Does anyone know which format of date should I use: I got this error:<br /><br />Warning: Illegal date format for -z, --timecond (and not a file name).<br />Warning: Disabling time condition. See curl_getdate(3) for valid date syntax.<br /><br /><br /><br />My script:<br /><br />#!/bin/bash/<br />today=$(date +%Y%m%d%H%M)<br />curl -u admin:admin -z "$today" --data "delay=3&force=false&target=/bkps/inc-$today.zip" \<br />http://localhost:4502/libs/granite/backup/content/admin/backups/<br />Seweryn Siewerthttp://www.blogger.com/profile/05220063714340415477[email protected]tag:blogger.com,1999:blog-3803541356848955053.post-57083682137537794012013-09-14T04:50:38.899-07:002013-09-14T04:50:38.899-07:00Did you get status code 200?
If you read my post...Did you get status code 200?<br /><br /><br />If you read my post you would see the first time it will get 200, then 304, as it is supposed to be by HTTP specification.<br /><br /><br /><br />Read carefully my post, see what the process really is. Don't just run commands when you are still not sure the whole thing.<br /><br /><br /><br />You really need to give more complete information, post complete commands and outputs to pastebin or something, if you do actually want my help, or I will just wild guess what's going on.livibetterhttp://yjl.im/[email protected]tag:blogger.com,1999:blog-3803541356848955053.post-8213615814767305652013-09-14T03:59:31.206-07:002013-09-14T03:59:31.206-07:00I tried it, but it doesn't seem to respond the...I tried it, but it doesn't seem to respond the 304. Else it works it seems. As for compress, it works very well, on my system it sends deflate, gzip which is very good.<br /><br />curl http://www.example.com -z index.html -o index.html --verbose --compress<br /><br />I will dig into it later, because I will need to do some inspection of my server logs. I still have a thinking it shouldn't be nesssary to store a time stamp also, if you already have stored the file itself. But maybe I haven't understood everything of this.<br /><br />But thanks for your answers so far, they have been very helpfull to me.Rune Jensen[email protected]tag:blogger.com,1999:blog-3803541356848955053.post-84811459328875971852013-09-14T03:32:35.906-07:002013-09-14T03:32:35.906-07:00I see that.

You need to post the messages so I can understand what you were seeing. Anyway, if you use the command and options I used in the post, the -z does work.livibetterhttp://yjl.im/[email protected]tag:blogger.com,1999:blog-3803541356848955053.post-56896551652385159302013-09-14T01:46:27.754-07:002013-09-14T01:46:27.754-07:00You're right, I cannot seem to find iv now eit...You're right, I cannot seem to find iv now either. However, there is another flag, which should work, the -z time cond<br /><br /><br /><br /><br />"<br />TIME CONDITIONS<br /> <br /> HTTP allows a client to specify a time condition for the document it<br /> requests. It is If-Modified-Since or If-Unmodified-Since. Curl allows you to<br /> specify them with the -z/--time-cond flag.<br /> <br /> For example, you can easily make a download that only gets performed if the<br /> remote file is newer than a local copy. It would be made like:<br /> <br /> curl -z local.html http://remote.server.com/remote.html<br />"<br /><br /><br />...It just doesn't work.

There didn't seem to be the one you are talking. But this sounds like a good idea, anyway. There is a -R as in --remote-time. However, from the description, it didn't seem to enable downloading only when the file gets updated:<br /><br />When used, this will make curl attempt to figure out the timestamp of the remote file, and if that is available make the local file get that same timestamp.<br /><br /><br /><br />So, it really doesn't help.<br /><br /><br />Besides, if choosing not to keep the file, even curl has an option to check timestamp and download only if updated. Since you don't have file, you need to keep the timestamp elsewhere.livibetterhttp://yjl.im/[email protected]tag:blogger.com,1999:blog-3803541356848955053.post-33278188065064190662013-09-12T21:49:17.763-07:002013-09-12T21:49:17.763-07:00Why not just use the last modified of the file its...Why not just use the last modified of the file itself? It has a flag AFAIKS, it's called -r<br /><br />then you do not need to store a timestamp. It's already in the file itself.Rune Jensen[email protected]
