How to extract ID and device file

[Sandman!]

Did you try the awk construct I have posted? It does exactly what you're looking for viz., print the device ID followed by the device filename on the same line and it excludes the alternates.

Ah, you do want all and not just 'grep' for one. Try:

$ perl -nle '$dev=$1 if /^Logi.*\[(.*)\]/; if ($dev && /\s(c\d+t\S+)\s/) { print "$dev $1";$dev=""}
' devices.txt


$dev=$1 if /^Logi.*\[(.*)\]/; # remember stuff between box if line starts with 'Logi'
if ($dev && /\s(c\d+t\S+)\s/) # If we have a device and it looks like a 'ctd' on line
{ print "$dev $1";$dev=""} # print and clear device.

sandman,

Tried your method by simply copy and paste but didn't return anything.

awk '/device/{x=z[split(y[split($NF,y,"[")],z,"]")-1]};/active alive/{print x,$3;exit}' file1.out

Thanks a bunch to James for simple solution - one liner!!!
