I have a data file with some white spaces:

file.txt

102436350   000007660809        000007660809        000CLPCCNMN10

I tried this:

grep ${acc} ${fxc} > registro
IFS=' '
for reg in `cat registro` line
do
    echo ${reg}
done

But the result gives me the first string of text before space:

102436350

This file is a big one but in each line I have many white spaces.

Don't use `cat`, don't use a `for` loop; see [Bash FAQ 001](http://mywiki.wooledge.org/BashFAQ/001). – chepner Jun 08 '17 at 19:52

@CharlesDuffy (@chepner): Is there a canonical SO Q&A for this? Should we find one? – Jonathan Leffler Jun 08 '17 at 20:27
@JonathanLeffler The dup here is listed on the `bash` tag info page, but that page is getting a bit difficult to use. – chepner Jun 08 '17 at 20:33
Thanks a lot all of you for this help. – Matias Araya Jun 08 '17 at 22:10
@chepner: Thanks for the pointer — I guess that shows how often I look at the Bash tag wiki. Yes, it is a bit large and verging on unwieldy. The information is there, if only you can find it. – Jonathan Leffler Jun 08 '17 at 22:41
