Wrench Segregate file content using sed backreference
I have some text like
Code:
EU1BTDAT:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD'
EU1BTDATEST:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD'
EU1CLOSEDATES:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD'
EU1DATED:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD'
EU1DATED.022415:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD'
EU1DATEM:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARDM'
EU1DATENYSE:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD'
EU1DATEQTRLY:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARDQ'
EU1DATEQTRLY:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD'
EU1DATEQTRLY.010416:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARDM'
EU1DATEQTRLY.010416:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD'
EU1DATEQTRLY.orig:ASSGNDD filename='$SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARDM'

i want to fetch the 1st word before ":" and the last word after "=".
I believe it can be used using sed back reference.

I have tried using
Code:
sed -e "s/([a-z]*)(:)(*)(=)(*)/\1 \4/g" backreftext

but it does not work
also i have tried by adding escape characters.. but veil.
if anyone can help and suggest where i am going wrong.

The output expected as :
Code:
EU1BTDAT $SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD
EU1BTDATEST $SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARD
EU1DATEQTRLY $SEQFILES/SUNIA.PJ008202.CARDLIB/DATECARDQ
