information for sc is not found

[fenglish]

Hi,

I found below sentences from an IR document,

To determine whether the SCI tools are installed on the IR system, at the Unix prompt, enter pkginfo sc

If the SCI tools are not installed on the IR, the system displays the following message:

UXkginfo: ERROR: information for sc was not found

​

In above sentence, can I use "is" at the position of "was"? and why?

Thanks.

Yes, but there will be a little difference between them.
