[vox-tech] BASH: ignore space in for loop

[Dylan Beaudette]

Hi --

Can't seem to figure out how to make this BASH script do what I would like it 
to do:

I have 2 files: 

file A:
Name of place 1
Name of place 2
...

file B:
Name of place 1 [tab] code1
Name of place 1 [tab] code1
...

The "Name of place" values often have spaces in them, which seems to be 
confusing a for loop in bash:

running:
for this_quadname in `cat file_a`; do echo grep -i "$this_quadname" file_b ; 
done 

produces this:
grep -i 'Name' file_b
grep -i 'of' file_b
grep -i 'place'  file_b

...so it would seem that the for loop is iterating over both spaces AND 
newlines in the `cat file_a` expression...

is there any way to make bash only iterate over the newline characters?

thanks in advance for any ideas!

PS I am merely trying to implement a simple many-to-one join on 2 text files 
based on a common key, which is the first column in each file... however the 
spaces in the keys are messing up the conventional 'join' program...
