# When I read source files I often stumble upon big headers containing copyright information and other info. 
# Scrolling through multiple files with such headers is really frustrating when all I want is to read, not modify.
# So I developped this script to clear out those headers only to make convenient READING the sources. 
# Of course, make a safe reading copy before proceding with this.  

# It scans the first 20 lines (change to whatever you like) and deletes all the lines starting with //.
# It stops at the first encounetered hash sign, which signify the first includes. 

awk -i inplace '!( NR<20 && !/^[[:blank:]]*#.*)/ && /^[[:blank:]]*($|[/].*)/)' file.c

# So I would use find to get all my C++ files
find . -regex ".*\.\(c\|cc\|cpp\|cp\|cxx\|c++\|h\|hh\|hpp\|hxx\)"

# and then just combine the commands
find . -regex ".*\.\(c\|cc\|cpp\|cp\|cxx\|c++\|h\|hh\|hpp\|hxx\)" \
-exec awk -i inplace '!( NR<20 && !/^[[:blank:]]*#.*)/ && /^[[:blank:]]*($|[/].*)/)'  {} \;
