Executing nested loops+foreach

It's been a while since I used csh formatting and I am having a little bit of trouble with a few things. Things seem so much easier to execute in Matlab, however I need to do this on the terminal because of the programs I am trying to interact with.

So here's what I want to do: I have a file del.txt that is structured like this
Code:
1
2
3
4

etc. So each value is in it's own row and there's one column for all the data. I have a bunch of other files that are within my directory. I want to match up say value 1 (which in this case is 1) with file 1 and value 2 with file 2, etc and so on and so forth. So here's what I did...

Code:
#!/bin/csh
foreach a (`cat del.txt`)
  foreach sta(`ls *.HHZ`)
    echo a is $a
    echo $sta


    cat <<END>>macro.m
r $a
r $sta
END
    sac macro.m
    rm macro.m

  end
end

I added the extra end and now it loops through all of the values in del.txt and each file and then moves on to the next file within my directory and loops through all of the values. I'm having trouble figuring out the format that this should be in to match up the correct values. I'm not doing much within the script yet until I can get them to match up. Please help Smilie Can someone tell me what I'm doing wrong?

Cheers,

K

RDUP-UP(1)							       rdup								RDUP-UP(1)

NAME
rdup-up - update a directory tree with a rdup archive SYNOPSIS
rdup-up [OPTION]... DIRECTORY DESCRIPTION
With rdup-up you can update an (possibly) existing directory structure with a rdup archive. The rdup archive has to be given to rdup-up's standard input. Username and uids rdup outputs both the username and uid, the receiving system (which may be a totally different system) checks if the username and uid match. If the username and uid don't match the (numeric) uid is used on the file. The same holds true for the groupname and gid. OPTIONS
-n Do a dry-run and do not create anything on disk. -t Create DIRECTORY (ala mkdir -p) if it does not exist. -s N Strip N path components from a pathname. If the resulting pathname is empty after this operation it is skipped. Be careful however with the following structure: /foo /foo/bar /foo/bar/bla.txt /foo/blork/bla.txt With rdup-up -s2 this will leave: <empty> <empty> /bla.txt /bla.txt And the last 'bla.txt' will overwrite the previous one, this will happen without warnings. -r PATH This option is related to the -s option, but works different. The string PATH is removed from (the beginning of) each pathname. With -r /home/backup the pathname /home/backup/bin/mycmd becomes /bin/mycmd. The same could be done with -s 2, but then you need to count the slashes. Note -s is always performed before -r. -v Be more verbose and echo the processed files to standard output. -vv Be even more verbose and echo processed file and the uid and gid information to standard output. -T Show a table of contents of the rdup stream received (ala tar -tf -). With -T the directory argument is optional. -T unsets any verbose (-v) options. -h A short help message. -V Show the version. EXIT CODE
rdup-up return a zero exit code on success, otherwise 1 is returned. AUTHOR
