What is the difference between curl and wget below?

curl -o mnist.zip -L http://webdocs.cs.ualberta.ca/~bx3/data/mnist.zip

curl: (7) Failed to connect to 58.96.175.173 port 7070: Connection refused

wget -o mnist.zip http://webdocs.cs.ualberta.ca/~bx3/data/mnist.zip

successfully downloaded the mnist.zip.

What is the difference between curl and wget? why curl get refused?

AFTER trying curl -v, I got messages below.

curl -o mnist.zip -L http://webdocs.cs.ualberta.ca/~bx3/data/mnist.zip -v

But I still have no idea why curl got refused. 

shell> wget http://webdocs.cs.ualberta.ca/~bx3/data/mnist.zip -d

wget http://webdocs.cs.ualberta.ca/~bx3/data/mnist.zip got same refused as curl, But wget http://webdocs.cs.ualberta.ca/~bx3/data/mnist.zip -o mnist.zip is good. Why? What is the differnce here?

There are two major differences

  1. On some systems, wget is not installed and only curl is available.
  2. There is a major advantage of using wget. wget supports recursive download, while curl doesn’t.

wget's major strong side compared to curl is its ability to download recursively.

wget is command line only. There's no lib or anything, but curl features and is powered by libcurl.

curl supports FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS, FILE, POP3, IMAP, SMTP, RTMP and RTSP. wget supports HTTP, HTTPS and FTP.

curl builds and runs on more platforms than wget.

wget is part of the GNU project and all copyrights are assigned to FSF. 


The curl project is entirely stand-alone and independent with no organization parenting at all

curl offers upload and sending capabilities. wget only offers plain HTTP POST support.

You would be better off trying to analyse both the requests

Use curl -v to analyse what are you doing wrong and you can analyse wget request by doing wget -d which shows what is happening with wget request
