[RFC PATCH v2] Configure the Node a routable ula v6

[Peter J. Philipp]

Hallo,

something | grep -v condition1 | grep -v condition2 | something

kann auch geschrieben werden als:

something | grep -v -e condition1 -e condition2 | something

und man spart sich warscheinlich speicher.  Hier ein test auf Mac OS X für demo:

spica:~ pjp$ cat list
1 cars
2 property
3 hookers
4 monkey
5 typo
6 money
spica:~ pjp$ grep -v -e typo -e monkey list
1 cars
2 property
3 hookers
6 money

:-)

Gruß,
-peter
