Hi,

Try,

# find . -type f -exec ls {} \; | awk -F/ '{ print $2 }'

# find . -type f | xargs ls | awk -F/ '{ print $2}'

Try,

#find . -type f -exec ls {} \; | cut -c 3-

Best Luck.

Robert-Jan: ... awk -F/

It is probably safer to remove the "./" then use awk -F/:
$ find . -type f -exec ll -t + | sed 's:\./::'

Especially if find goes into subdirectories.

For example:
$ find . -type f -exec ls -lt {} \;
-rw-r--r-- 1 user group 0 Dec 14 11:46 ./testdir/test4.txt
-rw-r--r-- 1 user group 0 Dec 14 11:46 ./test1.txt
-rw-r--r-- 1 user group 0 Dec 14 11:46 ./test2.txt
-rw-r--r-- 1 user group 0 Dec 14 11:46 ./test3.txt

$ find . -type f -exec ls -lt {} \; | sed -e 's! ./! !'
-rw-r--r-- 1 user group 0 Dec 14 11:46 testdir/test4.txt
-rw-r--r-- 1 user group 0 Dec 14 11:46 test1.txt
-rw-r--r-- 1 user group 0 Dec 14 11:46 test2.txt
-rw-r--r-- 1 user group 0 Dec 14 11:46 test3.txt

Note that "-exec {} \;" syntax is very slow if there are lots of files, because it forks a new process for each file. As the ls command gets only one file to list at a time, the -t option (sort by time) will not be effective: the listing will be in the order determined by the find command.

The "-exec \+" syntax will be much more efficient, as each ls command will get as many files to list as possible (the limitation is the maximum length of a command line). If you use the -t option with the ls command and the list of files fits on a single command line, your list is guaranteed to be correctly ordered by time; but if find needs to execute multiple "ls -lt" commands, the sorting order of the entire list cannot be guaranteed.

$ find . -type f -exec ls -lt \+ | sed -e 's! ./! !'

My sed will do that. But as MK says, it may not be sorted the way you want.

Actually MK forgot to quote the ".". But he did guard for embedded ".". by using a space, so:
... | sed 's: \./: :'

How about the output of pwd(1) to find(1) instead of using "." in the path-list?

# find `pwd` -type f -exec ll -lt {} \;

>Sandman: How about the output of pwd(1)

Using $PWD in find will give absolute paths for everything.
$ find $PWD -type f -exec ll +

Hi,
why not only:
ls -lt|grep -v ^d

You will have a list of file in cronological order in current directory but not directories

HTH,

I thought I mentioned why on reply with 11:12:26 GMT. Try this:
$ find . -type f -exec ll -t + | sed 's: \./: :'
