Sometimes you have need to backup installed packages. I realize most port
management tools do this automatically, but if you're on a system with a lot
of packages installed and one port management tool fails and you use another
to fix it, /usr/ports/packages can become jumbled. Anyways, I've written a
simple python script which will create a fresh snapshot of all installed
packages. These are convenient for backups or installing on a new system.
For anyone interested:
from subprocess import Popen, PIPE
import os
s = Popen('pkg_info -a | grep : | grep
Information',shell=True,stdout=PIPE).communicate()[0]
pkg_location = '/data/packages'
packages = []
for line in s.split('\n'):
info = line.replace('Information for ', '').replace(':','')
packages.append(info)
os.chdir(pkg_location)
for package in packages:
s = Popen('pkg_create -b ' +
package,shell=True,stdout=PIPE).communicate()[0]
