foreach question

OK, so I am extremely rusty and am just getting back to Unix after 9 years.

I'm stuck on something easy. I want to search line-by-line for a string in a file, and I want to do this to a series of files in a directory.

This works fine to do the search:

while read i; do grep $i file2; done <file1.txt

This also works fine to read a directory:

foreach file ('/bin/ls *.txt')
echo $file
end

but if I try and combine the two, no joy.

foreach file ('/bin/ls *.txt')
while read i; do grep $i file2; done <$file
end

Help please!

NAME
sagasu - GNOME tool to find strings in multiple files SYNOPSIS
sagasu [string [dir]] DESCRIPTION
sagasu is a GNOME tool to find strings in a set of files. The user specifies the search directory and the set of files to be searched. Double-clicking on a search result launches a user command that can for example load the file in an editor at the appropriate line. The search can recurse into subdirectories and can optionally ignore CVS directories. Two optional command-line arguments can be given: the first is the initial search string and the second is the directory whose files will be searched. If only one argument is given, it is taken as the search string. No search is actually started, but the appropriate fields are initialized. Any subsequent arguments are ignored. More documentation is available through the application's Help menu. OPTIONS

The files to be searches are still assumed to be in Latin-1, not in UTF-8. The same goes for the command-line arguments and the terminal to which Sagasu is connected, if applicable. HISTORY
Sagasu is a Japanese word that means "to search." June 19th, 2010 sagasu(1)
