How can i add an ip address and mac adderess of the ifconfig command to a file?
I konow that awk solves the problem but how.
my archive is /tmp/armd
somebody told me to use sth like this:
awk -vval=$( ifconfig eth0 | grep "inet addr" | cut -d" " -f1 ) 'BEGIN{v2=val} { if (NR==1) {print $0" "v2} else print; }' /tmp/armd
what i want is this:
i have this archive /tmp/armd:
asdmpo sdmpm pnsad
pomsd osndsd snsdoni
and what i need is this:
asdmpo sdmpm pnsad 192.168.100.1 00:09:6B:5F:4EB
pomsd osndsd snsdoni 192.168.100.1 00:09:6B:5F:4EB
Oh I see.. you might be able to use the column command, not sure, never really used it myself or you could craft up a perl script to manipulate the data in the order that you desire.
i want to lern more about it. How can i delete addr: an put a blank " ". This is the output:
# awk -vval="`/sbin/ifconfig eth0 | awk '/inet/ {print $2} /HWaddr/ {printf $5} ' | sed 's/adr:/ /' `" '{printf $0" "; print val}' /tmp/armd5
