Ping whole subnet via command line

How to ping the whole subnet using a batch file? script Or command line?

If you just inherited a network or just embark on a new job and no proper documentation is on the table, then pinging the whole subnet is a good start to know the network.

How to shut down the PC if it responds to ping request?

Batch file script below pings the whole subnet and logs the status whether the IP Address is online or offline.

This can be set on the task scheduler and run at interval hours if needed.


FOR /L %I IN (1,0,254) DO   ping 192.168.1.%I -n 2 | for /f "delims=" %a in ('find /C "TTL"') do @set foobar=%a |  IF %a==2 ( echo "192.168.1.%I is online" >>d:\pingx.txt) else ( echo "192.168.1.%I is offine" >>d:\pingx.txt)


Sample output:               
" is offine"  
" is offine"  
" is online"   
" is online"   
" is online"   
" is online" 
" is offine"  
" is offine"  
" is offine"  
" is online"  
" is offine" up to 1.254

Script above can be tweak and shutdown the computer if it is online and logs the result.


FOR /L %I IN (1,1,254) DO   ping 192.168.1.%I -n 2 | for /f "delims=" %a in ('find /C "TTL"') do @set foobar=%a |  IF %a==2 ( echo "192.168.1.%I is online and shutting it down.." >>d:\pingx.txt & shutdown /m \\192.168.1.%I -s -f -t 30) else ( echo "192.168.1.%I is offine" >>d:\pingx.txt)


Above command line will check if the IP Address is online, sends the shutdown and a time limit of 30 seconds before shutting down and logs the result that the computer has been shutdown.

Cheers..till next time..

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

However, if the file (ex. an ISO file) and is more than 4GB and the filesystem  of the thumbdrive or the storage is FAT system, then robocopy or any methods of copying will not work. Since FAT has a file size limitation of less than 3GB.

Robocopy is free it can be accessed from command line. No ne…
