Code:
string="200910/22-101010"
 
echo ${string%-*}|tr -d "/"
20091022

For completeness: -

Code:
new_variable=$(echo ${string%-*}|tr -d "/")
echo $new_variable                         
20091022

newvar=$(echo ${ds%-*}|tr -d '/')

sed:
Code:
newvar=$(echo $ds|sed 's|/||;s|-.*||')
-or-
newvar=$(echo $ds|sed 's|/\(..\).*|\1|')

awk:
Code:
newvar=$(echo $ds|awk -F '[/-]' '{print $1$2}')
