[SOLVED] How do I create aliases?

[michel]

I know I can look it up, but since we are on the subject :-) how do you go about creating aliases and what is the su alias you both agree to.

I think also you can make the file ~/.bash_aliases and have them in their , will test this now ,

Take a look at your .bashrc file. You will see:

# Alias definitions.# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.


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

When present in your home directory. the .bash_aliases file will be used. It is better to put your custom aliases in this file, rather than adding them to .bashrc.

Creating the .bash_aliases file is simple. Just use your favorite text editor and save it as .bash_aliases (note the leading period). The syntax for a basic alias takes the form:


alias name=command

This means that name is an alias for command. Whenever name is typed as a command, Bash will substitute command in its place. Note that there are no spaces on either side of the equal sign. Quotes around command are necessary if the string being aliassed consists of more than one word.

yes this is working out just fine ......did not even half to log out after making the .bash_aliases file with one alias per line ,just close and reopen the terminal .

You don't even have to do that. If you edit .bash_aliases while in a console, when finished and the file is closed, just type:

source ~/.bash_aliases

I make that an alias.
alias reload='source ~/.bashrc'

[Snowhog]

Mine is: alias ua='source ~/.bash_aliases'

Most of my aliases use less keystrokes (saves time) than the actual command.

I try to do that to, but more importantly I need something I can remember. reload is easy to remember and is still shorter that the original command. I used to try to make very short commands, but couldnt remember them and got confused alot.

[Snowhog]

One I use a lot, and in my .bash_aliases, is:

alias a='clear && alias | more'

[kubicle]

what is the su alias you both agree to.

The immediately apparent difference between 'sudo -sH' and 'sudo -i' is the $PWD, the former keeps the current working directory (comparable to 'su') while the latter switches to root's home directory (comparable to 'su -', 'su -l' or 'su --login')...of course you can set an alias for both.

Thanks for the clarifications I get most of it except the saving as .bash_aliases if you could give a concrete example I would appreciate it.

Thanks to all the other feedback and clarifications.
