06 Nov 13 Getting EMC disk ID’s.
We want storage to check performance on three possibly problematic LUNS.
Need to get the 4 character LUN ID’s on three disks:
disk82 disk83 and disk123
/usr/bin/inq -nodots -sym_wwn | egrep “disk82|disk83|disk123″| awk ‘{print $3}’ |awk ‘{ print substr( $0, length($0) – 3, length($0) ) }’
Output:
5422
5423
5826

A good day is an awkful day.
30 Nov 10 awk trick of the day. Parsing comma delimited input to a sequential file
Lets say I have a list of servers a mile long to visit. Got a help desk request with the servers listed separated by commas.
server1,server2,server3
Lets say It is actually about 30 or 40 servers and I’m too lazy to edit the list
echo “server1,server2,server3” > olist
awk -F, -v nr=1 ‘{ for (x=nr; x<=NF; x++) {printf $x ” \n”; }; print ” ” }’ olist
Output:
server1
server2
server3
Plug and play time here, you can take care of any delimited format like this.
