Long http user name is not detected correctly

Description

When the http user username is longer than 7 characters, the ps axo user,comm command seen here will cut the username and $httpUser gets an incorrect value.

In my case the http user on the remote machine is "deployment" so the above command output is:

$ ps axo user,comm | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d ' ' -f1
deploym+

To fix this issue, either the width of user-column needs to be increased using user:width or move user to the last column of ps axo output. Similar issue can be found in Askubuntu. For example:

$ ps axo user:20,comm | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d ' ' -f1
deployment

Steps to reproduce
