All of which would appear to be bogus for this use due to the several times its been copied en-mass, usually by mc. But by using touch, the above derived date could be applied to the file, but which option modifies the all important creation date? Man touch doesn't appear to specifically cover that under the -D option, or am I looking at the wrong option? Done with several elseif's and some break exits for when we have a grep hit, it could be done to each folders cur dir, even more than once because that header date as part of the file, is not volatile. And just as important, it could be done insitu on a live system. And the next time kmail gets around to re-indexing that dir, all the copy damage would be undone. This would refresh my bash skills, which have been getting quite rusty as I've not written anything of note recently, like in 10 years. > “touch” will let you change Access and Modify datetimes. Humm, but I want to modify the creation times, to make that equal arrival time from the date/time of arrival from $servername in the header. Even the pinfo version can only diddle access (atime) and modify time (mtime) but no mention of ctime is made. That sounds like I am screwed. Do we have anything which can diddle the ctime's? > > The first Ref: gives a find loop to use. The second Ref: gives a > (possibly risky) method to modify the Change time.
