join multiples seds
Hi
I have this string with 3 seds..

cat /tmp/roletmp|sed "s/$role2del//" | sed "s/,,/,/" |sed "s/^,//" |sed 's/,$//'

How can I join these 3 seds in one?

regards
Israel.

cat is also unnecessary:
Code:
sed -e "s/$role2del//" -e "s/,,/,/" -e "s/^,//" -e 's/,$//' /tmp/roletmp

Code:
sed "s/$role2del//;s/,,/,/;s/^,//;s/,$//" /tmp/roletmp

may also work.
