How to Get Printed Command Information in Shell Script

Question

I would like to issue a command in a shell script.

This command will have a return code, 0 or non-0, if success or not.

If successful, he will print something.

Now I need to print the material in a shell script. How can i do this?

I know that I can redirect the file and then read the file. Is there a way to redirect it to a variable directly?

Thanks so much for your info.

Answer 1

You can use the operator $(...)to capture the output of a command as a string. You may also have seen the old backtick syntax `...`that does the same.

output=$(command)
output=`command`

echo "$output"
