And if you're interested in the dotfiles (the otherwise invisible ones) make it
ls -lart   (that sequence of letters is ez 2 rmmbr if u r l33t ;-)).

Bimal you may also take a look at find command with time
 parameter, see man find for more details.

 You mean -mtime, -atime and -ctime options?  But this will also not
 give latest `created' file.  Let's hear from Ankit if he found what he
 was looking for.

Hmm.
 % cd $dir
 % ls -last | head -n 3

Seems to work for me. If you want the output to be easier to
 parse, and to ignore . and .., use:
 % ls -t | head -n 1

I believe this will work, but only in current directory ( not recursively )

ls -l | grep -v '^total' | tr -s   ' ' | sort -t ' ' -k 6,7 | tail -1 |
cut -f 8 -d' '

Try this:

getLatestFile(){
if [ $# -eq 1 ]; then
  ls -tr $1 | tail -1
else
  echo usage: getLatestFile dir
fi
}

ex.
$ getLatestFile ~
$ getLatestFile .
$ getLatestFile /tmp

Well, you can't get the time of creation of a file, as that is
not stored. You can get various other times, such as the time
of modification, time of access (unless this has been turned off
at the filesystem level), and time of modification of file status.

 I believe this will work, but only in current directory ( not recursively )
 
 ls -l | grep -v '^total' | tr -s   ' ' | sort -t ' ' -k 6,7 | tail -1 |
 cut -f 8 -d' '

Eek, try,
 ls -lr | tail -1
for time of last access. See ls -t, and ls -c for other times.

Regards,
Gora

Gora Well, you can't get the time of creation of a file, as that is
Gora not stored. You can get various other times, such as the time
Gora of modification, time of access (unless this has been turned off
Gora at the filesystem level), and time of modification of file status.

@Ankit, Gora is right, file creation time is not stored.  What above
code gives you is the latest `modified' (not necessarily created)
file.

If you want the last file whose inode was modified (which is usually the 
same as the last file created):

ls -c | head -1

P.S. *nix has ``directories'', not ``folders'' ;)

Yet again, here is a Ruby one liner:

ruby -e 'puts Dir[./**/*].delete_if { |f| File.directory?(f) }.sort_by {
|f| File.mtime(f) } [ -1 ]'

Also that it works recursively.

inotify will throw events, one has to listen to it. I think OP just
wanted to get latest created file in a directory, not to listen for
files creation events.
