular expression with ^
* In our version of grep, [A-Z] is *not* capital letters.  Read the man page for details.
  * Use a different regular expression [ABCDEFGHIJKLMNOPQRSTUVWXYZ]
  * Or use Unix command: export LC_ALL=C
* To use the funky curly brace variants, you need to use egrep rather than grep
