Don't do people's homework assignments!

It is against the Unix forum policy and just encourages them to keep coming back and continue posting homework problems to be done by the very helpful and well meaning people here.

To those posting your homework, you're not learning anything by doing that. If your response is that you don't want to learn this stuff, then reconsider the career path that you are on that would require you to take courses and learn things that you inherently aren't interested in. It is a sad existence that you are setting yourself up for.

To those that help these people, consider that someday you will have to hire someone with Unix scripting experience. Would you prefer to have someone who has actually struggled with the vagaries of scripting in Unix/Linux, who asked for and learned from the help they received when they got stuck, or do you want someone who posted all their homework to some web forum so someone else could do all the work and they learned nothing. I guess what I am saying is that you are setting yourself up (or one of us) for that situation.

And it will SUCK!

Look, I know that scripting in Unix isn't easy. Programming is an inherently challenging task. Using Unix and Linux to do real work is tough. I love these forums because they are full of very helpful people working together to solve real problems in their everyday lives.

That is awesome!

But, please, use some judgement. KevinADC is right. Just looking at some of the questions that are posted here makes it easy to spot the simple homework problems.

If nothing else, help the students, but do it in a way that makes them learn. Ask them what they have tried first. Have them post their code and output. Guide them to the correct answer instead of just handing it over.

Just my 2 cent rant for the day.

SYSTEMD-DEBUG-GENERATOR(8)				      systemd-debug-generator					SYSTEMD-DEBUG-GENERATOR(8)

NAME

       systemd-debug-generator - Generator for enabling a runtime debug shell and masking specific units at boot

SYNOPSIS

       /lib/systemd/system-generators/systemd-debug-generator

DESCRIPTION

       systemd-debug-generator is a generator that reads the kernel command line and understands three options:

       If the systemd.mask= option is specified and followed by a unit name, this unit is masked for the runtime, similar to the effect of
       systemctl(1)'s mask command. This is useful to boot with certain units removed from the initial boot transaction for debugging system
       startup. May be specified more than once.

       If the systemd.wants= option is specified and followed by a unit name, a start job for this unit is added to the initial transaction. This
       is useful to start one or more additional units at boot. May be specified more than once.

       If the systemd.debug_shell option is specified, the debug shell service "debug-shell.service" is pulled into the boot transaction. It will
       spawn a debug shell on tty9 during early system startup. Note that the shell may also be turned on persistently by enabling it with
       systemctl(1)'s enable command.

       systemd-debug-generator implements systemd.generator(7).
