-mtime +1 is older than 48 hours (more than 1 day, so at least 2
days). It's -mtime +0 for more than 24 hours.

Use ! -name . -prune, or the GNU -maxdepth option.

Or use zsh:

ls -ld -- foo.*(m+0)

lists the at least 1 day old files.

~$ ls -l a
-rw-r--r-- 1 chazelas chazelas 642469 Dec 1 22:10 a
~$ date
Thu Dec 3 19:46:17 GMT 2009
~$ find a -mtime +1
~$ find a -mtime +0
a
~$ ls -ld a(m+0)
-rw-r--r-- 1 chazelas chazelas 642469 Dec 1 22:10 a
~$ ls -ld a(m+1)
zsh: no matches found: a(m+1)
~$ ls -ld a(mh+23)
-rw-r--r-- 1 chazelas chazelas 642469 Dec 1 22:10 a

(more than 23 hours, so at least 24)

Just as another option, you can create a file once a day using cron,
and then later list all files newer than that file. Heck, you can even
do a simple ls by time, and chop off all files

ls -t | sed -n '/MARKFILE/{d;q}'

RTFM!

Firstly, GNU find has -mindepth and -maxdepth, which are useful.
If you have GNU find, you can simply ``find . -maxdepth 1 ...''
and find won't recurse into subdirectories. Done!

If we restrict ourselves to POSIX find, what we can do is prevent find
from descending into directories by including the clause ``-type d
-prune'' disjunctively.

For instance:

# Not quite right!

# find objects of type f (regular files) and print them,
# or find directories and prune them from the search

find . -type f -print -o -type d -prune # <- wrong

Now the above won't do anything because find finds the . directory
first. It does what it's told and prunes it. Several
ways to fix that. Expand the files yourself. Now
find is not really finding anything any longer:

find .* * -type f -print -o -type d -prune

However, even though find is not doing the work of finding
anything, it's still applying the rules. We can add
the modification time criterion:

find .* * -type f -mtime +1 -print \
-o -type d -prune

Another way to get find to visit the . directory instead of pruning it
is to force a match for the name '.' on the left hand side of the -o.
The -o operator is a short-circuited or; if the left hand side matches,
the right side is not evaluated, and so the pruning side effect does not
take place.

# visit the current directory, but don't print it;
# and visit the files, printing those, but don't
# recurse into subdirectories.

find . \( -type f -print -o -name '.' \) -o -type d -prune

Now adding the modification time at least 24 hours ago test:

find . \( -type f -mtime +1 -print \
-o -name '.' \) \
-o -type d -prune

Maybe not now, but there was. The original Unix stored a creation
time in a file's inode.
