In Linux, grep can be used to sort running processes via the terminal or command line. It can easily be done by typing ps ax then pipe grep and the filter parameters. Example: ps ax | grep "mail*" It will search for any proccess that its name starts with mail. In Windows sorting running processes can also be done using command line. Using the command prompt window, by typing "tasklist" the command will show all running process or services. Depends on your environment and running processes working on the background, it will either show more or less output. To sort the output, it needs to pipe tasklist output to another command which is "findstr.exe". Type this command below on the command prompt window to sort the output. tasklist | findstr /b "c" It will sort the tasklist output for any running processes that starts with letter "c", like chrome.exe cmd.exe, csrss.exe etc. If need to...

Use netsh in Windows 7 to export firewall policy using command line. Open an elevated command prompt and type the netshell command below. netsh advfirewall export d:\myfirewall.txt If everything works fine it will display "Ok."

  Prefix the “rsync” command with the “time” command. It would be useful to estimate total time to transfer or backup files and folders to another server or other storage device. Example: time rsync -av C20150416T025057Z.zip "/media/MyBackup"   Sample output: time rsync -av C20150416T025057Z.zip "/media/MyBackup" sending incremental file list C20150416T025057Z.zip sent 2146220138 bytes   received 31 bytes   18422490.72 bytes/sec total size is 2145958091   speedup is 1.00 real 1m56.548s user 0m25.358s sys 0m15.137s The "real" time is will display the accumulated time once the whole process is done. If a log file is used in conjunction with the rsync command, the log file would be very large and it might slow down the copying process. Since it will log a  file, then copy a file so two process are executed one after the other. Every file being copied will be appended to the log file. Anyway, if y...

Of course you need to check whether your NAS device supports NFS, you can check this from the admin panel of the NAS device. Consult the manual of your device or visit manufacturer's website. 1.
