Ok here it goes me and my teacher of my linux class at school both have different options on this i say it can be done but he said that it cant but i cant prove him wrong so i hope you guys can help.

what we need to do is write a shell script that creates a user and adds the $HOME variable to the PATH Statement for that user

I know how to do it with out a shell script but i dont know how to make a shell script do it any help would be welcome

Do it manually.

Load ~/.bash_history into your favourite editor.

Remove all lines that didn't have to do with your
process ...

insert
#!/bin/bash
at the top

replace the bits where you typed the username
with a $1

save it as:
create.sh

chmod +x create.sh

Cheers,
Tink

sorry but i dont understand what you mean is there any other way to expain it

Thanks

You said you knew how to do it manually.

And I suggested to do that, and then turn
what you did into a bash-script afterwards.
Which bit did you not understand?

Cheers,

Which file are you trying to edit, what
are you doing from the command line
to do so?

You can use sed/awk to edit streams
(e.g. piping the file through them).

rocket go looks like a newb that hasn't discovered pico/nano.

keep going to class and don't have meaningful discussions with your "linux teacher"

Thanks, but I don't :}

I think what he meant is that from the shell
he would edit /etc/passwd and ~/.profile
using vi or something to that effect, and
he doesn't know how to do e.g. vi from
a script (which is fair enoough ;}) ...

yes thank you Tinkster i know there is a way to use vi to edit a file in a shell script but i cant get it to work

Use awk or sed then.
Or tell me what you want to achieve?
Like in what the expected result would be?

Cheers,

rocketgo. Dude.

If you can do it manually then you can do it in a shell script... just post here what the manual steps are and Tinkster, myself or someone will show you what you need to change/do to make it work in a script... I'm always eager to prove the teaching establishment knows less than it should
