For a text file with this formatted entry:

William ted Thu 6/12 9:49 fred ralph
bill ted Thu 6/11 17:00 fred ralph

Using 'grep' and 'sort':

grep '6/11' file.txt | sort

...displays...

Michael thanks,

but my problem lies elsewhere,
I has two time stamps and would like to know, like many time past between them.

Hi,

This sounds like a tricky task to me!

Do you need to find the difference between them in hours, or whole days?

For days you will need to search the forum for A. Clay Stephenson's caljd.sh script. You will need to use sed or awk to extract the date as 6/12 and then use the appropriate options to caljd to output the Julian date. You can then subtract one Julian date from the other.

If you need to calculate the difference in hours or minutes then use the same approach, but you'll need to convert the 9:49 and 17:00 to minutes since midnight and perform a calculation on them.

regards,

Darren

Hi,

Or you can also compile this one using make :

hp:FORUMS> diffdate "6/12 9:49" "06/10 09:50"
Difference is 1 days 23 hours 59 minutes

You will perhaps need to better deal with controls and year ...

I believe,
thus month functioned also correctly must one in line 39 instead of (argv[1 ] ]) (argv[2 ]) write.

Still times thank you

Hi,

I wrote perhaps too fast ... Thank you for your correction. I'll keep it perhaps for another time in the forums.

Best regards.
