TCSH script - add subfiles to a list

I'm working on an assignment, and I'm stuck on one point.  I'm trying to return the sum of the size of all files in a directory (including sub directories).  The du command is not allowed.

Consider the following directory structure:
testdir/
testdir/file1.txt
testdir/file2.txt
testdir/testsub/
testdir/testsub/file3.txt
testdir/testsub/file4.txt

My specific question is, how do I add the entire tree to a list in my script such that I can work with them the get the size.  I can get the size once there.

So far I have the following:

#!/bin/tcsh
...

  echo "Enter Directory Name:"
  set mydir = $<

  echo "Calculating the total of the size of all files in the directory tree"
  echo ""

  set mysum = 0        #variable to hold sum

  set filelist = $mydir
  set mycursize = 0    #variable to hold current filesize
  echo $filelist


  foreach x ($filelist)
    @ mycursize = `stat -c%s $x`    #finds current filesize
    echo "size of $x is $mycursize"
    @ mysum = $mysum + $mycursize    #accumulator
  end
 
  echo "The sum of the size of all files in this directory is: $mysum"
...

Open in new window


When I search testdir I currently get the size of only that directory, of course.
I've tried setting filelist = `ls -R $mydir`which does add all the subfiles, but when I run my script is says "No such file or directory" for every item in the list.

If you are allowed to use the find command that would do it.

find $mydir -type f

This would find only, not directories or other types.

To get in a list you can do like
set fls = ( `find files -type f` )

Whether you do stat on each item in the list or ls -l, it is up to you.

Do you need to recursively go through every directory in the file?
$x is a name, you need to use "$mydir/$x" which will include the explicit path/filename.
You can use ( test -f "$mydir/$x" ) regular file or use -d to test whether the item in the list is a directory.
