When running as user1 in the same directory (/home/user1/WWW)
[user1@server1 WWW (master)]# touch c
Creates the file c inside the directory.
[root@server1 WWW (master) ACCEPTATIE SERVER]# su - user1 -c "touch c"
gives the error
touch: cannot touch `c': Permission denied
Why can this be?
sudo group su

@Kusalananda yes the directory is owned byuser1:apache. I would suspect the first case would also fail when that was not true.

If your remove the-from the command and dosu user1 -c ...? With-you do a full login, and may end up in another directory than the directory you're currently in.

@steeldriver That's what I thought. But why woulduser1not be able to touchcin their home directory. Is there already a file owned by another user there?

@steeldriver that is the correct identification of my problem and is solved now. So conclusion for everyone coming here via google:su - user1 -cchanged the current working directory!

When you do su - username you perform a full login as that user, meaning that you are transferred to the user's home directory. When executing touch c in this way, you therefore try to run that command in the user's home directory.
Instead, drop the - from the command line:
su user1 -c "touch c"
This would execute touch c as user1 in the current directory.
Speculation:
The original su - command failed because there is already a file called c in user1's home directory owned by another user.
