# == REPO COMMANDS
|
||||
# Use a command that will fetch the current version of voxelands in a repository.
|
||||
# The next tidbit is from Frugalware docs: http://frugalware.org/docs/stable/makepkg.html#_a_simple_example
|
||||
# Which is licensed under the standard GNU free documentation license: http://frugalware.org/docs/license
|
||||
#
|
||||
# lynx -dump http://www.kyz.uklinux.net/cabextract.php |grep 'cabextract source code' |sed 's/.*-\(.*\).t.*/\1/'
|
||||
# Usually the command consists of three parts: a lynx -dump someurl, a grep foo, and a sed command. We use the http protocol
|
||||
# if possible, but sometimes we have to use ftp. In that case instead of lynx -dump you should use wget -O - -q.
|
||||
# Of course, you could use wget all the time, but lynx is simpler. The sed command could be replaced with the combination
|
||||
# of tr and cut if you prefer them instead of sed. The example used above would be the following with cut and tr:
|
||||
# lynx -dump http://www.kyz.uklinux.net/cabextract.php |grep 'cabextractsource code'|tr -s ' '|cut -d ' ' -f 6
