Slackware- /etc/profile? global aliases?

[Guest SDMF]

From a Mandrake 9.0/9.1 install? The part of it with the global aliases. I'm trying to get my Slackware install closer to the Mandrake one, terminal-wise, and I forgot to save a copy of my file. I want to get all the aliases set up like Mandrake had them.

here's my whole thing from 9.1

export HISTCONTROL HISTSIZE



for i in /etc/profile.d/*.sh; do

if [ -x $i ]; then

 . $i

fi

done



unset i

[Guest SDMF]

That's odd. No aliases on that. Maybe Mandrake put them in the /etc/bashrc?

[ezroller]

i dunno. I'll look.

[ezroller]

didn't see it there

[ramfree17]

for i in /etc/profile.d/*.sh; do

  if [ -x $i ]; then

     . $i

  fi

done

 

the aliases are inside the profile.d directory. the . $i line means to source the corresponding script in the directory causing whatever changes in those scripts to be reflected in the current shell.

 

ciao!

[Guest SDMF]

Hmm, that's wierd. I kinda figured that things like l (for ls) ll (for ls -l), etc. were accomplished through global aliases.

[scoopy]

In that folder is a file alias.sh

Would this be what ya lookin for?

In that folder is a file alias.sh

Would this be what ya lookin for?

YES! Slack doesn't have that file, I will add that to /etc/profile.d/

 

Thanks everyone!

[Guest SDMF]

Mods, I got the help that I needed the Mandrake /etc/profile and /etc/profile.d/alias.sh stuff, but this has developed into a problem with Slack as opposed to me asking for MDK info, so please move it to the "Other Distrobutions" forum. Thanks.

 

 

OK, so I added the alias.sh file, with a few modifications here and there so it wouldn't conflict with what was already in my /etc/profile, and all is well UNTIL I get into X. From the console, the aliases work. I also edited the "export PS1" statement in /etc/profile to alter the shell prompt, and those changes work too. Everything works, UNTIL I startx into my WM. Then none of the aliases work. In addition, I just noticed that the the shell prompt when I am in X and using a terminal has always been different from what it was from the console. It has always displayed the version of the shell followed by a $ or #. So it appears that some other script is overriding what is being set by the global /etc/profile. Have any of you experienced this same problem?

Have any of you experienced this same problem?

 

It is not a problem, it is the way bash (and other shells) work. Mandrake has the same 'problem'

 

On a login shell it is read and executed /etc/profile and the first file found of this list: ~/.bash_profile, ~/.bash_login or ~/.profile

 

On a non login shell, the config file that is read and executed is ~/.bashrc

 

So when you startx from a console you are already logged-in, aren't you? So any terminal you open within X reads and executes ~/.bashrc and don't care to look (unless you tell it) the profile files.

 

In addition aliases aren't inherited from parent sells to son shells (versus environment variables which are inherited).

 

That's why you loose your aliases when you are in X. Aliases MUST go into bashrc in order to be read each time you start a new shell (unless you do some tricks... keep reading).

 

You might think that this is a mess, but it has a lot of logic. I suggest you to google for a good and deep explanation of why is thought to be that way.

 

As you are using slakware you have to made your configuration files *almost from scratch*. I suggest to follow the mandrake schema since you want to feel like in mandrake:

 

Global files:

 

/etc/profile (plus /etc/profile.d)

/etc/bashrc (which doesn't exist in slackware, here comes the tric used by mdk to have all the users with the same profile). This file should include some code to check if we are in a login shell or not, and if we are not, then 'emulate' /etc/profile and read and execute the scripts in /etc/profile.d. For example:

    if [ "x$SHLVL" != "x1" ]; then # We're not a login shell

       for i in /etc/profile.d/*.sh; do

       if [ -x $i ]; then

           . $i

       fi

   done

   unset i

   fi

 

The user only files:

 

~/.bash_profile Should include this statement:

if [ -f ~/.bashrc ]; then . ~/.bashrc; fi

 

~/.bashrc If you want to make it work like mandrake's bash, it must include:

if [ -f /etc/bashrc ]; then . /etc/bashrc; fi

 

With the above schema, and if I'm not missing anything, you'll get the same behaviour on a login shell and in a non-login shell. This is a clever and a user friendly aproach that Mandrake uses.

 

Me, for instance, on my slackware, I don't use all that mess, I just write my user config files the way they should be written:

~/.bash_profile includes environment variables, and some code to be executed once when I login. Oh, and ofcourse a call to ~/.bashrc

~/.bashrc includes all the rest: Non global variables (ie, PS1), functions, and finally aliases.

 

As you can see, my schema is much more simple and easy to maintain

 

HTH

[Guest SDMF]

Thanks a lot, I'll do that. I would put my aliases in ~/.bashrc, but the ones I was referring to are ones that I WANT to be the default for all users.

[aru]

...but the ones I was referring to are ones that I WANT to be the default for all users.

 

As I stated above, but I think I haven't made my self clear, do it 'a la mandrake' (when I say doing it 'a la mandrake' I mean to put the 'global' alias into /etc/profile.d/alias.sh). So in order to make this stuff robust, you need to follow the mandrake schema, and that is:

~/.bashrc If you want to make it work like mandrake's bash, it must include:

if [ -f /etc/bashrc ]; then . /etc/bashrc; fi

 

Also you'll need to edit the skel (/etc/skel/) files .bashrc and .bash_profile accordingly in order that all new users will have the same pofile files with the changes in.

[Guest SDMF]

/etc/skel is an empty directory.

[aru]

no it is not, run "ls -a" to show the hidden files. Remember that files that start with a dot are hidden (such as .bashrc)
