I also discovered that the "expr" command from busybox have some regexp
support, e.g :
expr 'match' '/some/path/getty-tty1/run' '.*/getty-\([^/]*\)/run'
Exits with 0 and prints "tty1".
While this doesn't print anything and exits with 1 :
expr 'match' '/some/path/not-a-tty/run' '.*/getty-\([^/]*\)/run'
I have two other questions but I'll start proper mail threads.
