Having given that caveat, the source command was present on all of the distributions this article was tested against Ubuntu, Debian, Manjaro, Arch, Fedora, CentOS, and OpenIndiana. The period command should always be present. But not all distributions provide the source command.
RASPBERRY PI GEDIT SOFTWARE
The OS comes with over 35,000 packages: precompiled software bundled in a nice format for easy installation on your Raspberry Pi. The source command is an alias for the period command and performs the same action. Raspberry Pi OS is a free operating system based on Debian, optimised for the Raspberry Pi hardware, and is the recommended operating system for normal use on a Raspberry Pi. Note that the line starts with a dot or period. To see these changes take effect, either log out and back in or issue this command. Of course, you’d substitute the command that launches the editor you wish to use for ‘gedit’. When the editor appears, add this entry to the file: We can set the default editor for crontab by adding a line to our. This command will read the 200MB file created in the first command dd iftest of/dev/null bs1048576. This command will write a 200MB file called test to the SD Card dd if/dev/zero oftest bs1048576 count200. WARNING: you must be careful using DD as incorrect options can erase your SD card. What About Distros That Don’t Provide select-editor? DD can also be used to test SD card speeds.
But what if you want to use an editor that isn’t in that menu? Or what if you’re working on an operating system that doesn’t provide the select-editor command? We can handle those scenarios as well. If you later change your mind, how do you pick another editor if you only get the menu the first time? That’s easy. The editor that you select from the menu is used every time you issue the crontab -e command. In this example, nano was chosen by pressing the 1 key. The editor you select is then used to open your cron table. Type crontab, a space, -e and press Enter. The very first time you issue the crontab command with the -e (edit) option in a Bash terminal, you’re asked to pick the editor you’d like to use.

Your cron table holds the list of any scheduled jobs you have set to occur at specified times. The crontab -e command will open an editor so that you can edit your cron table.
What we’re going to show you is how to change the default editor for crontab to something else, should you choose to. We’re not stoking that fire, nor advocating one editor over another. Yet the depth of feeling people associate with their personal preference editor has led to flame wars that have been burning since 1985.
