Given a text file with space separated string and a tab separated integer, I'd ;like to get rid of all words that have non-alpha characters but keep words consisting of alpha only characters and the tab plus the integer afterwards.

My attempts like the ones below didin't yield any good. What I was trying to express is something like: "replace anything within word boundaries that starts and ends with 0 or more whatever and there is at least one :digits: or :punct: in between".

sed 's/\b.[:digits::punct:]+.\b//g' sed 's/\b.[^:alpha:]+.\b//g'

What am I missing? See sample input data below.

Thank you!
