rm -r *

You removed every non-folder in the current directory?

rm -rf /
is much worse

Is that the code to execute a program under Linux by any chance?

That's the shell command to make a file executable.  Otherwise:

[jl@x. dhcp.colorado.edu] ./a.out
./a.out: Permission Denied.

I was in a particularly non-destructive mood, for once.

I always use a.out for testing, unless I'm using a makefile/shellscript.

I know, it was an example  


FLAGS = -Wall
SRC = main.cc rb.cc
HEADS = rb.h
OBJS = main.o  rb.o
EXE = hw2

$(EXE): $(OBJS) $(HEADS)
   g++ $(OBJS) -o $(EXE)

$(OBJS): $(HEADS)
   g++ -c $(SRC) $(FLAGS)

run: $(EXE)
   ./$(EXE)

clean:
   rm -f $(OBJS) $(EXE)

If you have a file named "program.cc", then "make program" should compile program.cc and then link that into "program" for you. No need to ever use a.out?

To compile, I type "gcc -Wall program.c"

Ah. Maybe you should set -Wall in your environment?

Typing 5 characters is ok, and it's a habit.  Plus, I use many different computers and I don't want to forget when I use my school's/work's/etc.

Hmm, I suppose.

It's 7 more characters though :p


gcc -Wall program.c
make program
