Help needed w/ awk command

[Imahottguy]

Hey guys and gals (again!)

I have searched forever and a day online and can't seem to find any instance of what I need. In a script, I need this:

awk '/customizedKey/ {print $3}' ezx_hardkey.cfg > temp
CODE="$(cat temp)"
awk -v shell_var="$CODE" '/shell_var/ {print $2}' list > name

Some info:

ezx_hardkey.cfg is just a file that contains a code like this:

[hardkeySetting]
carrierKey = 95ffa462-7e2f-49a9-9e6d-f8f63b2f3c40
customizedKey = ba63e2ca-089c-4a95-8e13-81522eed47a0

Once I grab that code, I store it to a var and then want to use it as the search criteria in the following awk command.

The reason being, I want to then do the following command to store the file name to the var NAME

NAME="$(cat name)"

However, I realize that I cannot use a var as the search criteria, at least in the form that I've concocted.

Is it possible to use the awk command in that manor? If not, is there another way to put this statement that I have obviously overlooked? Thanks guys/gals!

What did you expect to be in 'list' ?
You never wrote anything to it does it exist somewhere?

Sorry!! I didn't realize that...

the list file is like this:

there is only a space b/w the code and the name

[ghostdog74]

awk 'FNR==NR{a[$1]=$0;next}
     /customizedKey/{ print a[$3] }
' "listfile" "ezx_hardkey.cfg"

[Imahottguy]

Wow thank you ghostdog74! I'm @ work atm, but will test this when I get home. Would you mind explaining all of that to me? I have never seen the awk command used in such a manor, thanks!!

[ghostdog74]

1) awk '{....}' file1 file2 : awk process file1 then file2
2) FNR = current record number of the current file. FNR=0 when a new file is read
3) NR = number of input records awk has processed since its execution.
4) a[$1]=$0 : associative array. index are the first field values. Values are the whole record.
5) FNR==NR{ a[$1]=$0;next} : for every record in the first file, store in array
6) Once awk reach the last record, the second file is processed.
7) /customizedKey/{ print a[$3] } : get the third field of the second file, use it to get the corresponding value in array.
8) you know the rest.
