No idea how to use mawk to emulate the behavior you describe; it
is far from being gawk. However you can refine something
looking like that, to /not/ make use of gawk:
pattern=try
grep -A1 -E "\<${pattern}\>" \
| tail -n-1 \
| mawk '{print $2}'
I get the following, if this is what you expect:
$ pattern=try grep -A1 -E "\<${pattern}\>" | tail -n-1 | mawk '{print
$2}'
Host try
IdentityFile ~/.ssh/try/id_rsa^D
~/.ssh/try/id_rsa
Feels a bit like Wily the coyote maybe, I'm pretty much certain
it can be done simpler... :-)
