I ve worked with many users who have had problems with a script they have coded and debugged for a significant amount of time, only to arrive at the conclusion that It works from the command line, but not from cron ! I have run into this problem from time to time myself, but knowing the issues tends to help you find the solution much more quickly. A script running from cron is not run in the same shell environment as a command typed at the prompt. When you log in to a machine and you are at the shell prompt, many variables need to be set to enable your interactive shell session. cron is not run from an interactive session, however. A cron job runs with only some of the shell environment variables that are set in an interactive shell session. The cron job has only a very rudimentary environment. Most problems with users cron scripts stem from the assumption that the code runs in an environment with the characteristics of an interactive session, rather than the cron environment. Here s an example to illustrate the difference. This is one of my user environments, which is displayed when I use the env command:

After you create a GtkNotebook, it is not very useful until you add tabs to it. To add a tab to the end or beginning of the list of tabs, you can use gtk_notebook_append_page() or gtk_notebook_prepend_page(), respectively. Each of these functions accepts GtkNotebook, a child widget, and a widget to display in the tab as shown below. gint gtk_notebook_append_page (GtkNotebook *notebook, GtkWidget *child, sGtkWidget *tab_label);

to do in Figure 6-33.

Tip The tab label does not have to be a GtkLabel widget. For example, you could use a GtkHBox widget

I then set up the following cron job to run temporarily for illustrative purposes:

doing in Figure 6-34.

that contains a label and a close button. This allows you to embed other useful widgets such as buttons and images into the tab label.

After the job ran and created the env.out file, I found the following lines in it:

OK. Now you will see that in your Objects and Timeline panel you no longer have a Canvas with three Ellipses in it but rather a Button control. Notice, though, how the text of the Button is black and not centered on the Button (see Figure 6-35). We can fix that by using a TextBlock which gives more control for positioning and color. Let s do that now:

Each notebook page can only display one child widget. However, each of the children can be another container, so each page can display many widgets. In fact, it is possible to use GtkNotebook as the child widget of another GtkNotebook tab.
