Indeed, there are many easter eggs inside your Terminal, but I believe these Terminal command lines will make you smile as it’s really fun to play around with. And for some, I am sure you’ve never seen them before.
cat /usr/share/misc/birthtoken | grep [month]
This Terminal command line will show you what is the birth flower and birth stone for the given birth month, instantly.
$cat /usr/share/misc/birthtoken | grep Jan January:Garnet:Carnation
Meaning of Flowers
cat /usr/share/misc/flowers | grep -i [flower-name]
Do you know that Camelia means reflected loveliness? Terminal knows it.
$cat /usr/share/misc/flowers | grep -i Clover Clover:Be mine.
Milestones in Music
cat /usr/share/calendar/calendar.music | grep [month/date]
Show you the date of birth of milestones in music related to the given month and date parameter.
$cat /usr/share/calendar/calendar.music | grep 01/10 01/10 Blues guitarist Howlin' Wolf dies in Chicago, 1976 01/10 Jim Croce is born in Philadelphia, 1943 01/10 Pat Benatar is born in Long Island, 1952 01/10 Rod Stewart is born in Glasgow, Scotland, 1945
cat /usr/share/dict/propernames | grep [portion-of-name]
This command line, if executed, will return you completed names from the give portion of name. Whether it’s proper or not, I doubt.
$cat /usr/share/dict/propernames | grep Te Ted Teresa Teri Teriann Terrance Terrence Terri Terry Teruyuki
cat /usr/share/calendar/calendar.birthday | grep [month/date] cat /usr/share/calendar/calendar.birthday | grep [name]
This particular Terminal command line will show you the birthdays of some famous people. Not so breaking though, I can’t even find Steve Jobs and Bill Gates birthdays inside.
$cat /usr/share/calendar/calendar.birthday | grep 09/16 09/16 Allen Funt born in Brooklyn, NY, 1914 $cat /usr/share/calendar/calendar.birthday | grep Steve 07/25 Steve Goodman is born in Chicago, 1948 11/13 Robert Louis Stevenson born, 1850
Thanks to reader James Hindle for pointing out that we can see today’s music, history, computer and birthday everytime we open up our Terminal, here is how to do it:
- Open Terminal and type vim ~/.bash_profile
- Press character i to go to Insert Mode
Insert the Terminal commands
today=`date "+%m/%d"` grep $today /usr/share/calendar/calendar.music grep $today /usr/share/calendar/calendar.history grep $today /usr/share/calendar/calendar.computer grep $today /usr/share/calendar/calendar.birthday
- Quit Insert Mode by pressing Escape key
- Type :wq to save the changes to the file and exit vim mode
- Relaunch your Terminal and now you should be able to see the changes
