Hi All,

I need replace a substring in shell script. The value of newString will be passed in as input argument. However the following script won't take the value of newString. Any suggestion?

Thanks,

Mike


newString=$1
oldSentence="This is an old way!"

echo $oldSentence | sed -e 's/old/$(newString)/g'

Try:

It works with double quotes! Thanks!

How do I replace "\" with "/" using sed?

Eg. oldstring="\asd\aaa\a.txt"

I want modify it to "/asd/aaa/a.txt"

echo oldstring | sed -e "s/\\/\//g" > newstring


Thanks!

You can use any character in the substitute expression so:

Not using "/" as the delimiter, makes replacing "/" in the text much easier.
