How to replace a variable content

josephwong · #1 (**permalink**) 06-23-2006

Hi,

variable1="This is a car"

Now I want to replace the content of variable1, "car" to "dog". Is there any simple command I can use.

Thanks.

Joseph

You don't say which shell you are using. This is bash...

Code:

variable1=${variable1/car/dog}

korn shell,

It seems it does not work.

Any suggestions? Thanks.

I am not aware of any shell-builtins' (except for the ones Ygor posted) which carries out string replacement.

Try sed

Code:

echo "$variable" | sed -e "s_car_dog_g"

awk can do it as well. Look into the gsub method.
