1. /opt/ibm/lotus(/opt/lotus) this string must ends with "lotus"
2./ibw/latest

For the first part use this:

Code:
"${str%${str#*lotus}}"

for the second this:

Code:
"${str#*lotus}"

Or with sed:

Code:
echo "/opt/ibm/lotus/ibw/latest" | sed 's!\(.*lotus\).*!\1!'

gives: /opt/ibm/lotus

Code:
echo "/opt/ibm/lotus/ibw/latest" | sed 's!.*lotus\(.*\)!\1!'

gives: /ibw/latest
