RE: change all files in directory
Message ID:
When I try to run the one-liners I get:

Can't open *.cpp: Invalid argument.
Can't open *.hpp: Invalid argument.

But when I do a dir command I get:
target_functions.cpp    target_modules.cpp      global_constants.hpp
global_header.hpp       class_functions.cpp     S2b_4.opt

Clearly these files are there . . . or am I just doing something silly . . .

This can actually be done on the command-line:

perl -pi.bak -e 's/satellite/target/g' *.cpp *.hpp. *.asc

There's nothing wrong with doing it in three steps.
