delimiter - Reading null delimited strings through a Bash loop

Question

I want to iterate through a list of files without caring about what characters the filenames might contain, so I use a list delimited by null characters. The code will explain things better.

# Set IFS to the null character to hopefully change the for..in
# delimiter from the space character (sadly does not appear to work).
IFS=$''

# Get null delimited list of files
filelist="`find /some/path -type f -print0`"

# Iterate through list of files
for file in $filelist ; do
    # Arbitrary operations on $file here
done

The following code works when reading from a file, but I need to read from a variable containing text.

while read -d $'' line ; do
    # Code here
done < /path/to/inputfile

Answer 1

The preferred way to do this is using process substitution

while IFS= read -r -d $'' file; do
    # Arbitrary operations on "$file" here
done < <(find /some/path -type f -print0)

If you were hell-bent on parsing a bash variable in a similar manner, you can do so as long as the list is not NUL-terminated.

Here is an example of bash var holding a tab-delimited string

$ var=$(echo -ne "foobarbaz"); 
$ while IFS= read -r -d $'' line ; do 
    echo "#$line#"; 
  done <<<"$var"
#foo#
#bar#
#baz#
