Hello,
I've got a problem with SED. It's my intention to shorten a file path (removing the file name) with the help of SED. Something like:
tmp\folder1\folder2\blah.txt has to be transformed to
tmp\folder1\folder2\.
I suppose, it's on the tip of my tongue. Perhaps it's close to:

how do I alias the following command:

The alias command needs single quotes and so does the above command, so this does not work:

My problem is how do I get a listing of only directories?

pvm_reg_hoster
REG_HOSTER(3PVM) PVM Version 3.4 REG_HOSTER(3PVM)
NAME
pvm_reg_hoster - Register task as PVM slave starter.
SYNOPSIS
C #include <pvmsdpro.h>
int cc = pvm_reg_hoster()
Fortran Not Available
DESCRIPTION
Registers the calling task as a PVM slave pvmd starter. When the master pvmd receives a DM_ADD message, instead of starting the new slave
pvmd processes itself, it passes a message to the hoster, which does the dirty work and sends a message back to the pvmd.
Note: This function isn't for beginners. If you don't grok what it does, you probably don't need it. For a more complete explanation of
what's going on here, you should refer to the PVM source code and/or user guide section on implementation; this is just a man page. That
said...
When the master pvmd receives a DM_ADD message (request to add hosts to the virtual machine), it looks up the new host IP addresses, gets
parameters from the host file if it was started with one, and sets default parameters. It then either attempts to start the processes
(using rsh or rexec()) or, if a hoster has registered, sends it a SM_STHOST message.
The format of the SM_STHOST message is:
int nhosts // number of hosts
{
int tid // of host
string options // from hostfile so= field
string login // in form ``[username@]hostname.domain''
string command // to run on remote host
} [nhosts]
The hoster should attempt to run each command on each host and record the result. A command usually looks like:
$PVM_ROOT/lib/pvmd -s -d8 -nhonk 1 80a9ca95:0f5a 4096 3 80a95c43:0000
and a reply from a slave pvmd like:
ddpro<2312> arch<ALPHA> ip<80a95c43:0b3f> mtu<4096>
When finished, the hoster should send a SM_STHOSTACK message back to the address of the sender (the master pvmd). The format of the reply
message is:
{
int tid // of host, must match request
string status // result line from slave or error code
} [] // implied count
The TIDs in the reply must match those in the request. They may be in a different order, however.
The result string should contain the entire reply (a single line) from each new slave pvmd, or an error code if something went wrong.
Legal error codes are the literal names of the pvm_errno codes, for example ``PvmCantStart''. The default PVM hoster can return PvmDSysErr
or PvmCantStart, and the slave pvmd itself can return PvmDupHost.
The hoster must use pvm_setmwid() to set the wait ID in the reply message to the same value as in the request. The wait ID in the request
is obtained by calling pvm_getmwid().
The hoster task must use pvm_setopt(PvmResvTids, 1) to allow sending reserved messages. Messages should be packed using encoding Pvm-
DataDefault to ensure they can be unpacked anywhere in the system.
pvm_reg_hoster() returns PvmOk when successful.
