Discussion on: Linux Basics

[Chittoji Murali Sree Krishna]

touch filename - will create an empty file
touch -a filename - change the access time only
touch -c filename - if the file does not exist, do not create it
touch -d filename - update the access and modification times
touch -m filename - change the modification time only
touch -r - use the access and modification timestamp of file
touch -t - creates a file using a specified time

it creates a file and also can modify the timestamps

[Shrihan]

Exactly!

most of the people will not use these options & they won't bother about timestamps, so I haven't mentioned them previously.
