run this in another terminal, were xxxx is the process ID of the running dd process.

the progress will report on the original terminal that you ran dd on

This version was mentioned in the comments. Credits go to flatcap.

Show running time. eta, progressbar

Create an image of "device" and send it to another machine through the network ("target" and "port" sets the ip and port the stream will be sent to), outputting a progress bar

On the machine that will receive, compress and store the file, use:

Optionally, add the -v4g switch at the end of the line in order to split the file every 4 gigabytes (or set another size: accepted suffixes are k, m and g).

The file will be compressed using 7z format, lzma2 algorithm, with maximum compression level and solid file activated.

The compression stage will be executed on the machine which will store the image. It was planned this way because the processor on that machine was faster, and being on a gigabit network, transfering the uncompressed image wasn't much of a problem.

Real gurus don't need fancy tools like iftop or jnettop.

On the another machine write this command.

pv -r /dev/zero | nc 192.168.1.1 7777

It will show live throughput between two machine.The destination machine ip is at our example 192.168.1.1

You must multiply by 8 for the network calculation.

You must install pv and netcat commands for this commands usage.

This uses PV to monitor the progress of the MySQL import and displays it though Zenity. You could also do this

pv ~/database.sql | mysql -u root -pPASSWORD -D database_name

and get a display in the CLI that looks like this

2.19MB 0:00:06 [ 160kB/s] [> ] 5% ETA 0:01:40

My Nautalus script using this command is here

need pv (pipe view) :

http://www.ivarch.com/programs/pv.shtml

Displays the realtime line output rate of a logfile.

-l tels pv to count lines

-i to refresh every 10 seconds

-l option is not in old versions of pv. If the remote system has an old pv version:

ssh tail -f /var/log/apache2/access.log | pv -l -i10 -r >/dev/null

In this example we convert a .tar.bz2 file to a .tar.gz file.

If you don't have Pipe Viewer, you'll have to download it via apt-get install pv, etc.

pv allows a user to see the progress of data through a pipeline, by giving information such as time elapsed, percentage completed (with progress bar), current throughput rate, total data transferred, and ETA. (man pv)

Only works on single files, doesn't preserve permissions/timestamps/ownership.

connects to host via ssh and displays the live transfer speed, directing all transferred data to /dev/null

needs pv installed

Debian: 'apt-get install pv'

Fedora: 'yum install pv' (may need the 'extras' repository enabled)

What happens here is we tell tar to create "-c" an archive of all files in current dir "." (recursively) and output the data to stdout "-f -". Next we specify the size "-s" to pv of all files in current dir. The "du -sb . | awk ?{print $1}?" returns number of bytes in current dir, and it gets fed as "-s" parameter to pv. Next we gzip the whole content and output the result to out.tgz file. This way "pv" knows how much data is still left to be processed and shows us that it will take yet another 4 mins 49 secs to finish.

the f is for file and - stdout, This way little shorter.

I Like copy-directory function It does the job but looks like SH**, and this doesn't understand folders with whitespaces and can only handle full path, but otherwise fine,

function copy-directory () { ; FrDir="$(echo $1 | sed 's:/: :g' | awk '/ / {print $NF}')" ; SiZe="$(du -sb $1 | awk '{print $1}')" ; (cd $1 ; cd .. ; tar c $FrDir/ )|pv -s $SiZe|(cd $2 ; tar x ) ; }

shortest alternative without the speed-o-meter"xclip large.xml"

"xclip -o" to get the clipboard content, alternatively [shift key] + insert or middle button of your mouse.
