If you want to call dig TXT on each record of your file, you may want to use this command:

 cat 1.txt | xargs dig TXT

As stated in the xargs man:

xargs reads items from the standard input, delimited by blanks (which can be protected with double or single quotes or a backslash) or newlines, and executes the command.

Edit: I just saw that dig does have a -f option, so you can also use:

dig TXT -f 1.txt

The output of the two commands are the same.
