Some scripts may create multiple lines which are too long to be displayed on a single line. The widget will not wrap these. In order to wrap them you can use the fold command: | Some scripts may create multiple lines which are too long to be displayed on a single line. The widget will not wrap these.

- | command-that-produces-long-lines | fold -s -w | + | command-that-produces-long-lines | fold -s -w 80 |
The 80 in that instance is the maximum length of the line, which you can change. The -s option makes fold word wrap with spaces. More information is available from the [http://unixhelp.ed.ac.uk/CGI/man-cgi?fold fold man page]. | The 80 in that instance is the maximum length of the line, which you can change.

This third script combines the functionality for both of the above widgets from a single script, to be installed as e.g. /usr/local/bin/countdown, and moves the bus stop configuration from variables to flat files, arranged by placename. It also adds some command-line functionality (not yet widgetised), which enables you to configure a given placename from the 5-digit code of a single bus stop. | This third script combines the functionality for both of the above widgets from a single script, to be installed as e.g. /usr/local/bin/countdown, and moves the bus stop configuration from variables to flat files, arranged by placename.
