Full Discussion: Problem iterating through PATH entries with spaces

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.

latd.conf

LATD.CONF(5)							File Formats Manual						      LATD.CONF(5)

NAME

       latd.conf - LAT configuration file

SYNOPSIS

       /etc/latd.conf

DESCRIPTION

       /etc/latd.conf is a shell script (run by /bin/sh) that is run when latd is started up using the latcp -s command.
       It contains commands used to customise lat for your site and usually consists of a list of latcp commands.
       latd.conf is run with a minimal PATH and a minimal environment. The variable $LATCP points to the latcp binary used to invoke the script.

   EXAMPLE
	  # /etc/latd.conf
	  # This is a sample configuration file for latd
	  # it is run as s shell script from latcp -s with a minimal
	  # environment and PATH. latcp should be invoked using the
	  # environment variable $LATCP.
	  #
	  # You can fiddle with all the latd parameters you like in here,
	  # the first service announcement will not be made until this
	  # script completes.
	  #

	  # Set the multicast timeout to 30 seconds
	  $LATCP -m 30

	  # Add another login service
	  $LATCP -A -a ZAPHOD -r 100

	  # Add a queued reverse LAT service to a printer on a DECserver
	  $LATCP -A -p /dev/lat/printer -Hdecserver -Vdecserver -Q

	  # Only advertise our service in groups 1-10 and 200
	  $LATCP -G 1-10,200

	  exit
