Copy Files Telnet

8/8/2019 Copy Files Telnet

1/9

Hi,

You may try these commands to copy files from telnet to local pc:

# smbclient \\ipaddress\sharename -U sharename(Now,It will prompt for username and passwd)

# get filename(Not that particular file will be copied to your local drive)

Try the above ....

Rep:

You could pipe the file using tar & netcat. Using telnet, you

would tar the file, piping the output to netcat. On the receivingend, use netcat with the -l (listen) option and pipe the output to

tar to extract the file.

---

Using ssh, with PKA, you wouldn't have authentication getting inthe way and could do it directly:tar -C directory/ -cf - file(s) | ssh user@host tar -C dest_dir/

-xvf -

You could transport a directory hierarchy this way securely toanother computer over the internet using ssh & tar.

You might try it with telnet instead of ssh. I don't have a telnet

server on my network to test it.Last edited by jschiwal; 03-11-2009 at06:05 AM.

Why use the command-line?

"Under Linux there are GUIs (graphical user interfaces), where you can point and clickand drag, and hopefully get work done without first reading lots of documentation. The

traditional Unix environment is a CLI (command line interface), where you typecommands to tell the computer what to do. That is faster and more powerful, but requiresfinding out what the commands are."

-- from man intro(1)

There are many varieties of Linux, but almost all of them use similar commands that can

be entered from a command-line interface terminal.

3/9

There are also many graphical user interfaces (GUIs), but each of them works differently

and there is little standardization between them. Experienced users who work with many

different Linux distributions therefore find it easier to learn commands that can be used inall varieties of Ubuntu and, indeed, in other Linux distributions as well.

For the novice, commands-line interface commands can appear daunting:

sudo gobbledegook blah_blah -w -t -faWkward/ComBinationOf/mixedCase/underscores_strokes/and.dots

However, it is important to note that even experienced users often cut and paste

commands (from a guide or manual) into the command-line terminal; they do not

memorize them.

It is important, of course, to know how to use the command-line terminal - and anyonewho can manage typing, backspacing, and cutting and pasting can manage the command-

line terminal (it is not more difficult than that).

This page will outline a few crafty shortcuts which can make using a command-line

interface easier.

Using this page

All command names will be in bold.

Commands needing to be typed will be in "bold with quotes".

All of the commands on this page are to be issued from a command prompt in aterminal.

Note that the terminal is case sensitive. User, user, and USER are all differentto Linux.

Starting a Terminal

In Gnome (Ubuntu)

The terminal can be found at Applications menu -> Accessories -> Terminal.

In Xfce (Xubuntu)

The terminal can be found at Applications menu -> System -> Terminal.

In KDE (Kubuntu)

The terminal can be found at KMenu -> System -> Terminal Program (Konsole).

In LXDE (Lubuntu)


4/9

The terminal can be found at Menu -> Accessories -> LXTerminal.

Commands

sudo: Executing Commands with Elevated Privileges

Most of the following commands will need to be prefaced with the sudo

command. This elevates privileges to the root-user administrative leveltemporarily, which is necessary when working with directories or files not owned

by your user account. When using sudo you will be prompted for your password.

Only users with sudo (administrative) privileges will be able to use this command.(Please see RootSudo for more information on using sudo.)

File & Directory Commands

The tilde (~) symbol stands for your home directory. If you are user, then the tilde(~) stands for /home/user

pwd: The pwd command will allow you to know in which directory you're

located (pwd stands for "print working directory"). Example: "pwd" in theDesktop directory will show "~/Desktop". Note that the Gnome Terminal also

displays this information in the title bar of its window. A useful gnemonic is

"present working directory."

ls: The ls command will show you ('list') the files in your current directory. Usedwith certain options, you can see sizes of files, when files were made, and

permissions of files. Example: "ls ~" will show you the files that are in your

home directory.

cd: The cd command will allow you to change directories. When you open a

terminal you will be in your home directory. To move around the file system you

will use cd. Examples:o To navigate into the root directory, use "cd /"

o To navigate to your home directory, use "cd" or"cd ~"

o To navigate up one directory level, use "cd .."

o To navigate to the previous directory (or back), use "cd -"

o To navigate through multiple levels of directory at once, specify the full

directory path that you want to go to. For example, use, "cd /var/www" togo directly to the /www subdirectory of /var/. As another example, "cd~/Desktop" will move you to the Desktop subdirectory inside your home

directory.

cp: The cp command will make a copy of a file for you. Example: "cp file foo"will make a exact copy of "file" and name it "foo", but the file "file" will still be

there. If you are copying a directory, you must use "cp -r directory foo" (copy

recursively). (To understand what "recursively" means, think of it this way: tocopy the directory and all its files and subdirectories and all their files and

subdirectories of the subdirectories and all their files, and on and on,

"recursively")
https://help.ubuntu.com/community/RootSudohttps://help.ubuntu.com/community/RootSudo


5/9

mv: The mv command will move a file to a different location or will rename a

file. Examples are as follows: "mv file foo" will rename the file "file" to "foo".

"mv foo ~/Desktop" will move the file "foo" to your Desktop directory but willnot rename it. You must specify a new file name to rename a file.

o To save on typing, you can substitute '~' in place of the home directory.

o Note that if you are using mv with sudo you can use the ~ shortcut,because the terminal expands the ~ to your home directory. However,

when you open a root shell with sudo -i orsudo -s, ~ will refer to the root

account's home directory, not your own.

rm: Use this command to remove or delete a file in your directory.

rmdir: The rmdir command will delete an empty directory. To delete a directory

and all of its contents recursively, use rm -r instead.

mkdir: The mkdir command will allow you to create directories. Example:

"mkdir music" will create a directory called "music".

man: The man command is used to show you the manual of other commands.

