php - opening file with vim creates a new file although the file exists -

-

I am trying to read in the apache error log var / log . I have a error.log file, but when I sudo vim this is a new error.log file is created. I'm pretty sure there should be anything in it because I'm trying to debug 500 internal server errors.

Thank you for your help!

Was followed by sudo vim error.log .
