wget: Exit Status
2.13 Exit Status
================
Wget may return one of several error codes if it encounters problems.
0
No problems occurred.
1
Generic error code.
2
Parse error—for instance, when parsing command-line options, the
‘.wgetrc’ or ‘.netrc’...
3
File I/O error.
4
Network failure.
5
SSL verification failure.
6
Username/password authentication failure.
7
Protocol errors.
8
Server issued an error response.
With the exceptions of 0 and 1, the lower-numbered exit codes take
precedence over higher-numbered ones, when multiple types of errors are
encountered.
In versions of Wget prior to 1.12, Wget’s exit status tended to be
unhelpful and inconsistent. Recursive downloads would virtually always
return 0 (success), regardless of any issues encountered, and
non-recursive fetches only returned the status corresponding to the most
recently-attempted download.
