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.
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?)
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.

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, Moritz
