view $PATH (or any colon separated string) as a readable multiline output — tested on OSX bash

colon_to_multiline.sh

##### first attempt

# one-liner
echo $PATH | sed -e "s~:~\\`echo -e '\n\r'`~g"

# bash function
sep2ln()
{
   local INPUT=$1
   local SEPARATOR=$2
   echo "$INPUT" | sed -e "s~${SEPARATOR}~\\`echo -e '\n\r'`~g"
}

sep2ln $PATH :

# one-liner
echo $PATH | sed -e s~:~'\'$'\n'~g

# bash function
sep2ln()
{
   local INPUT=$1
   local SEPARATOR=$2
   echo "$INPUT" | sed -e "s~$SEPARATOR~"'\'$'\n'~g
}
