Any clues ???

Try adding '-type f'. The ls -l is acting on the current directory.
That's what I reckon anyway.

The output of the the "find" command includes both files and
directories. When you invoke "ls -l" with a directory name, it lists
the contents of the directory, not just the directory itself.
Try using "ls -ld" rather than "ls -l", or use "find ... -ls" if you
don't mind a somewhat different output format.

a) find . -mtime 0
If The results of the above command 'a' generates 5 rows
why is the result of the command
b) find . -mtime 0 - exec ls -l {} \;
generating more than 5 rows
c) find . -mtime 0 -exec rm {} \;
I expect the result of the command 'c' will delete only the rows found
by the first part of the command
find . -mtime 0
Any clues ????

Did you consider Kieth's and Tony's comments?
Or try their suggestions?
Let me ask you, both ./etc and ./etc/passwd are possible outputs
from your command if run from the root directory. Each are just
one "row" of the output from command a). Yet "ls -l ./etc/passwd"
(command b) only generates one row of output while "ls -l ./etc"
generates about 300. Why is this??
BECAUSE /etc IS A DIRECTORY!
Go back and consider the already provided answers.

Thanks to all your responses.....
I have now understood the issue
And I am totally clear......
Sorry guys, for being so dense.....I guess I have been working a lot
lately and not watching TV -
I guess I need some TV time too....This helps you know.
No, I am not joking....
When they built the pyramids - the suggestion to increase output was
let the workers who were working 7 days a week get a day off....It
sounded crazy but yes - The output increased when the workers got one
day off....

Because "ls -l ." generates more than one row.
