Escaping double quote and comma in shell

the command below will give the volumes of my Amazon instance

aws ec2 describe-instances --region us-west-2 --instance i-cbd35513 | grep -e "VolumeId" | cut -d ":" -f 2

and the output of that command is: 

"vol-f6be8636",
"vol-69be86a9",

But, I want the output 

 vol-f6be8636
 vol-69be86a9

Can anyone please show me or give me an example of how to do it? I would really appreciate of your helps.

You can do this:

aws ec2 describe-instances --region us-west-2 --instance i-cbd35513 |
awk '/VolumeId/{gsub(/[",]+/, "", $2); print $2}'

There is no need to have grep and cut now since my suggested awk command will do all the 3 jobs.

One of the simplest ways is to use tr:

other-commands | tr -d '",'

Meaning, tr, delete, then the characters to delete, inside single quotes so the shell doesn't interpret them.
