 |
|
Hi there,
wrote a small script because I've a problem using rsync behind a firewall.
Do you have the same problem... then this is for you 
| Code: |
#!/bin/bash
MAXDAYS=5
cd /usr
echo -n "searching snapshot..."
for ((BACKDAYS=0; BACKDAYS<=MAXDAYS; BACKDAYS++))
do
DATESTR="now -"`expr $BACKDAYS \* 24`" hours"
DAY=`date -d "$DATESTR" +%Y%m%d`
PORTAGEZIP="portage-$DAY.tar.bz2"
RESULT=`wget --spider http://www.ibiblio.org/gentoo/snapshots/$PORTAGEZIP 2>&1 | grep "^200 OK"`
if [[ $RESULT == "200 OK" ]] ; then
break
fi
done
echo -e "\tfound at today - $BACKDAYS day(s) !"
echo "downloading snapshot..."
wget "http://www.ibiblio.org/gentoo/snapshots/$PORTAGEZIP"
if [[ $1 == "clean" ]] ; then
echo -n "removing old tree"
rm -rf portage
fi
echo -n "unzipping snapshot..."
tar xvfj $PORTAGEZIP > /dev/null 2>&1
echo -e "\tdone"
echo -n "removing tarball..."
rm $PORTAGEZIP
echo -e "\tdone"
cd -

Hi...
first chanhing into dir /usr
then I download the latest snapshot on ibiblio.org to the above dir (/usr) using wget
| Code: | | wget "http://www.ibiblio.org/gentoo/snapshots/$PORTAGEZIP" |
if you run update_portage with the argument "clean", the whole portage tree will be deleted before unpacking the new one...
this results in a clean portage-tree in /usr/portage
| Code: |
if [[ $1 == "clean" ]] ; then
echo -n "removing old tree"
rm -rf portage
fi
|
then I unzip my previously downloaded using the command
| Code: | | tar xvfj $PORTAGEZIP > /dev/null 2>&1 |
now i cleanup the downloaded tarball /usr/snapshot-xxyyzz.ta.bz2 because nothing should reside in /usr (it's a little hack I know ) but it works...
this snipplet changes back to the origin-dir (where the script is startet, before the 'cd /usr')
It's tested under bash on a i686.
Hope it works

First of all thanks.
Do you want to say that this script will help instead "emerge rsync" ?

Yes... from the Gentoo-FAQ:
| Quote: |
If you're behind a firewall that doesn't permit rsync traffic, then you can instead download the daily /usr/portage snapshot from http://cvs.gentoo.org/snapshots. Just unpack the tarball (using tar xvjf portage-foo.tbz2) in the /usr directory.
|
I only followed the instructions
But my script is a little bit more powerful than the manual wget way *g* |

One problem though. From the code:
| Code: | echo -e "\tfound at today - $BACKDAYS day(s) !"
echo "downloading snapshot..."
wget "http://www.ibiblio.org/gentoo/snapshots/$PORTAGEZIP"
if [[ $1 == "clean" ]] ; then
echo -n "removing old tree"
rm -rf portage
fi |
If somehow wget in the code snippet fails (timeout during download, lost connection etc..) the portage tree will be removed, without no new file available.
The return value from wget should be checked, and continue only if OK.

Both of these URLs work and point to apparently the same directory on the webserver anyway. |
