this is what i've tried so far, but it won't populate log.txt. i've purposefully added a directory (scripts) that doesn't exist to force the ls command to fail.

Code:
ls -lR  > scripts/release_file.txt 2>&1 | tee -a log.txt

i suspect it's the first redirection that's causing the problem as the command usually works if i'm not outputting the ls results to another file.

You were close...
Code:
$ ls data notthere
ls: notthere: No such file or directory
data
$ ls data not_there 2>&1 >stdout | tee stderr
ls: not_there: No such file or directory
$ cat stdout
data
$ cat stderr
ls: not_there: No such file or directory
$
