EXIT CODES
There are a bunch of different error codes and their corresponding error messages that may appear under error conditions. At the time of this writing, the exit codes are:
0
Success. The operation completed successfully according to the instructions.
1
Unsupported protocol. This build of curl has no support for this protocol.
2
Failed to initialize.
3
URL malformed. The syntax was not correct.
4
A feature or option that was needed to perform the desired request was not enabled or was explicitly disabled at build-time. To make curl able to do this, you probably need another build of libcurl.
5
Could not resolve proxy. The given proxy host could not be resolved.
6
Could not resolve host. The given remote host could not be resolved.
7
Failed to connect to host.
8
Weird server reply. The server sent data curl could not parse.
9
FTP access denied. The server denied login or denied access to the particular resource or directory you wanted to reach. Most often you tried to change to a directory that does not exist on the server.
10
FTP accept failed. While waiting for the server to connect back when an active FTP session is used, an error code was sent over the control connection or similar.
11
FTP weird PASS reply. Curl could not parse the reply sent to the PASS request.
12
During an active FTP session while waiting for the server to connect back to curl, the timeout expired.
13
FTP weird PASV reply, Curl could not parse the reply sent to the PASV request.
14
FTP weird 227 format. Curl could not parse the 227-line the server sent.
15
FTP cannot use host. Could not resolve the host IP we got in the 227-line.
16
HTTP/2 error. A problem was detected in the HTTP2 framing layer. This is somewhat generic and can be one out of several problems, see the error message for details.
17
FTP could not set binary. Could not change transfer method to binary.
18
Partial file. Only a part of the file was transferred.
19
FTP could not download/access the given file, the RETR (or similar) command failed.
21
FTP quote error. A quote command returned error from the server.
22
HTTP page not retrieved. The requested URL was not found or returned another error with the HTTP error code being 400 or above. This return code only appears if --fail is used.
23
Write error. Curl could not write data to a local filesystem or similar.
25
Failed starting the upload. For FTP, the server typically denied the STOR command.
26
Read error. Various reading problems.
27
Out of memory. A memory allocation request failed.
28

30
