Using global aliases in Slackware

First way:
In /etc/profile I just added alias hello="yes hello" doesn't work

Second way:
I made a file /etc/bashrc and put hello="yes hello"
And I edited /etc/profile like

Code:

#import /etc/bashrc to this file



if [ -f /etc/bashrc ]; then

        . /etc/bashrc

fi

But not working either

How to set aliases globally? ,not per-user

Use alias command before parameters, for example:

Code:

~$ alias hello='yes hello'

Then you check alias by invoking cmd:

Code:

user@system~$ alias

OR

user@system~$ alias <alias_name>

user@system~$ alias hello

Similarly, add the same cmd in ~/profile or ~/.bashrc. For global setting, do the same in /etc/bashrc or /etc/profile. Then source .profile or .bashrc and check it again.

Code:

user@system~$ source .bashrc

OR

user@system~$ source .prifle

Oh, sorry those were typing errors

I already had written alias before parameters

not working..

Seems that those global files i.e. /etc/profile or /etc/bashrc ain't working in your case, because whenever your work, by default your own (per user) files are used (if they are available), not the global files. So you can do one thing: Define the same alias in your own files (~/.profile or ~/.bashrc) and check whether it work or not. Else, temporary move your ~/.profile or ~/.bashrc to some other place, logout from your session, and then login again and check those alias, bacause in that case system will read profile settings from global files.

Thanks but partially worked..

aliases are applied only in the case of ~/.bashrc

Only thing I have to do is make it global

It seems like slackware's problem

What exactly did you do? Just add the same lines (i.e. alias hello='yes hello') in both /etc/bashrc and /etc/profile. Source these files and check it. Also, as far as I am concerned, each user will need to re-login to take changes into effect. Moreover, if it partially work, then append following entry in user's ~/.bashrc and ~/.profile file:

Code:

source /etc/profile

source /etc/bashrc

Note: After any change, source the file to take changes into effect.

When I typed source /etc/profile the alias was applied

But when I log off and log on , the alias was not applied

Well.. I guess Slackware doesn't use source command when logging on

From /etc/profile in Slackware 14.1

Code:

# Append any additional sh scripts found in /etc/profile.d/:

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

  if [ -x $profile_script ]; then

    . $profile_script

  fi

done

So, add your custom aliases to files (one for csh and one for bash) in /etc/profile.d/ and make them executable.

thanks I did as you said

/etc/profile.d/hello.sh

Code:

#!/bin/sh

alias hello="yes hello"

/etc/profile.d/hello.csh

Code:

#!/bin/csh

alias hello

When I reboot

The alias worked in tty very well

But in the terminal of xwindows

not working

Is this correct?

That seems odd. I see the aliases defined in the /etc/profile.d/coreutils-dircolors.(c)sh files in my terminals in X.

Try creating a .bash_profile (as well as .bashrc) in your home directory, works for me:

Code:

if [ -f ~/.bashrc ]; then

  source ~/.bashrc

fi

According to this, aliases should work globally if they're in /etc/bashrc.

The problem is that when a terminal is started in X, it is started as an interactive shell that is not a login shell. This means that at startup, bash reads commands from ~/.bashrc. (Read the INVOCATION section of 'man bash').

In my ~/.bashrc I have:

Code:

. /etc/profile.d/coreutils-dircolors.sh

so the aliases are loaded.

If you were to do this generally for all users, you could look at creating a .bashrc file in /etc/skel so that when a user was added, a default ~/.bashrc was added. The default .bashrc could contain:

Code:

if [ -f /etc/bashrc ]; then

  source /etc/bashrc

fi

Then /etc/bashrc could be created to provide the aliases to all users.

Thanks for all your replies

Now I get it

I did like this:

In /etc/bashrc I added my aliases

And in ~/.bashrc add this code

Code:

if [ -f /etc/bashrc ]; then

  source /etc/bashrc

fi

Finally I copy ~/.bashrc to /etc/skel
