find print only uppercase words from a file
Posted on 2007-04-06
I need a script that will extract from a file only those words in uppercase, and print only the uppercase words
example: print only those words from a Makefile that are all in uppercase
reason for script: uppercase words are typically macros in a Makefile. I wrote a one liner that will expand the macro, but am having difficulty just extracting the macros from the Makefile.
I will be using this in a Linux/Unix environment
