I have a key file
$ cat klist

and a data file, see example of the line below:


I need to search by key (2nd field) from klist within mlist.
My code:

Code:

 
#!/bin/ksh
cut -d':' -f2 klist|while read addr; do 
        grep "'""$addr""'" mlist; 
done
exit 0

When I run the script nothing comes out. I used set -x in the script, see output below:

Code:

 
+ cut -d: -f2 klist
+ read addr
+ grep '8855 CASA VERDE ROAD' mlist
+ read addr
+ grep '585 MOLLY LANE' mlist
+ read addr
+ grep '320 NINA ROAD' mlist
+ read addr
+ exit 0

But when I manually run one of the grep the result is found:

Code:

 
$ grep '320 NINA ROAD' mlist
N:320 NINA ROAD                   :99999 :BARROW
N:320 NINA ROAD                   :32304 :TALLAH          
A:320 NINA ROAD                   :32304 :TALLAH

I suspect the input/output streams being messed up whithin the while read loop, but have no clear understanding of the problem. Can someone clarify the situation, please?
