sed/awk help

Hi, i've got a file composed of this kind of stuff:

python3 Solaris zone 2G-05 colt zfs syslog-ng nemo env-testing-qa1 amadeusapi cachemanager
python4 Solaris zone 1G-05 colt zfs syslog-ng nemo env-dev-qa1 apache2
python5 Solaris zone 2G-30 colt zfs syslog-ng nemo env-dev-qa1 jboss
python6 Solaris zone 2G-05 colt zfs syslog-ng nemo env-dev-qa1 amadeusapi cachemanager
python7 Solaris zone 1G-05 colt zfs syslog-ng nemo env-testing-qa2 apache2
python8 Solaris zone 2G-30 colt zfs syslog-ng nemo env-testing-qa2 jboss
python9 Solaris zone 2G-05 colt zfs syslog-ng nemo env-testing-qa2 amadeusapi cachemanager
bergman1 Solaris zone 17G-30 colt zfs syslog-ng nemo env-load-qa1 jboss

and i need to keep all words starting with env, but excluding "env-":

testing-qa1
dev-qa1
dev-qa1
...

How i can do that with sed or awk? (preferably sed)

Thanks!

i don't want to do it using cat file | awk '{ print $9 }', cause somebody can add new fields before my chosed text.

it works partially, because i've got a line like this:

depalma2 Solaris zone 2G colt zfs syslog-ng nemo env-master

it didn't keep env-master

but thx for your help!

Remove the space..

sed 's/.*env-\([^ ]*\).*/\1/' sample.txt > extract.txt

or

sed -i 's/.*env-\([^ ]*\).*/\1/' sample.txt

Open in new window
