How to get remote file size from a shell script?

Is there a way to get the size of a remote file like

in shell script?

Answer Source

You can download the file and get its size. But we can do better.

Use curl to get only the response header using the -I option.

In the response header look for Content-Length: which will be followed by the size of the file in bytes.

$ URL=""
$ curl -sI $URL | grep Content-Length
Content-Length: 134

To get the size use a filter to extract the numeric part from the output above:

$ curl -sI $URL | grep Content-Length | awk '{print $2}'
