How to modify the File Creation Time and query in Solaris

How to modify the File Creation Time and query in Solaris

Lab Demonstration:

1. Check time

[[Email protected]:/] # date
Tue Jul 15 21:37:01 CDT 2014

-- If the time is incorrect, modify the format as follows:
[[Email protected]:/] # date 0715221114 -- July 15, 2014
Tue Jul 15 22:11:00 CDT 2014

2. Create an experiment environment

[[Email protected]:/] # mkdir Test

[[Email protected]:/] # cd Test

[[Email protected]:/test] # Touch test1
[[Email protected]:/test] # Touch Test2
[[Email protected]:/test] # mkdir dirtest1
[[Email protected]:/test] # mkdir dirtest2
[[Email protected]:/test] # ls
Dirtest1 dirtest2 test1 Test2

3. query the File Creation Time

-- This query shows the specific creation time.

[[Email protected]:/test] # ls-ll
Total 8
Drwxr-XR-x 2 root Root 2 Jul 15 dirtest1
Drwxr-XR-x 2 root Root 2 Jul 15 dirtest2
-RW-r -- 1 Root 0 Jul 15 test1
-RW-r -- 1 Root 0 Jul 15 Test2

Supplement:

-- Note that in a UNIX system, if the creation time is more than half a year, only the year is displayed and the specific time is not displayed, as shown below:

4. Modify the Directory and File Creation Time

[[Email protected]:/test] # ls-ll | grep dirtest1 -- view the Directory Creation Time
Drwxr-XR-x 2 root Root 2 Jul 15 dirtest1

[[Email protected]:/test] # Touch-T 200711011200.00 dirtest1 -- change the Directory Creation Time To, January 1, November 1, 2007
[[Email protected]:/test] # ls-ll | grep dirtest1 -- view the Directory Creation Time after modification. Because the creation time exceeds half a year, only the year is displayed.
Drwxr-XR-x 2 root Root 2 Nov 1 2007 dirtest1

[[Email protected]:/test] # ls-Atl test1 -- view the File Creation Time
-RW-r -- 1 Root 0 Jul 15 test1

[[Email protected]:/] # Touch-T 201406121200.00 test1 -- modify the File Creation Time to:, January 1, June 12, 2014
[[Email protected]:/] # ls-alt test1 -- view the modified time of the file, which is, January 1, June 12. This indicates that the modified File Creation Time has taken effect.
-RW-r -- 1 Root 0 Jun 12 12:00 test1

5. Summary

1. Use the touch command to modify the creation time, and run "# man touch" to view other touch commands;

2. For files that have been in UNIX systems for more than half a year, only the year is displayed during query.
