Linux Script to Solaris

Question

Hellooo! I have the following sentence, that works on Linux, but not in Solaris Version.

YEAR=2019
echo $(expr '(' $(date -d $YEAR/9/30 +%s) - $(date +%s) + 86399 ')' / 86400) " days until deadline" the error is due to the date

Error that appears:

command date: illegal option -- d usage: date [-u] mmddHHMM[[cc]yy][.SS] date [-u] [+format] date -a [-]sss[.fff]

Any ideas?

Thank you very much

The feature you are trying to use is included in GNU date (the default in Linux), but not in Solaris date.

You can install GNU date on Solaris from various third party repositories such as OpenCSW (free) or UNIXPackages ($).

Or it may be already installed as part of the OS under `/usr/sfw/bin` (Solaris 10) or `/usr/gnu/bin` (Solaris 11). – alanc Feb 16 '19 at 16:07
@alanc I'll go with that. Though it's been even longer since I used Solaris than it was for the other person. – Michael Hampton Feb 16 '19 at 17:25

It's been a little while since I've used Solaris. Last version I used was Solaris 10.
Answer: Solaris does not allow you to perform "date math." It does not like the -d option.

man date should show you that. There may be another option instead of -d, can't remember. Convert everything to seconds, maybe?

What, exactly, are you trying to accomplish?

Hello, the idea is to show how many days left to reach to a specific date. – pepeargento Feb 15 '19 at 18:22
So, you want to know something like: days=date(a) - date(b) You have to code that yourself. Are you a descent scripter? – Scottie H Feb 15 '19 at 19:18
descent... i dont know what you mean. I am starter, but i will put the best to script this... – pepeargento Feb 18 '19 at 12:31
Which version of Solaris are you running? – Scottie H Feb 18 '19 at 19:13
