What is wrong with this diff command?

jb_get · 09-29-2008, 06:27 AM

I am having trouble using the diff command correctly. I am using the following.

Code:

jb_get@jonesey:~/logs> diff  --unchanged-line-format= --new-line-format=  `find $myPath -type f -name "ip_summary-*" |sort -r |head -2` > /tmp/zGzb$$

but i keep getting this output

Code:

diff: missing operand after `--new-line-format='
diff: Try `diff --help' for more information.

Can someone tell me what I am doing wrong?

Thank you.

Moin,

are you sure, that your find/sort/head pipe returns 2 pathnames? I get the error message if no files are found.

I found where my problem was. When i searched for my files that were being created I was searching for "ip_summary-*" when in fact it should have been "ip_summary_*"...silly me

Thanks for the help
