The third column has a value in the first row but not the rest. Do you want to delete the third column in all but the first row?– John1024Commented May 7, 2014 at 6:18

I can help you with an awk command for this operation, but tell me this: Will the second line always be representative of the rest of the following lines?– bgStack15Commented May 7, 2014 at 15:43

Yes the second line and subsequent lines will have no values in column 3.– user1988900Commented May 7, 2014 at 16:08

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
