tar cv /dev/rmt/0 /etc

tar c /dev/rmt/0
There is much variation in the tar syntax and without knowing the Operating System and version it can be difficult to guess without access to the "man tar" documentation on the server.
Best guess. In order:
1) Should create "-c" an archive to tape device /dev/rmt/0 of the contents of the directory /etc , listing the files on the terminal "-v" as it goes.
The command line would be easier to follow as:
tar cvf /dev/rmt/0 /etc
2) Syntax error. Contains both "c" (Create new archive) and "x" (Extract) on the same line. Impossible request.
3) IMHO. Would appear to hang expecting you to provide the file list specification from the keyboard as you have not provided it as a parameter or via a pipeline.
Btw. Nowadays actually having a tape device called /dev/rmt/0 is unusual. Find out what your tape device is actually called.

FBB::lm(3bobcat) OFoldStream manipulator FBB::lm(3bobcat)
NAME
FBB::lm - Manipulator setting left margins of OFoldStream objects
SYNOPSIS
#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat
DESCRIPTION
The lm class implements a manipulator that can be inserted into OFoldStream objects to set the stream's left margin to a requested value.
Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of
tab-characters that will be used for the left margin.
The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a
line is still once an lm object and a flush manipulator are inserted into the stream then the new left margin will be effective at the next
word inserted into that line (cf., the example section below).
A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.
NAMESPACE
FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.