Try "man man" to get the man page forman itself. See the "Man & Getting

Help" section down the page for more information.

System Information Commands

df: The dfcommand displays filesystem disk space usage for all mounted

partitions. "df -h" is probably the most useful - it uses megabytes (M) and

gigabytes (G) instead of blocks to report. (-h means "human-readable")

du: The du command displays the disk usage for a directory. It can either display

the space used for all subdirectories or the total for the directory you run it on.

Example:

user@users-desktop:~$ du /media/floppy1032 /media/floppy/files1036 /media/floppy/user@users-desktop:~$ du -sh /media/floppy1.1M /media/floppy/

-s means "Summary" and -h means "Human Readable"

free: The free command displays the amount of free and used memory in the

system. "free -m" will give the information using megabytes, which is probably

most useful for current computers.

top: The top command displays information on your Linux system, running

processes and system resources, including CPU, RAM & swap usage and totalnumber of tasks being run. To exit top, press "q".

uname -a: The uname command with the -a option prints all system information,including machine name, kernel name & version, and a few other details. Most

useful for checking which kernel you're using.

lsb_release -a: The lsb_release command with the -a option prints versioninformation for the Linux release you're running, for example:


6/9

user@computer:~$ lsb_release -aNo LSB modules are available.Distributor ID: UbuntuDescription: Ubuntu 6.06 LTSRelease: 6.06Codename: dapper

ifconfig reports on your system's network interfaces.

Adding A New User

"adduser newuser" command will create a new general user called "newuser" on

your system, and to assign a password for the newuser account use "passwd

newuser".

Options

The default behaviour for a command may usually be modified by adding a --option tothe command. The ls command for example has an -s option so that "ls -s" will include

file sizes in the listing. There is also a -h option to get those sizes in a "human readable"format.

Options can be grouped in clusters so "ls -sh" is exactly the same command as "ls -s-h". Most options have a long version, prefixed with two dashes instead of one, so even

"ls --size --human-readable" is the same command.

"Man" and getting help

man command, info commandand command--help are the most important tools at

the command line.

Nearly every command and application in Linux will have a man (manual) file, sofinding them is as simple as typing "man "command"" to bring up a longer manual

entry for the specified command. For example, "man mv" will bring up the mv (Move)

manual.

Move up and down the man file with the arrow keys, and quit back to the commandprompt with "q".

"man man" will bring up the manual entry for the man command, which is a good place

to start!

"man intro" is especially useful - it displays the "Introduction to user commands" whichis a well-written, fairly brief introduction to the Linux command line.


7/9

There are also info pages, which are generally more in-depth than man pages. Try "infoinfo" for the introduction to info pages.

Some software developers preferinfo to man (for instance, GNU developers), so if youfind a very widely used command or app that doesn't have a man page, it's worth

checking for an info page.

Virtually all commands understand the -h (or--help) option which will produce a short

usage description of the command and it's options, then exit back to the commandprompt. Try "man -h" or"man --help" to see this in action.

Caveat: It's possible (but rare) that a program doesn't understand the -h option to mean

help. For this reason, check for a man orinfo page first, and try the long option --helpbefore -h.

Searching for man files

If you aren't sure which command or application you need to use, you can try searchingthe man files.

man -kfoo will search the man files forfoo. Try "man -k nautilus" to see how

this works.o Note that this is the same as doing apropos command.

man -ffoo searches only the titles of your system's man files. Try "man -fgnome", for example.

o Note that this is the same as doing whatis command.

Other Useful Things

Prettier Manual Pages

Users who haveKonquerorinstalled will be pleased to find they can read and search manpages in a web browser context, prettified with their chosen desktop fonts and a little

colour, by visiting man:/commandin Konqueror's address bar. Some people might find

this lightens the load if there's lots of documentation to read/search.

Pasting in commands

Often, you will be referred to instructions that require commands to be pasted into theterminal. You might be wondering why the text you've copied from a web page using

ctrl+C won't paste in with ctrl+V. Surely you don't have to type in all those nasty

commands and filenames? Relax. ctrl+shift+V pastes into a Gnome terminal; you canalso do Middle Button Click on your mouse (both buttons simultaneously on a two-

button mouse) or Right Click and selectPaste from the menu.


8/9

Save on typing

Up Arrow

orctrl+pScrolls through the commands you've entered previously.

Down

Arrow orctrl+n

Takes you back to a more recent command.

Enter When you have the command you want.

tabA very useful feature. It autocompletes any commands or filenames, if there's

only one option, or else gives you a list of options.

ctrl+r

Searches for commands you've already typed. When you have entered a very

long, complex command and need to repeat it, using this key combination and

then typing a portion of the command will search through your commandhistory. When you find it, simply press Enter.

History

The history command shows a very long list of commands that you have

typed. Each command is displayed next to a number. You can type !x to

execute a previously typed command from the list (replace the X with anumber). If you history output is too long, then use history | less for a

scrollable list.

Change the text

The mouse won't work. Use the Left/Right arrow keys to move around the line.

When the cursor is where you want it in the line, typing inserts text - ie it doesn't

overtype what's already there.

ctrl+a orHome Moves the cursor to thestartof a line.

ctrl+e orEnd Moves the cursor to the endof a line.

ctrl+b Moves to the beginning of the previous or current word.

ctrl+k Deletes from the current cursor position to the end of the line.

ctrl+u Deletes the whole of the current line.

ctrl+w Deletes the word before the cursor.
