Re: execline and $0-based stuff

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'

Re: execline and $0-based stuff

An example of my attempt, already working on at least 2 Alpine machines: > $ ls -d /etc/s6-rc/main/*getty* > /etc/s6-rc/main/getty.tty1 > $ cat /etc/s6-rc/base/getty/run > #!/bin/rc -e > exec >[2=1] > . /etc/s6-rc/bin/fn.rc > exec `{cdr $self} 38400 $name linux > $ cat /etc/s6-rc/bin/fn.rc >
