Print line if contains word

Question

I am trying to make a batch file to execute a few things for me.
Now I do understand a few programming languages, but I haven\'t done much in batch file programming yet.

If you simply want to output the matching line with no logic checking, do

findstr /i "node" "%file1%"

If you want to execute some code if the line is found, use conditional execution.

findstr /i "node" "%file1%" && (

    rem File contained "node".  Do some stuff.

) || (

    rem File did not contain "node".  Do something else.

)

And if you want to use findstr to test for the existence of a string without actually dumping the result to the console, simply add >NUL either before or after the findstr command.

>NUL findstr /i "node" "%file1%" && (success) || fail
