I'm using wget into a bash script and I check the exit code to print some message. That's what I do:
wget -U mozilla -O my_page.html https://example.com/page
echo $?
Sometimes I get the page succesfully, because it exists, and somethimes I get a void file, because a 404 error (the page does not exist).
Well, I always get the exit code number 4
, in every case.
The man page for wget says this for wget exit codes:
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.
I expect to get code 0
when I get a successful download and the code 8
when I get a 404 error.
What's happening?
I checked your command ( with small modification ) and for me it's work fine.
wget -U mozilla -O test.html https://google.com/ >>/dev/null 2>&1; echo $?
0
When try with non exist page
wget -U mozilla -O test.html https://google.com/test >>/dev/null 2>&1; echo $?
8
Maybe there is something wrong indeed with the website which you trying to testing ?
