RE: sed regular expression help



Yea sorry about that.  My co-worker mentioned that the underlined wouldn't come through.

The '+%D'` is what I had underlined.

I thought I had tried the regex before and it didn't work.  I just tried it again, and same thing.



sed -e "s/\'\W%D\'\`//g;/skipping/d"


BEFORE.....: `date --date=2015-01-10 '+%D'`
AFTER......: `date --date=2015-01-01 '+%D'`

Another slash?

s/match regex/replace value/options

s/\'\W%D\'\`//g

Also I didn't see anything underlined in your email. Need clarification on what you are trying to remove, to fully assist.

Thanks,
Josh
