Command Aliases???

UFCfighter · 07-11-2006, 08:38 AM

Does anyone know where command aliases in SLACKWARE go? Using the alias command, aliases are gone after logout. Where do global aliases vs. user aliases placed? I would appreciate the help, thanks.

Local aliases should be placed in ~/.bashrc and global ones in /etc/bashrc

Thanks for the reply, but I don't have a .bashrc in my entire system. Is this something that I can just create, or could aliases be placed elsewhere? Thanks.

You should just be able to create one and have it working, bash is very easy going =)

If your login shell is bash you should have it in your home dir and a system one in /etc (maybe called bash.bashrc) if not loon in /etc/profile

I created the files in a few places to try it out. First, I created etc/.bashrc. Then I tried home/user/.bashrc, usr/.bashrc, and a few other places. None of them worked.

Thanks for the help. There is a file etc/profile, and I tried adding ALIAS XX="XX -X", but it didn't work. I also tried xx = "xx -x" but still didn't work.

in the /etc dir the file is called either /etc/bashrc (no leading dot) or /etc/bash.bashrc

What is the cpntense of your /etc/profile file?

Ahh, I see, we still have some problems.

Basically ya gotta set up the system ...

The system is as follows:

/etc/profile --> $HOME/.bash_profile --> $HOME/.bashrc --> /etc/bashrc

If you don't already have $HOME/.bash_profile, then create it and make sure it contains the following:

Code:

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

Then, in $HOME/.bashrc make sure the following exists:

Code:

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

This will preserve your aliases when you su from user, and allow alises to crop up when you use an xterm.

I realise it's not exceptionally clear, but the explanation is long and i'm tired =)

no bashrc, .bashrc, bash, .bash, etc...

You probably aren't using bash. When you type at a commandline

echo $SHELL

what do you see?

If you are using csh or tcsh, then your shell startup script is .cshrc
You can add aliases there.

eg.
alias dir 'ls -lash'

(Note different syntax from Bourne shells.)

I have aliases working with bash with an executable file that I called aliases.sh in /etc/profile.d dir
then you need to be sure that your aliases will be loaded anyway, either if your shell is a login one or not.
To solve this I create .bashrc in my home
[code]

[ -f /etc/profile ] && . /etc/profile
[ -f /etc/bashrc ] && . /etc/bashrc

[\code]

It executes the files in /etc/profile.d, loading also your aliases

You can make them, there is no problem doing that. If you don't have the file ... write it.

I like sbabaro's solution to aliases - very neat, very Slackware.

UFCfighter · 07-11-2006, 09:59 AM

I'm using bash, but I don't have the files that people say I should have. This was a straight install of Slackware 10.2.

sbabaro · 07-11-2006, 10:19 AM

as piete said, create it!

The only files that you have in a fresh Slack is /etc/profile and /etc/profile.d (with several scripts inside)
The others you need to create by yourself
Use your favorite editor and write it down the file using one of the solution shown in this thread
