Hi all,
I wanted to find all the that have both the number 63 and the letter "n". If I execute the following two commands, I get slightly different results.



Why am I getting different results?
Why do I get the following message?

Thanks in advance!!

In the first case you're searching for files or directories that have 63 and n in their names.
In the second case you're searching for ones containing n in their names in those which have a 63.

You get these error messages because you don't have the permissions to enter those directories.
Put sudo before your command, or add 2> /dev/null to its end if you want to ignore them.

Thanks.
Shouldn't both search return the same?

The search in both cases is different, but the final result should be the list of those path that contain 63 and n

No?

1) find(1) searches at any level for any name containing 63 AND n.
2) find(1) searches for names containing a n at each level of the directories that have a 63 in theirs.

In the second case you have:
[(number of names matching 63) + (number of names matching n in directories matching 63)] unique result lines.

So, perhaps you got 34 directories which match 63 and contain a filename with a n?

What does the following return?
