Currently working as system administrator at Bizztravel B.V.. I've earned a bachelor degree in Computer Sciences. Since computing in general is my passion, I try to keep up with the latest development in this field. I'm active on irc.freenode.org and try to contribute to the open source community as much as I can.

comment Group by and sum in shell script without awk
@jimmij I can hardly imagine it can be done in purely sh without calling any external binary like uniq, sort etc.

Alright, so try modprobe /lib/modules/$(uname -r)/kernel/net/ipv4/netfilter/iptable_filter.ko. Also specify < when using iptables-restore

comment Grep for pattern at start or middle of a line
@LuisAntolin apart from the answer. Please remove (bash) there since the answer has nothing to do with bash. It will probably confuse novice users.
