Making your own commands!

[viking60]

AH OK i will jump in there and have a look. Menawhile a have found the ultimate ls alias you have got to use this one - no discussion do it!

Code: Select all

 alias ls='ls -u --color=auto --classify --time-style=long-iso --group-directories-first --si --quoting-style=shell'


It organizes the directories first and gives you colors and.... it rules

[viking60]

Oh, I see you have commented out your source the global bashrc in your ~/.bashrc.

Yes thanks! Reactivating it had no negative impact - and I still have my smiley bash prompt

From the /etc/profile.d/60alias.sh file:

# Note that you should not add custom aliases here as this file will be

# file for any added aliases.

Uh where?

Put the alias in ~/.bashrc

[viking60]

Yes I know about .bashrc (that works just fine!) but is should be put in a separate file in Mandriva apparently. I tried to make ~/.alias but no luck

[dedanna1029]

Not finding anything at the MDV forum (or in a google specified search for mandriva), either on that. If the ~/.bashrc works, I'd just use that anyway. Taking a
Edit: How to create aliases in .bashrc - Mandriva Expert. The problem is, it's very outdated.

[dedanna1029]

Should've known, my old trusty site.

Make an alias permanent

Use your favorite text editor to create a file called ~/.bash_aliases, and type the alias commands into the file.
.bash_aliases will run at login (or you can just execute it with ..bash_aliases )

Try ~/.bash_aliases

[viking60]

Will do! Gimme a minute......
No that was not it, but maybe .bash_profile......
No I give up and stick to .bashrc

[dedanna1029]

Hey, if it works, it works.

[viking60]

Berserks don't give up so I gave it another go. I want to put all my aliases in one file. For several reasons:

1 I could not remember on what boxes I had implemented what aliases so I end up writing a lot of non-working commands
2 I don't remember (- but it was good so help me out here)

So I went to .bashrc and added these lines to all my boxes:

Code: Select all

if [ -f .alias ]; then
    . .alias
fi

Then I created the .alias file in my home directory:
.alias:

Code: Select all

alias cd..='cd ..';
alias df='df -h -x supermount';
alias ls='ls -u --color=auto --classify --time-style=long-iso --group-directories-first --si --quoting-style=shell';
alias dir='ls -u --color=auto --classify --time-style=long-iso --group-directories-first --si --quoting-style=shell'
alias copy='cp -i'
alias move='mv -i'
alias cd..='cd ..'
alias orphans='pacman-color -Qtdq'
alias removeorphans='sudo pacman -Rs $(pacman -Qqdt)'
alias ping='ping -c 10'
alias lsd='/bin/ls -FAv |grep /$ | column'

Finally I "restarted" my bash like this:

Code: Select all

source ~/.bashrc

Tested out the dir command and....
It works!

Now my .bashrc is much less cluttered - hmm I wonder if that was reason No. 2 Anyway I can copy the alias file to all my boxes and have the same set of commands on them (I wonder if that was reason No. 3 )
Distro spesific aliases can be added in .bashrc and the rest is only a matter of copying the .alias file to all computers.
All aliases can be added as a line in the file ~/.alias.

[dedanna1029]

Very nice.

[viking60]

It has annoyed me somewhat that there is no ifconfig command in Mandriva.
(it has annoyed others too)
You have to:

Code: Select all

cd /sbin

and then

Code: Select all

./ifconfig

So I needed to put this in an alias so that I can run ifconfig from the CLI like I can in Arch and demonstrate the combination of several aliases into one alias at the same time.

To do this I made three aliases:

Code: Select all

alias cdsbin='cd /sbin'
alias ifc='./ifconfig'
alias ifconfig='cdsbin; ifc; cd' 

As you may notice I have combined three aliases in that last alias.
cd /sbin jumps into the /sbin directory where we need to be in order to run ./ifconfig and the cd returns us back home after the command is executed.
if I only were to use:

Code: Select all

alias ifconfig='cdsbin; ifc;'

I would remain in the /sbin directory - but we want to get back to our /home so I added the cd

I added the three lines above to my ~/.alias file so it will remain on my computer.
Now I can enter ifconfig in the Mandriva Terminal and get the same results as in Arch:

Code: Select all

There is probably an easier way of doing this. I will leave that up to our Gurus?

[rolf]

I've found that some files are in root's $PATH, not in normal user's, but don't require root privilege in order to be executed. For those commands, you can execute them as normal user by giving the full path.

Code: Select all

[rolf@localhost ~]$ echo $PATH
/usr/bin:/bin:/usr/local/bin:/usr/X11R6/bin/:/usr/games:/usr/lib/qt4/bin
[rolf@localhost ~]$ su
Password:
[root@localhost rolf]# echo $PATH
/sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin:/usr/local/bin:/usr/local/sbin:/usr/lib/qt4/bin
[root@localhost rolf]# exit
exit

So, if I follow you correctly, you could simplify your alias to just give the full path. Alternately, you could modify the user's $PATH to include these system administration types of directories. I'll leave doing that as an exercise for the padiberserks.
