небольшая программа на AWK для приведения файлика dhcpd.leases в читабельный вид

awk ' { out = ""} \
{ $1=="lease"||$1=="client-hostname" ? out=" " $2 : out=out } \
{ $1=="binding"||$1=="hardware" ? out= " " $3: out=out } \
{ $1=="ends"? out=" " $3 " " $4: out=out } \
{ $1=="}"? out="\n": out=out } \
{ printf out," " }' dhcpd.leases \
| grep active \
| sed -e s/'[{};" ]'/\ /g  \
| awk '{ printf "%-15s %-17s %-10s %-5s\n", $1, $5, $2, $3 }'
