--newer-than=SPEC

[kszymukowicz]

hi

it would be great if the docs can be updated with information what format should the SPEC in --newer-than=SPEC be.
No info in google on that.

Thanks.

It is explained just below in the man page: "For option --newer-than you can either specify a file or time specification like that used by at(1) command, e.g. now-7days' orweek ago'. If you specify a file, then modification time of that file will be used."

Ahhhh - yes - I am sorry. I missed that paragraph. Thanks.

Hi
I did't find any info about SPEC in google also.

now I want use --newer-than=SPEC to download files one months ago,How should I do it?

Thanks

It's fairly complex time specifications, extending the POSIX.2 standard. The definition of the time specification can be found in /usr/share/doc/at-3.1.13/timespec

For your task "now-1month" should work.

For those that find this issue later have a look at "AT(1)" online man page:
http://linux.die.net/man/1/at
The "batch" section describes some of the abilities of the time format.

Two years later the manual is still unclear on this point.

'SPEC' should be replaced with a distinct and easy to find meta-name such as AT_SPEC (searching in many case insensitive environments practically highlights the entire document as potential matches).

In one part of the document AT_SPEC can be defined as a reference to the manual page for the at command (actually 'at' isn't installed on the system I want to use lftp on, so this could be unhelpful), but also a couple example formats should be provided.

EG:

2006-01-02T15:04:05 (absolute)
"- 1 days" (relative based on current timestamp)

I don't even know if these two examples are accurate, since the webpage transcription of the manual for the at command is written in an information-dense paragraph style instead of with easy to digest examples or construction rules.

Has anybody ever tried the "If you specify a file, then modification time of that file will be used." part ?
I have seen no example of this usage: mirror remotedir/ localdir/ --newer-than="file.csv" and my attempts failed

Edit:
I made it work. You have to specify an existing file on the LOCAL FOLDER for it to work:
mirror remotedir/ localdir/ --newer-than="localdir/file.csv"
