I am very new to Linux/Unix. Kindly assist the following:
I wish to write a bash shell script called how_many_to_go that calculates and prints the number of days, hours, minutes and/or seconds until the end of the current month (based on the output of the date command).
Do not make any assumptions about what month it is - the script should run properly in any month.
Assume that it is not a leap year, so the number of days in any month is known (February has 28 days; April, June, September, and November have 30 days; All the rest have 31 days).
The output should read "There are d days, h hours, m minutes, and s seconds until the end of the month" except as modified by the command line arguments below.
The script should accept command line arguments as follows (assume that it's now 11:00:00 PM on January 30):
[list]
how_many_to_go - print the number of days, hours, minutes, and seconds until the end of the month (e.g. "There are 1 days, 1 hours, 0 minutes, and 0 seconds until the end of the month")
how_many_to_go h - print the number of hours, minutes, and seconds until the end of the month (e.g. "There are 25 hours, 0 minutes, and 0 seconds until the end of the month")
how_many_to_go m - print the number of minutes and seconds until the end of the month (e.g. "There are 1500 minutes and 0 seconds until the end of the month")
how_many_to_go s - print the number of seconds until the end of the month (e.g. "There are 90000 seconds until the end of the month")
