"touch" will create an empty file (not a random one!). Try it out. Create and change to a temporary directory, and issue "touch file" there, then issue "ls". You will see a file named "file" with a content of 0 bytes. You can remove this directory along with the file by going one level higher and issue "rm -rf <directory>"

Code:
cd /tmp
mkdir tempdir
cd tempdir
touch file
ls -l
cd ..
rm -rf tempdir

So if the name of my directory is Practical and I want to change time stamp of it with all its subdirectories and files, I can use this command.
No, not quite. Do it this way:

Code:
find /some/where/Practical -type f -name ".gitkeep" -exec touch '{}' \;  # changes existing ".gitkeep" files
find /some/where/Practical -type d -exec touch '{}' \;                   # changes existing directories

I hope this helps.

       on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device  doesn't  support	setting  the  time
