Problem iterating through PATH entries with spaces

I have a Bash script on Cygwin that tries to iterate through the directory entries in PATH. I need to convert the PATH value to a form that I can iterate through with "for var in $list; do".

For instance, an excerpt from my PATH value is this:

:/c/Program Files/Windows Imaging/:/c/Program Files/MySQL/MySQL Server 5.1/bin

I need to somehow coerce this into something I can iterate through, where each original PATH entry goes into a variable.

I tried replacing " " (space) with "\ " (escaped space). That seems correct, but I also have to replace ":" (colon) with " " (space). I also tried replacing ":" with "\n", but that doesn't seem to help. Inside the "for" loop, the value of "var" never includes the full directory name, it always breaks at spaces in the names.

Duh. Never mind. I discovered "IFS=$':'". Very simple.

$ echo ":/c/Program Files/Windows Imaging/:/c/Program Files/MySQL/MySQL Server 5.1/bin" | tr ":" "\n" | sed '/^$/d' | while read line; do
> echo "$line"
> done
/c/Program Files/Windows Imaging/
/c/Program Files/MySQL/MySQL Server 5.1/bin

Please let me know if this would have worked for you?

Make an array
declare -a arr
arr=$(echo $PATH | tr -s ':' ' )

echo $PATH | awk -F: '{ for (i=1; i<=NF; i++) {print $i}}' |
while read fname
# something

for i in $PATH
    echo $i
