Description hjl 2001-09-11 18:18:32 UTC 
Is there a way to increment the time for n seconds? I am thinking something
like

# touch -F n foo

which will increment the time by n seconds and

# touch -B n foo

which will decrement the time by n seconds.
Comment 1 Bernhard Rosenkraenzer 2001-09-18 09:30:17 UTC 
Use touch -t or touch --time=foo for now.
Adding -F and -B wouldn't be much of a problem, but it would be nonstandard 
extensions (or are they supported anywhere else?)
Comment 2 hjl 2001-09-18 15:15:31 UTC 
What I want is to make a file, bar, a few seconds newer than
foo. It is used for make. I'd like to do

# touch -t foo bar
# touch -F 1 bar

so that bar is 1 second newer than foo. I don't  want to bar to
to have the current time since foo might have been updated
between it was checked out and bar was generated.

Comment 4 Bernhard Rosenkraenzer 2001-09-27 15:56:40 UTC 
Works slightly different though:

To achieve your example, simply

touch -r foo -F 1 bar

I've added this patch in 4.1-6

Hi,

this is a nifty feature. Is there any particular reason for
dropping it in recent fileutils packages, or was it just by
accident when branching back to older releases?

(I think I have an updated patch available.)

Thanks,
Gru_ an bero,
