Perl modules. A few optional modules are displayed that are not yet<br />

available. You can subsequently install <strong>the</strong>m according to <strong>the</strong> methods<br />

described in Appendix A. The entry “user” shows <strong>the</strong> user name<br />

under which <strong>the</strong> scripts are executed. In addition, you will probably<br />

also see a warning regarding <strong>the</strong> RCS.<br />

10.4.1<br />

Changing RCS Owners<br />

For <strong>the</strong> RCS, <strong>the</strong> system must have access to <strong>the</strong> key to <strong>the</strong> RCS<br />

files. If this is not <strong>the</strong> case, modifications cannot be made. Files are<br />

issued with “nobody” as <strong>the</strong> default owner. If your system does use<br />

any o<strong>the</strong>r name (and that is most likely <strong>the</strong> case), you will have to<br />

change <strong>the</strong> owner. For this procedure, you will find a link to an<br />

automatic script on <strong>the</strong> page; however, at <strong>the</strong> time of this printing, it<br />

seems to still be in a very experimental stage. Thus, we have included<br />

a small script with which you can make <strong>the</strong> changes. To do<br />

this, change to <strong>the</strong> directory twiki/data and enter <strong>the</strong> following<br />

command:<br />

sh unlockrcs.sh username<br />

You can find your user name on <strong>the</strong> Testenv page under “user.”<br />

Caution: Do not confuse <strong>the</strong> user entry with <strong>the</strong> log name, located<br />

fur<strong>the</strong>r up.<br />

The script creates a backup file called old-data.tar.gz. If something<br />

has gone wrong, you can revert to <strong>the</strong> former state by copying <strong>the</strong><br />

backup file back over. This is done using<br />

tar xzvf old-data.tar.gz<br />

O<strong>the</strong>rwise, you can delete <strong>the</strong> backup file with<br />

rm old-data.tar.gz<br />

If you open testenv again, you will still see a warning, but this time,<br />

you can happily ignore it.<br />
