Inserting the script update-grub on Mageia 3 with grub 2.00

[Creto]

Hi all,

Inserting easily update-grub script on Mageia 3 with GRUB 2:00

Code: Select all

# kwrite /etc/bashrc

Você terá um arquivo como abaixo:

Code: Select all

    # /etc/bashrc

    # System wide functions and aliases
    # Environment stuff goes in /etc/profile

    # It's NOT good idea to change this file unless you know what you
    # are doing. Much better way is to create custom.sh shell script in
    # /etc/profile.d/ to make custom changes to environment. This will
    # prevent need for merging in future updates.

    # By default, we want this to get set.
    # Even for non-interactive, non-login shells.
    if [ "`id -gn`" = "`id -un`" -a `id -u` -gt 99 ]; then
       umask 002
    else
       umask 022
    fi

    # are we an interactive shell?
    if [ "$PS1" ]; then
        case $TERM in
       xterm*)
            # Inelegant fix for MGA #1623.
            PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:$(perl -le '\''use Cwd; print Cwd::getcwd() =~ s#\A\Q$ENV{HOME}\E(?=/|\z)#~#r'\'')"; echo -ne "\007"'
           ;;
       screen)
           PROMPT_COMMAND='echo -ne "\033_${USER}@${HOSTNAME%%.*}:$(perl -le '\''use Cwd; print Cwd::getcwd() =~ s#\A\Q$ENV{HOME}\E(?=/|\z)#~#r'\'')"; echo -ne "\033\\"'
           ;;
       *)
           ;;
        esac
        [ "$PS1" = "\\s-\\v\\\$ " ] && PS1="[\u@\h \W]\\$ "
        # You might want to have e.g. tty in prompt (e.g. more virtual machines)
        # and console windows
        # If you want to do so, just add e.g.
        # if [ "$PS1" ]; then
        #   PS1="[\u@\h:\l \W]\\$ "
        # fi
        # to your custom modification shell script in /etc/profile.d/ directory
       
        if [ -z "$loginsh" ]; then # We're not a login shell
       # Not all scripts in profile.d are compatible with other shells
       # TODO: make the scripts compatible or check the running shell by
       # themselves.
       if [ -n "${BASH_VERSION}${KSH_VERSION}${ZSH_VERSION}" ]; then
                for i in /etc/profile.d/*.sh; do
               if [ -r $i ]; then
                   . $i
               fi
           done
           unset i
       fi
        fi
    fi

    unset loginsh


In the end it well below "fi" insert the following line:

Code: Select all

alias update-grub='grub2-mkconfig -o /boot/grub2/grub.cfg'

Note: After inserting the line hit enter to get a blank line.

The final file should look like as shown below:

Code: Select all

fi
alias update-grub='grub2-mkconfig -o /boot/grub2/grub.cfg'

unset loginsh

Save and close

Okay, now just restart your system and do the test, recalling as 'root'

Test Result:

Code: Select all

[magomageia@localhost ~]$ su -
Senha:
[root@localhost ~]# update-grub

I hope I've been helpful to this community in some way.

this is already in the package, not as a command but it's called for every kernel updates http://svnweb.mageia.org/packages/cauld ... iew=markup

Hi leuhmanu

The command is run that way but yes:

Code: Select all

grub2-mkconfig -o /boot/grub2/grub.cfg

And the ease mentioned in the topic here is to run or type in terminal only:

Code: Select all

update-grub

As in distros using Grub the two longer users are accustomed to effecting the control in this way, for example using Ubuntu:

Code: Select all

sudo update-grub

Or in Debian logging in as root in the terminal and:

Code: Select all

# update-grub

That is the update-grub is a script for the command:

Code: Select all

grub2-mkconfig -o /boot/grub2/grub.cfg

Will managed to make me understand this time?

Creto, nice. (because I was surprised I couldn't 'update-grub')
I'll share how I do it though.
I just put in the alias entry at .bashrc
Cheers.
ps: to use it right away without logout/shutdown, ". .bashrc"

As there seems to be a demand, there is now update-grub & update-grub2 (both commands do the same) in Cauldron (from grub2-2.00-33.mga3 onwards).

It may be used as root or regular user (regular user will be asked for root password).

Thank you for bringing the GRUB 2 for Mageia 6 and also the command update-grub

Facilitating the use, as I predicted from the Mageia 3, i was a magician then?


Best regards,
Paulo Creto
