uux - UNIX-to-UNIX system command execution

_u_u_x will gather zero or more files from various systems, execute a
command on a specified system and then send standard output to a file on
a specified system.
NOTE: For security reasons, most installations limit the list of
commands executable on behalf of an incoming request from _u_u_x, permitting
only the receipt of mail (see _m_a_i_l(1)). (Remote execution permissions
are defined in ////eeeettttcccc////uuuuuuuuccccpppp////PPPPeeeerrrrmmmmiiiissssssssiiiioooonnnnssss.)
The _c_o_m_m_a_n_d-_s_t_r_i_n_g is made up of one or more arguments that look like a
shell command line, except that the command and file names may be
prefixed by _s_y_s_t_e_m-_n_a_m_e!!!!. A null _s_y_s_t_e_m-_n_a_m_e is interpreted as the local
system.
File names may be one of
(1) a full path name;
(2) a path name preceded by ~~~~_x_x_x where _x_x_x is a login name on the
specified system and is replaced by that user's login
directory;
(3) anything else is prefixed by the current directory.
As an example, the command
uux "!diff usg!/usr/dan/file1 pwba!/a4/dan/file2 > !~/dan/file.diff"
will get the _f_i_l_e_1 and _f_i_l_e_2 files from the ``usg'' and ``pwba''
machines, execute a _d_i_f_f(1) command and put the results in _f_i_l_e._d_i_f_f in
the local PUBDIR/dan/ directory.
Any special shell characters such as <<<<>>>>;;;;|||| should be quoted either by
quoting the entire _c_o_m_m_a_n_d-_s_t_r_i_n_g, or quoting the special characters as
individual arguments.
_u_u_x will attempt to get all files to the execution system. For files
that are output files, the file name must be escaped using parentheses.
For example, the command
uux a!cut -f1 b!/usr/file \(c!/usr/file\)
gets /usr/file from system "b" and sends it to system "a", performs a _c_u_t
command on that file and sends the result of the _c_u_t command to system
"c".

_u_u_x will notify you if the requested command on the remote system was
disallowed. This notification can be turned off by the ----nnnn option. The
response comes by remote mail from the remote machine.
The following _o_p_t_i_o_n_s are interpreted by _u_u_x:
---- The standard input to _u_u_x is made the standard input to the
_c_o_m_m_a_n_d-_s_t_r_i_n_g.
----aaaa_n_a_m_e Use _n_a_m_e as the user identification replacing the initiator
user-id. (Notification will be returned to the user.)
----bbbb Return whatever standard input was provided to the _u_u_x command
if the exit status is non-zero.
----cccc Do not copy local file to the spool directory for transfer to
the remote machine (default).
----CCCC Force the copy of local files to the spool directory for
transfer.
----gggg_g_r_a_d_e _G_r_a_d_e is a single letter/number; lower ASCII sequence
characters will cause the job to be transmitted earlier during
a particular conversation.
----jjjj Output the jobid ASCII string on the standard output which is
the job identification. This job identification can be used by
_u_u_s_t_a_t to obtain the status or terminate a job.
----nnnn Do not notify the user if the command fails.
----pppp Same as -: The standard input to _u_u_x is made the standard
input to the _c_o_m_m_a_n_d-_s_t_r_i_n_g.
----rrrr Do not start the file transfer, just queue the job.
----ssss_f_i_l_e Report status of the transfer in _f_i_l_e.
----xxxx_d_e_b_u_g__l_e_v_e_l
Produce debugging output on the standard output. The
_d_e_b_u_g__l_e_v_e_l is a number between 0 and 9; higher numbers give
more detailed information.
----zzzz Send success notification to the user.

Only the first command of a shell pipeline may have a _s_y_s_t_e_m-_n_a_m_e!!!!. All
other commands are executed on the system of the first command.
The use of the shell metacharacter **** will probably not do what you want
it to do. The shell tokens <<<<<<<< and >>>>>>>> are not implemented.
The execution of commands on remote systems takes place in an execution
directory known to the _u_u_c_p system. All files required for the execution
will be put into this directory unless they already reside on that
machine. Therefore, the simple file name (without path or machine
reference) must be unique within the _u_u_x request. The following command
will NOT work:
uux "a!diff b!/usr/dan/xyz c!/usr/dan/xyz > !xyz.diff"
but the command
uux "a!diff a!/usr/dan/xyz c!/usr/dan/xyz > !xyz.diff"
will work. (If _d_i_f_f is a permitted command.)
BBBBUUUUGGGGSSSS
Protected files and files that are in protected directories that are
owned by the requestor can be sent in commands using _u_u_x. However, if
the requestor is root, and the directory is not searchable by "other",
the request will fail.
