Last night, before abandoning my computer for the evening, I started a bunch of compiler jobs so they'd be ready in the morning, using
make -f alpha.mak &>alpha.out &. When I came back and hit return, I saw the following output:
 Done make -f alpha.mak &>alpha.out - Done make -f beta.mak &>beta.out + Done make -f gamma.mak &>gamma.out
My question: What do the
- symbols mean in that output?
I'm using bash on RedHat 6.
