Each entry in a crontab file consists of six fields, specifying in the following order: minute, hour, day, month, weekday, and command1. Any of these fields can be set to an asterisk (*), which stands for "first through last." So, for example, to run a job every hour, put * in the hour field1. Each entry in a crontab file must end with a newline character (\n), which indicates the end of a line2. A newline character is created by pressing the Enter key on the keyboard. The other options are not valid characters for ending a crontab entry. A tab or a space is used toseparate each field, and a backslash is used to escape special characters or continue a long command to the next line2. References:

The locale is a set of environmental variables that defines the language, country, and character encoding settings for the applications and shell session on a Linux system. The locale affects things such as the time/date format, the first day of the week, numbers, currency and many other values formatted in accordance with the language or region/country you set on a Linux system1. The currency sign (¤) is a character used to denote an unspecified currency2. To display the correct currency symbol for a specific region, the locale must be set accordingly. For example, to display the euro symbol (€) for France, the locale can be set to fr_FR.UTF-81. Setting the timezone correctly, editing /etc/currency, or reinstalling the French language pack will not affect the currency symbol displayed in the spreadsheets.
