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.

BUGS
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."
