Full Discussion: Print pipe separated list as line by line in Korn Shell

Put it in quotes.

Code:
STR="a|b|c|d|e"

Otherwise, it will assume they're pipes between commands.

To print them one per line:

Code:
STR="a|b|c|d|e"
OLDIFS="$IFS"
IFS="|"
printf "%s\n" $STR
IFS="$OLDIFS"

Changing the special IFS variable to "|" makes unquoted strings split on |, so $STR becomes a b c d e which, fed into printf "%s\n", prints each string on its own line.

Then you set IFS back to normal because you probably don't want it as | all the time.
