I am god.

bash% chmod +e jigsaw.
Jigsaw has been executed

[Hitmen]

rm -r *

whoops.

[iago]

rm -r *

whoops.

You removed every non-folder in the current directory?

rm -rf /
is much worse

[Meh]

chmod +e jigsaw.
Jigsaw has been executed

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

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

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

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

a.out? Ewww...

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?

[iago]

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

[Adron]

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

[iago]

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.

[Adron]

Hmm, I suppose.

It's 7 more characters though :p
