Sed - search and replace help.
Hi everyone,

basically I am been cleaning data by using simple sed commands

So what i have below has been working for me.
Code:
sed 's/="//g' trade.csv > tradeb.csv
sed 's/"//g' 	tradeb.csv > trade2.csv


but now i don't want to remove all the quotes just the ones if i encounter this data.

before:

... ,="123456780123456780","M", ....

after:

... ,123456780123456780,"M", ....

Is there an easy way to do this, like just a line of SED command?

Code:
sed 's/="\([^"]*\)"/\1/g'
