It seems like this awk one-liner is better than my previous one: 

awk 'BEGIN {RS="\n}";FS=RS} /rules SNAT2VIP/ {print $1"\n}";} ' /config/bigip.conf

Hey Humphrey,

 

 

I ended up using this one liner to extract all of the monitors from the bigip.conf for a 9.x customer working on their upgrades. Just wanted to say thanks again for this gem.

 

 

In case anyone is looking for an ugly script to update 9.x monitors to make them 10.x compatible, here you go:

 

b save; awk 'BEGIN {RS="\n}";FS=RS} /monitor .*defaults from/ {print $1"\n}";}' /config/bigip.conf | perl -pe 's/(? /var/tmp/monitors.scf; b merge /var/tmp/monitors.scf; b save

 

It basically replaces \n's that don't have a preceding \r with \r\n and appends up to two \r\n's to the end of all send strings if they're not there already. The input is the bigip.conf. The output is written to an SCF file which is then imported back into memory and saved to disk with a 'b save'.

 

 

It's not thoroughly tested (yet), but should save a lot of time manually updating monitor send strings.
