awk/sed - getting string instead of number

hrwath · #1 (**permalink**) 03-24-2008

Hi!

I am writing a script handling downloading list of files and I have to check whether file is present locally and if not finished than continue downloading. To do so I have to compare sizes of remote file and local file.

To check remote file size I have to parse something like this:

Code:

Moon:~ jaja$ curl --cookie /tmp/rpd-cookie.txt -I -L -s http://domain.com/path/to/some/file.zip
HTTP/1.1 200 OK
P3P: CP="ALL DSP COR CURa ADMa DEVa TAIa PSAa PSDa IVAa IVDa CONa TELa OUR STP UNI NAV STA PRE"
Date: Mon, 24 Mar 2008 07:49:21 GMT
Accept-Ranges: bytes
Content-Disposition: Attachment; filename=S02E02_20Simpson_20and_20Delilah.mp4
Content-Type: application/octet-stream
Content-length: 80566953
Connection: Keep-Alive

So, in a script I have a line:

Code:

REMOTESIZE=`curl --cookie /tmp/rpd-cookie.txt -I -L -s $1 | grep Content-length | awk '{print $2}'`

But the problem is that I'm getting a string with \r at the end. I tried various combinations, also with tr and sed but no results. Second value, parsed from ls is a valid integer but I can't handle the first one...

Anyone could give me some tip? It's bash-script.

Thanks

Pipe to sed 's/.$//'
