~/.bashrc
Make custom settings in ~/.profile or ~/.bashrc. To ensure the correct process-
ing of these les, it is necessary to copy the basic settings from /etc/skel/
.profile or /etc/skel/.bashrc into the home directory of the user. It is rec-
ommended to copy the settings from /etc/skel after an update. Execute the following
shell commands to prevent the loss of personal adjustments:
mv ~/.bashrc ~/.bashrc.old
cp /etc/skel/.bashrc ~/.bashrc
mv ~/.profile ~/.profile.old
cp /etc/skel/.profile ~/.profile
Then copy personal adjustments back from the *.old les.
11.1.2 The cron Package
If you want to run commands regularly and automatically in the background at predened
times, cron is the tool to use. cron is driven by specially formatted time tables. Some
of them come with the system and users can write their own tables if needed.
The cron tables are located in /var/spool/cron/tabs. /etc/crontab serves
as a systemwide cron table. Enter the username to run the command directly after the
time table and before the command. In Example 11.1, “Entry in /etc/crontab” (page 194),
root is entered. Package-specic tables, located in /etc/cron.d, have the same
format. See the cron man page (man cron).
Example 11.1:
Entry in /etc/crontab
1-59/5 * * * * root test -x /usr/sbin/atrun && /usr/sbin/atrun
You cannot edit /etc/crontab by calling the command crontab -e. This le
must be loaded directly into an editor, then modied and saved.
