In your example, it appears that you have an extra <CR> and <LF> in the 3rd field that are before the end of field/line. Is that what you are trying to eliminate?

Perhaps this will get you thinking:
Code:
$ echo "jim|jones|hairy" | sed "s/$/|~/g" | awk '{FS=OFS="|"; $0=$0; gsub("\151","e",$3); print }'
jim|jones|haery|~

I added a delimiter | and ~ characters to end of each line; this may be needed so as only to change CR and LF within the 3rd field.
the \151 is the octal representation for i in hairy. Thus, find the codes for CR and LF and try the above for your example.
