Top Forums Shell Programming and Scripting Changing date using bash script Post 303023061 by rbatte1 on Tuesday 11th of September 2018 08:08:32 AM

Welcome novilatte,

Sadly I don't know what you are trying to achieve as output here. Can you explain?

Is it homework perhaps? There is a special forum for this.

I could guess that you want a sequence of dates where the month and the day add one each iteration but I'm not sure why.

.... or is it that you want every combination of valid dates for these months. In this case, you are missing the 31st when that occurs and including the 30th February, and taking no account of a leap year.

Would the output from cal be useful?
Can you explain the purpose of this in context? There may be a better way.




Kind regards,
Robin
