Newbie Alias and Profile questions

Newbie Alias and Profile questions

[Mike Rushton]

Can some one give me some hints about this ?

I read the documentation and can't figure this out.

I am trying to put an alias in a .bashrc

alias clear='printf "\033c"'

But what .bashrc do I put this in ?  in /ect/skel or the one my user 
directory.   I put this code in and it seems to get overwritten.
I don't understand what I am doing wrong.

It is a minor thing that i can't clear the screen, but i want to work at 
this and try to fix this.


Then I want to add a script to my profile.   but what one the .profile 
or .bash_profile ?

Other that these problems, I am converting my Korn shell scripts to bash 
under Cygwin and it is going pretty good so far.

Overwritten?  By what?  What's your home directory?

OK but 'clear' will do what you want.

Unless you want it available to all users and other shells, put it in your
.bash_profile.

FYI, at least the last 2 questions above are general UNIX/Linux questions.
You should consult a good UNIX/Linux resource for some basic user tutorials
and guides.

Can we have a moratorium on the term "newbie" please?  Please
just ask your questions.

These are all basic bash questions.  While I'm sure some kind soul will
help you further and we'll likely have a long thread discussing startup
files, you really should be investigating existing resources on the web
for bash.

Re: Newbie Alias and Profile questions

Well let me work at it tomorrow.

I know how to do this on other unix systems, just that Cygwin is not 
acting as I am used too.

I have done things like this on some versions of RHEL, UnixWare,  Xenix, 
MKS Tookit.

I guess I have to keep reading the Documentation and trying things.

( and no more use of the term Newbie :-)  )

Re: Newbie Alias and Profile questions

OK, I got it working ...  I have my home in an directory other that what 
Cygwin defaults because other software run needs

I thought my files were being overwritten ... but no - I was modifying 
the wrong files.

After I found the correct files and modified the .bash_profile 
everything was fine.

I was not aware of this .bash_profile and I was not aware of the source 
command.   On the versions of Unix/Linux that I have used
I would always do a .profile to execute the commands in it when I made 
changes.

So again I was making changes and the shell was not aware of the changes.

Hey,  I've been using Cygwin for like 2 weeks ,,,

You've been pointed to the bash man page.
It is all explained there, English on black.

As has been said already, this is NOT a Cygwin question.

clear is part of the ncurses package, so I would simply install this.

/etc/skel is a template directory for new users.

The two bash specific files you need to know are .bash_profile and 
.bashrc. Bash is different to other shells in that it will only read 
one of those two depending on whether bash is run as a login shell or 
not.

The recommended way is to source .bashrc from .bash_profile (this is 
already the Cygwin default) and to leave .bash_profile empty. Put 
everything you need into .bashrc.

Forget about .profile. It's only needed for backward compatibility 
and not an official bash file.

Sometimes 'clear' is installed and sometimes it's not, so
I put this line in my ~/.bashrc file on all Linux, BSD and
Cygwin systems:

test -z "$(type -t clear)"  &&  alias clear='echo -n -e "\e[2J\e[H"'
