The perl example is a good one.

If you must do it in sed, this one is a few characters shorter than the previous example Smilie

Code:
echo sys,systematic,system | sed -e 's/^/,/' -e 's/$/,/' -e 's/,system,/,HI,/g' -e 's/^,//' -e 's/,$//'

You could also do it in awk:

Code:
echo sys,systematic,system | awk 'BEGIN {FS=OFS=","} {for (i=1;i<=NF;i++) if ($i=="system") $i="HI"; print}'
