I am assuming t hat you are logged in as root, since creating jails requires higher level privileges. You may want to use zabbix to control your jails.
Try some or all of the following commands to create a jail called TEST:
Hello there,
My mulithreaded application (which is too large to represent the source code here) is crashing after installing FreeBSD 7.1-RELEASE/amd64.
It worked properly on others machines (Dual Cores with 4GB of RAM - FreeBSD 6.2-RELEASE/i386).
The current machine has 2x Core 2 Duo... (1 Reply)
Hello! I know I must take the efforts of learning C..! I need to recompile a binary with the following at the beginning: test if a file exists, remove it and exit. All in "C". As simple as this in sh:
file=/tmp/filename
if ; then
rm -f $file
exit 0
fi
Thanks! (8 Replies)
Hello!
I have a question to native English-speaking people. In the popular program's "hello world" greeting, what meaning the "world" has: "all", "everybody", "people", "friends" or "whole world", "planet", "Earth", "Universe"?
In other words, to whom this greeting is addressed: to the... (14 Replies)

md
md(1) BSD General Commands Manual md(1)NAME
md -- process raw dependency files produced by cpp -MD
SYNOPSIS
md [-d] [-f] [-m makefile] [-u makefile] [-o outputfile] [-v] [-x] [-D c|d|m|o|t|D]
DESCRIPTION
The md command basically does two things:
Process the raw dependency files produced by the cpp -MD option. There is one line in the file for every #include encountered, but there are
repeats and patterns like .../dir1/../dir2 that appear which should reduce to .../dir2. md canonicalizes and flushes repeats from the depen-
dency list. It also sorts the file names and "fills" them to a 78 character line.
md also updates the makefile directly with the dependency information, so the .d file can be thrown away (see d option). This is done to
save space. md assumes that dependency information in the makefile is sorted by .o file name and it procedes to merge in (add/or replace [as
appropriate]) the new dependency lines that it has generated. For time efficiency, md assumes that any .d files it is given that were cre-
ated before the creation date of the "makefile" were processed already. It ignores them unless the force flag [f] is given.
FLAG SUMMARY -D c|D|d|m|o|t
Specify debugging option(s):
c show file contents
D show very low level debugging
d show new dependency crunching
m show generation of makefile
o show files being opened
t show time comparisons
-d Delete the .d file after it is processed
-f Force an update of the dependencies in the makefile, even if the makefile is more recent than the .n file. (This implies that md has
been run already.)
-m makefile
Specify the makefile to be upgraded. The defaults are makefile and then Makefile.
-o outputfile
Specify an output file (other than a makefile) for the dependencies.
-u makefile
Like -m, but the file will be created if necessary.
-v Set the verbose flag.
-x Expunge old dependency information from the makefile.

Old, possibly not used by anyone.
HISTORY
The md utility was written by Robert V. Baron at Carnegie-Mellon University.
