Problem with xargs and mv is mv expects the destination on the end. But xargs tacks new arguments onto the end: ls | xargs mv destination will run mv destination file1 file2 file3 file4 which will complain "file4 is not a directory". (Or, if file4 is a directory, will mysteriously vanish everything into it )
Fortunately mv has an option that lets you put the destination before: -t.
Code:
find | xargs mv -t destination
will make it run mv -t destination file1 file2 file3 file4, which is what you need.
find * is redundant, by the way. The way to avoid too many arguments is to not use too many arguments, so don't do globbing at all. Just find by itself will find all files and directories in ./, including ./. You can restrict that further by giving it a specific place to look inside: find ./dir or telling it what kinds of files to find: find -type f (f is files, d is dirs), or certain names: find -iname '*.zip' or telling it a minimum depth to start at: find -mindepth 1 (depth 0 includes ./, depth 1 only includes its contents, etc.) You can keep adding more options to narrow it down to what you need. See man find for full details.

shmx
shmx(8) System Manager's Manual shmx(8)NAME
shmx - shared memory exerciser
SYNOPSIS
/usr/field/shmx [-h] [-ofile] [-ttime] [-msize] [-ssegment] [-v]
OPTIONS
You can use the following options: Prints the help message for the shmx command. Uses the fork(2) system call instead of the vfork(2) call
to spawn shmxb. Saves diagnostic output in file. Specifies the run time in minutes. The default is to run until the process is killed.
Specifies the memory segment size in bytes to be tested by the processes. Must be greater than 0. The default is SHMMAX/SHMSEG. (SHMMAX
and SHMSEG are system parameters set in the </sys/include/sys/param.h> file.) Specifies the number of memory segments. The default and
maximum number is 3.
DESCRIPTION
The shmx memory exerciser spawns the background process shmxb, and these two processes exercise the shared memory segments. They alternate
writing and reading the other process' data in the segments.
You can specify the number of memory segments to test and the size of the segment to be tested by shmx and shmxb processes. The shmx exer-
ciser runs until the process is killed.
A log file for you to examine and then remove is created in the current working directory. If there are errors in the logfile, check the
syslog files where the driver and kernel error messages are saved. The shmx exerciser is automatically invoked when the memx exerciser is
started. You can also invoke shmx manually.
RESTRICTIONS
If you need to run a system exerciser over an NFS link or on a diskless system, there are some restrictions. For exercisers that need to
write into a file system, such as fsx(8), the target file system must be writable by root. Also the directory from which the exercisers
are executed must be writable by root because temporary files are written into the current directory. These latter restrictions are some-
times difficult to overcome because often NFS file systems are mounted in a way that prevents root from writing into them. Some of the
restrictions may be overcome by copying the exerciser to another directory and then executing it.
EXAMPLES
The following example tests the default number of memory segments (3), each with the default segment size (SHMMAX/SHMSEG): %
/usr/field/shmx & The following example runs two memory segments of size 100,000 bytes for 180 minutes: % /usr/field/shmx -t180-m100000
-s2 &
