Hi again!
I'm running a stable (x86) gentoo install, but sometimes (often?) I want to emerge some unstable (~x86) packages. If I only know the package names but not the categories (e.g. net-www) I have to search for it and add it to package.keywords. I wrote this small script to do all the work by using locate and sed.
As root save it to e.g. /usr/local/bin/unmask.sh and change ARCH at the beginning of the code as needed (e.g. ~x86 for me), then do a chmod u+x unmask.sh.
Now you can use it like this:
unmask.sh <PACKAGENAME>
or
unmask.sh <CATEGORY>/<PACKAGENAME>
- It checks if the entry is already present
- If there is more than one package with the same name it tells you and you can use the pattern <CATEGORY>/<PACKAGENAME>
- It does a backup 
| Code: |
#!/bin/sh
ARCH="~x86"
echo "Searching in portage tree..."
if [[ $1 =~ '.*/.*' ]]
then
result=`locate -i -l 0 -r /usr/portage/$1/ChangeLog | sed -e 's#/usr/portage/##' -e 's#/ChangeLog##'`
if [[ $result =~ '.*/.*' ]]
then
if [[ `cat /etc/portage/package.keywords | grep -i "$result " ` ]]
then
echo "Error: Already in list!"
echo -e $result
exit 1
fi
echo "Adding $result to package.keywords"
echo "$result $ARCH" >> /etc/portage/package.keywords
echo "done."
cp /etc/portage/package.keywords /etc/portage/package.keywords.backup
else
echo "Error or not found!"
echo -e $result
exit 1
fi
else
result=`locate -i -l 0 -r /usr/portage/.*/$1/ChangeLog | sed -e 's#/usr/portage/##' -e 's#/ChangeLog##'`
if [[ $result =~ '.*/.*/.*' ]]
then
echo "Error: Ambiguous results:"
echo -e $result
exit 1
elif [[ $result =~ '.*/.*' ]]
then
if [[ `cat /etc/portage/package.keywords | grep -i "$result " ` ]]
then
echo "Error: Already in list!"
echo -e $result
exit 1
fi
echo "Adding $result to package.keywords"
echo "$result $ARCH" >> /etc/portage/package.keywords
echo "done."
cp /etc/portage/package.keywords /etc/portage/package.keywords.backup
else
echo "Error or not found!"
echo -e $result
exit 1
fi
fi

I know this is just dirty and I`m almost sure there is something better around here (although I haven't found anything) but this is working perfectly for me so it might also help somebody else! Don't blame me if your computer explodes! |
