how to replace " to ' using sed ?

qzhu

I need to replace all double quote , i.e. " with 2 single quotes ' '
Could any one tell me how to do this using sed?
sed 's/\"/\'\'/g' does not seem to be working, its a little bit tricky.

大螞蟻

sed 's/\"/\'/g'

都說(shuō)過(guò)不行了

樓主看清楚了

1. echo '""' |sed s/\"/\'\'/g

復(fù)制代碼

多謝，原來(lái)如此簡(jiǎn)單。 簡(jiǎn)單之后的道理呢，說(shuō)簡(jiǎn)單也簡(jiǎn)單，說(shuō)不簡(jiǎn)單也不簡(jiǎn)單。
