You don't need to use $? when checking a command's return value. You can check the command directly.
Or even
If anything goes wrong, it will likely print an error to standard error. If you redirect standard error into a logfile yourself before you run it, all error messages will go into it.
Hello,
I want to import an Oracle database file on my fresh DB, bought before successfully with exp command.
But is it possible to import some tables from the dmp file, because they are too large and it's so long !?

So I'm currently developing an automated test system and I'm verifying my results by running a set of baselined data through and comparing the output (which is in a txt file) to a baseline results file. So of course I'm just using the diff command. Unfortunately each time I run the test there are 2... (3 Replies)

scp
SCP(1) BSD General Commands Manual SCP(1)NAME
scp -- secure copy (remote file copy program)
SYNOPSIS
scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 ...
[[user@]host2:]file2
DESCRIPTION
scp copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides the same secu-
rity as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication.
File names may contain a user and host specification to indicate that the file is to be copied to/from that host. Local file names can be
made explicit using absolute or relative pathnames to avoid scp treating file names containing ':' as host specifiers. Copies between two
remote hosts are also permitted.
The options are as follows:
-1 Forces scp to use protocol 1.
-2 Forces scp to use protocol 2.
-3 Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the
two remote hosts. Note that this option disables the progress meter.
-4 Forces scp to use IPv4 addresses only.
-6 Forces scp to use IPv6 addresses only.
-B Selects batch mode (prevents asking for passwords or passphrases).
-C Compression enable. Passes the -C flag to ssh(1) to enable compression.
-c cipher
Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).
-F ssh_config
Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).
-i identity_file
Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to
ssh(1).
-l limit
Limits the used bandwidth, specified in Kbit/s.
-o ssh_option
Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no
separate scp command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

-P port
Specifies the port to connect to on the remote host. Note that this option is written with a capital 'P', because -p is already
reserved for preserving the times and modes of the file in rcp(1).
-p Preserves modification times, access times, and modes from the original file.
-q Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1).
-r Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.
-S program
Name of program to use for the encrypted connection. The program must understand ssh(1) options.
-v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection,
authentication, and configuration problems.
EXIT STATUS
The scp utility exits 0 on success, and >0 if an error occurs.

scp is based on the rcp(1) program in BSD source code from the Regents of the University of California.
