Shell Programming and Scripting

Hi all,

Anybody knows how to write a script to
open a file and store the weekday(mon-sun) on first line and current datetime on
the second line of the file.
If file doesn't exist, create a new one and store the weekday and current datetime.
If it already exists, open it and get both weekday and the datetime.
compare this date(got from file) with the current datetime.
Display only the difference.
Before closing the script put the weekday and the current date(i.e., whichever day and time the script is called) in the file on the 1st and 2nd line resp.

Please help with the code.

Thanks in advance

Do you have some code that you have written for the problem.
If you have please share with the others and if you have'nt I believe you should read the forum rules https://www.unix.com/showthread.php?threadid=2971

See Point 6

I must agree with encrypted - this could be interpreted as a homework problem due to the complex nature of the request and the lack of any kind of script that you've done to show that it's a problem that you've been working on yourself.

Please don't let this stop you posting in future, but be aware of the forum rules, and please do not post homework questions on these boards - if you are having problems your tutor will be happy to help.

In future (and of course, if this isn't homework), please post what you have done so far, and then people will be willing to help you with your problems, not do them for you.

Cheers
