grep string and then find another string
I have a file that looks like this:

Name=TOM
abcded
asdfas
fkoiaerj
inadhah
Name=Chris
23nafds
vasdkfna
afadns
afdadsfa
aaaaaa
bbbbbb
cccccc

I would to search for the string 'bbbbbb', then I would like to search above that string for the 1st occurrence of "Name" and not the other occurrences. In this case I would like the return string to be:

Name=Chris

Thanks in advance!

Tools One approach
Yes, I believe there will be other (better ?) ways with awk. But, the following is an approach that seems to give you the desired output.

Code:
> cat file165
Name=TOM
abcded
asdfas
fkoiaerj
inadhah
Name=Chris
23nafds
vasdkfna
afadns
afdadsfa
aaaaaa
bbbbbb
cccccc

> sed "s/Name/~Name/" file165 | tr "\n" "|" | tr "~" "\n" | grep "bbbbbb" | tr "|" "\n" | grep "Name="
Name=Chris

Code:
nawk -v str='bbbbbb' '/^Name=/ {name=$0;next} $0 == str { print name}' myFile.txt

Thanks for the quick response! The 'sed' command worked perfectly.

One more question in response to the 'sed' command, is there any way to reference a variable name as the search string and as the file name?

Example:

STRING=bbbbbb
FILE=file165

sed "s/Name/~Name/" $FILE | tr "\n" "|" | tr "~" "\n" | grep "$STRING" | tr "|" "\n" | grep "Name="

I think what you showed is ok. Have you tried to run with it?

My only concern would be in your variable names - I like to stay away from defining and using variable names like STRING or FILE and use instead SrchString or SrchFile. That way, you don't have to worry about over-writing some system or other variable that might be using that common word.

Yes, I tried with the variables, but no luck. I did not use the variable names that I put in the example, I just used that naming convention for description.
