insert hostname to logfile

insert-hostname.zsh

#### Embed the hostname into all the logfiles from a ZD ticket

This only works with ZSH and relies on glob substitution trick discussed [here](http://serverfault.com/questions/618812/zsh-substitution-cant-do-regex-with-repetition/618822#618822)

### First, get the list of files.

```
errors=(**/*console.log*)
```

Then itterate through, embedding the filename into the logfile output.

```
for i in $errors
do dbg_hostname=$( echo ${${i}%/*} | cut -d/ -f2 \
| sed 's/[^\.]*\.[^\.]*.//' ); \
awk -v dbg_hostname=$dbg_hostname '/error/{print $1 " " $2 " " "[" dbg_hostname "]"  "  " substr($0, index($0, "[error]"),1000 ) "  "   }' < $i 
done
```
## The result...
