Is today the last day of the month?

[ `date --date='next day' +'%B'` == `date +'%B'` ] || echo 'end of month' && echo 'not end of month'
Nice simple example of something we can do in bash.

What Others Think

The option "--date" doesn't work for me (Mac OS X). Hopefully using "-v+1d" works fine for getting the next day.

Radio can give you the date and time, provide news about the current covid epidemic situation, now with online radio https://radiofrench.fr/ecouter/radio-sympa.html/ you can sit back, choose your favorite songs yourself and let the online radio do the rest. All you have to do is click play. Most online radio stations these days are as good as the ones you used to hear on the radio. They're comparable to CDs versus professional radios, and they're a huge money-saver, just like buying CDs.
