Many system administrators may wish to make use of the logging facilities of EMBOSS. Setting the variable
emboss_logfilein
emboss.defaultor
.embossrcallows the system to keep a log of which programs are used when and by whom.
set emboss_logfile /site/log/emboss.log
The log file structure is very simple. Three tab separated fields are stored, program name, user name, and the date and time.

The file defined in emboss_logfile should be world writable. The following command ensures logging can occur.
chmod +w /site/log/emboss.log
All settings can be overridden in a users
.embossrcfiles by redefining the relevant variables. So to prevent our system usage being logged we can redefine emboss_logfile by putting the following entry in our
.embossrcfile.
set emboss_logfile /dev/null
This behaviour may change in the future to prevent users redefining some system settings.
