Combining linux shell sed command

Question

I had three sed commands which are

sed 's/"//g'
sed 's/  *//g'
echo $1 | sed 's/.*'$2':\([^,}]*\).*/\1/'

How can I combine the above three sed commands together?

could you provide a sample input along with expected output? — Avinash Raj, Dec 01 '14 at 08:35
Use `sed -e`: http://unix.stackexchange.com/questions/33157/what-is-the-purpose-of-e-in-sed-command — pogibas, Dec 01 '14 at 08:37
and that's what happens when you try to meld copy-pasted code snippets without knowing what the hell are you doing. — Karoly Horvath, Dec 01 '14 at 08:39

You can combine multiple commands using -e

For example :

sed -e 'command' -e 'command'

Hope this helps .

To join sed command, you can also use ; without the -e like this:

sed 'code;code;code' file

eks:

sed 's/"//g;s/  *//g' file
