To show a progress bar and status information while using the dd
command on Linux, you can use the pv
command to monitor the progress of the data transfer.
The pv
command allows you to see the progress of data transfer in real-time, and provides information such as the transfer rate, elapsed time, and estimated time remaining.
To use the pv
command with dd
, you can pipe the output of dd
to pv
, like this:
dd if=input_file | pv | dd of=output_file
This will copy the data from input_file
to output_file
, and display a progress bar and status information on the console.
For example:
$ dd if=input_file | pv | dd of=output_file 10MB 0:00:03 [2.68MB/s] [=============> ] 26% ETA 0:00:10
In this example, pv
is showing that 10MB of data has been transferred in 3 seconds, with a transfer rate of 2.68MB/s, and that 26% of the data has been transferred, with an estimated time remaining of 10 seconds.
You can also use the --size
option to specify the size of the data to be transferred, so that pv
can estimate the time remaining more accurately.
For example:
dd if=input_file | pv --size 100M | dd of=output_file
This will copy the data from input_file
to output_file
, and display a progress bar and status information on the console, using a total size of 100MB for the data transfer.
For more information about how to use the pv
command to show a progress bar and status information while using the dd
command on Linux, you can consult the pv
documentation or seek assistance from a qualified Linux administrator.
