Another way to speed up could be to do the moves in the background:

Probably the best way though would be to build randomly or serially selected lists of file names and feed them to mv operations to specific directories, while observing ARG_MAX
Hi,
I want to write a script that deletes all folders and keep the last 10 recent folders.
I know the following:
ls -ltr will sort the folders from old to recent.
ls -ltr | awk '{print $9}' will list the folder names (with a blank line at the beginning)

Hi, all:
I've got two folders, say, "folder1" and "folder2".
Under each, there are thousands of files.
It's quite obvious that there are some files missing in each. I just would like to find them. I believe this can be done by "diff" command.
However, if I change the above question a... (1 Reply)

lndir
LNDIR(1) General Commands Manual LNDIR(1)NAME
lndir - create a shadow directory of symbolic links to another directory tree
SYNOPSIS
lndir [ -silent ] [ -ignorelinks ] [ -withrevinfo ] fromdir [ todir ]
DESCRIPTION
The lndir program makes a shadow copy todir of a directory tree fromdir, except that the shadow is not populated with real files but
instead with symbolic links pointing at the real files in the fromdir directory tree. This is usually useful for maintaining source code
for different machine architectures. You create a shadow directory containing links to the real source, which you will have usually
mounted from a remote machine. You can build in the shadow tree, and the object files will be in the shadow directory, while the source
files in the shadow directory are just symlinks to the real files.
This scheme has the advantage that if you update the source, you need not propagate the change to the other architectures by hand, since
all source in all shadow directories are symlinks to the real thing: just cd to the shadow directory and recompile away.
The todir argument is optional and defaults to the current directory. The fromdir argument may be relative (e.g., ../src) and is relative
to todir (not the current directory).
Note that BitKeeper, CVS, CVS.adm, .git, .hg, RCS, SCCS, and .svn directories are shadowed only if the -withrevinfo flag is specified.
Files with names ending in ~ are never shadowed.
If you add files, simply run lndir again. New files will be silently added. Old files will be checked that they have the correct link.
Deleting files is a more painful problem; the symlinks will just point into never never land.
If a file in fromdir is a symbolic link, lndir will make the same link in todir rather than making a link back to the (symbolic link) entry
in fromdir. The -ignorelinks flag changes this behavior.
OPTIONS -silent
Normally lndir outputs the name of each subdirectory as it descends into it. The -silent option suppresses these status messages.
-ignorelinks
Causes the program to not treat symbolic links in fromdir specially. The link created in todir will point back to the corresponding
(symbolic link) file in fromdir. If the link is to a directory, this is almost certainly the wrong thing.
This option exists mostly to emulate the behavior the C version of lndir had in X11R6. Its use is not recommended.
-withrevinfo
Causes any source control manager subdirectories (those named BitKeeper, CVS, CVS.adm, .git, .hg, RCS, SCCS, or .svn) to be treated
as any other directory, rather than ignored.
DIAGNOSTICS
The program displays the name of each subdirectory it enters, followed by a colon. The -silent option suppresses these messages.
A warning message is displayed if the symbolic link cannot be created. The usual problem is that a regular file of the same name already
exists.
If the link already exists but doesn't point to the correct file, the program prints the link name and the location where it does point.
