Prettify JSON from curl in OSX

You need to put quotes around your URL:

curl -s "https://api.vk.com/method/photos.getAlbums?uid=6015870&access_token=0275127e915981fe795840165e532169482cbdfc4ca1dbd48619a687a65fead88c468cdafe9743e231c37" | python -m json.tool

The & character is a shell meta character, it puts the command in the background. As a result you are not passing the full URL to the server but put the command curl -s https://api.vk.com/method/photos.getAlbums?uid=6015870 in the background instead.

This is why the shell echos [4] 8822 to you; you put a fourth job so far into the jobs queue, it was given the PID 8822.

The remaining command is then:

access_token=0275127e915981fe795840165e532169482cbdfc4ca1dbd48619a687a65fead88c468cdafe9743e231c37 | python -m json.tool

which will not produce valid JSON indeed:

$ access_token=0275127e915981fe795840165e532169482cbdfc4ca1dbd48619a687a65fead88c468cdafe9743e231c37 | python -m json.toolNo JSON object could be decoded

You can see the job you put into the background complete on the next line:

With the quotes the command produces:

$ curl -s "https://api.vk.com/method/photos.getAlbums?uid=6015870&access_token=0275127e915981fe795840165e532169482cbdfc4ca1dbd48619a687a65fead88c468cdafe9743e231c37" | python -m json.tool{    "error": {        "error_code": 5,         "error_msg": "User authorization failed: access_token was given to another ip address.",         "request_params": [            {                "key": "oauth",                 "value": "1"            },             {                "key": "method",                 "value": "photos.getAlbums"            },             {                "key": "uid",                 "value": "6015870"            },             {                "key": "access_token",                 "value": "0275127e915981fe795840165e532169482cbdfc4ca1dbd48619a687a65fead88c468cdafe9743e231c37"            }        ]    }}

Presumably for you it'll produce more useful information as clearly I don't have the right access token for my IP address. :-)

Quote your URL. This one is broken:

curl https://api.github.com/repos/mojombo/jekyll/issues?state=closed&assignee=mojombo | python -mjson.tool

This one is correct:

curl 'https://api.github.com/repos/mojombo/jekyll/issues?state=closed&assignee=mojombo' | python -mjson.tool
