 Posted: Tue Aug 01, 2006 1:15 am Post subject: Update Script |
 |
|
Hello,
I am a gentoo user of 2 months and I am very happy with it.
I update every week or so, and always need to look up the commands. So, I thought I would try my hand at Bash scripting the update process. This very simple script is my first.
The emerge commands are not functional, they only echo to the terminal. The echo need only be removed to make it functional.
Any comments are welcome, on the concept, the scripting, or the emerge flags I am using.
Thanks,
Brett
| Code: | #!/bin/bash
#---------------------------------
echo "This script will update your system."
echo "The following commands will be issued:"
echo " emerge sync"
echo " emerge -pvDuN world"
echo " emerge -vDuN world"
echo
echo "You will be prompted before each procedure"
echo
#---------------------------------
super_user="root"
if [ $USER = $super_user ] ; then
echo "Logged in as root, proceding"
else echo "You must log in as root to quick-update"
exit
fi
#---------------------------------
check_with_user ()
{
X=0
while [ $X = 0 ]
do
echo "Continue with update (yes/no)?"
read go_on
if [ $go_on = "yes" ] ; then
echo "Continuing with update..."
echo
X=1
elif [ $go_on = "no" ] ; then
echo "Exiting, update not completed."
exit
fi
done
}
#--------------------
echo
echo "Ready to begin emerge sync."
check_with_user
echo
echo "emerge sync"
#--------------------
echo
echo "Ready to pretend emerge -vDuN."
check_with_user
echo
echo "emerge -pvDuN world"
#--------------------
echo
echo "Ready to emerge -vDuN."

You can simplify your script by using portage's --ask option...
| Code: | | emerge -DuavN world |
It will give you a prompt of yes or no. |

You should add a revdep-rebuild option; my lazy script is something like this:
| Code: |
#!/bin/bash
emerge --deep --sync
emerge system
revdep-rebuild
emerge -uDN system
revdep-rebuild
emerge world
revdep-rebuild
emerge -uDN world
revdep-rebuild
|
I run it at the end of the day; and check it in the morning. |

Hmm...
A request for feedback on a Bash script whose function is related to portage.
Portage and Programming or Unsupported Software?
I choose Portage and Programming. The intent was to get feedback on the bash scritpting as this was my first attempt at it, more than it was to release a script for general use. That said, I used this to update my system last night and it worked quite nicely. I think I will keep it around.

Your script looks good but I'm not sure it's really neccessary.
I have emerge --sync as a nightly cron job and that only leaves the emerge -auDvN world as the sole command I need for when I'm ready to update.
This makes sure your portage directory is up to date and only requires one command when you're ready.
