UNIX for Dummies Questions & Answers

Hey guys & gals,

I am hoping for some advice on a sed or awk command that will
allow to only print lines from a file that contain 3 numeric values.

From previous searches here I saw that ygemici used the sed command
to remove lines containing more than 3 numeric values ;
however how would one best be able to combine the above to remove lines
that do NOT contain 3 numeric values ?


so basically, requirement would be that from the below list;
only abc123 would be printed.


Any help greatly appreciated !


Thanks - TAPE

See if this works for you:

Code:

sed -n -e '/[0-9]\{4,\}/d' -e '/[0-9].*[0-9].*[0-9]/p' File

Code:

nawk 'gsub("[0-9]","&",$0)==3' myFile

Both the above options seem to work great !

Thanks Shell_Life & vgersh99, your expertise greatly appreciated !

I have now ordered a book on sed / awk ... its about time I get better at this stuff

Thanks again !
