23.3.3 Ignore Update Time Attribute Information

A file can be set so that the access time/modify time should not be updated when the file is accessed /modified, reducing access load on a file system by reducing the frequency of meta-data modification.

Use sfcsettime(1) to set ignore update time attribute information. When ignore update time attribute information is set for a directory, it is automatically reflected for the files and directories created under such a directory.

Examples of sfcsettime(1) application are shown below.

Setup to suppress modification of a file's last modified time.

% sfcsettime -a /mnt/file

Setup to suppress modification of the last access time for files to be created in a specified directory.

% sfcsettime -a /mnt/dir

For details on sfcsettime(1), see Appendix F.3.7, "sfcsettime(1)."

The mount option of "noatime" can be used when file access time modification is not needed for an entire file system.
