touch - Change File Timestamps

Summary : 

Update the access and modification times of each FILE to the current
time. If FILE not exist, then it will create an empty file with that
name.

Examples :

$ touch myfile -- Set the time stamp to current time.

$ touch -c myfile -- Same as above. But if myfile not exist, then
                     it won't create it.

$ touch -r f1 f2 -- Set f1's time to f2 instead of current time.

$ touch -r f1 -B 5 f2 -- Set f2's time to 5 secs older then f1.

$ touch -r f1 -F 5 f2 -- Set f2's time to 5 secs newer then f1.

$ touch -a myfile -- Change only access time.

$ touch -m myfile -- Change only the modification time.

$ touch -t 200412251122.33 -- Set this time instead of current time.

$ ls -lu myfile -- Shows the last access time.

Read : man touch
