How can I resume downloads in Perl?
- by Neeraj
I have a project that depends upon some other binaries to be downloaded from web at install time.For this what i do is:
if ( file-present-in-src/)
# skip that file
else
# use wget to download the file
The problem with this approach is that when I interrupt a download in middle, and do invoke the script next time, the partially downloaded file is also skipped (which is not desired), also I want wget to resume the download of the partially downloaded file.
How should I go about it:
Possible Solutions I could think of:
Let the file to be downloaded to some file say download_tmp. Move to original file
if successful.
Handle SIG{'INT'} to write proper cleanup code.
But none of these could help resume the partial file download,
Any insights?
