Formatting a header 1

[cryptoadm]

host1:Type: Intel
host1:Hostname: host1
host1:OS: Linux

host2:Type: Intel
host2:Hostname: host2
host2:OS: Linux

host3:Type: Power
host3:Hostname: host3
host3:OS: AIX

Partial file looks like above and I want the hostname before the host section and the hostN: gone.

Thanks!!

For example:

host1
Type: Intel
Hostname: host1
OS: Linux

host2
Type: Intel
Hostname: host2
OS: Linux

host3
Type: Power
Hostname: host3
OS: AIX

Hi

awk 'NF&&(!l||$0!~"^"l){l=$0;sub(/:.*/,"",l);print l}{sub(/[^:]*:/,"")}1' /input/file

Tested with [tt]gawk[/tt] and [tt]mawk[/tt].
