D-LINK DSL-500B Geracao II,

COMTREND-COMTREND CT-5072S ,
I need to extract only first word like:Thomson,D-LINK,COMTREND.Can any one help me in writing regex to this.

Hi kavyatim,

if the needed words are always the first words at the start of a new line, use this:

... | rex "^(?<myField>\w+(\s|-LINK|))" | table myField

This will get you a table of

• Thomson
• D-LINK
• COMTREND

hope this helps ...

cheers, MuS

It's a bit ugly to have the dash sometimes be part of the word (D-LINK) and sometimes serve as a word separator (COMTREND-COMTREND) - if your list of such exceptions is large then you'll have to build a large regex.
