Shell script to check lines?

lpuname — Tue, 07 Jun 2011 09:09:57 GMT

Can someone help to transform the below logic into a shell script, might be easy for some of you.

I have a file with below text, I need if the line has the ":" and the above to it is not a blank line should print " : is incorrect format"

Apple:
vitamin = A
Banana:
vitamin = A

Orange:
vitamin = C

So, If I run the script on above file, it should say Banana: is not a correct format

This works for me:

awk '/:/ && stuff {print $0 "" Bad Format""} {stuff = NF}' test.txt

Cheers,
Hein

It does work on the above data file but I tried it with this data:

Apple: vitamin = A
Banana: vitamin = A

Orange: vitamin = C
Tangerine: vitamin = C

It reports both Banana and Tangerine as having bad format.

As written it is good as a pass/fail test but if you're trying to collect a list of all the errors it may need to be amended.

Just FYI.

Sorry, copy and paster error, in my test the data was formatted correctly as the author had shown.
