jq print character inside output

Question

I want print \"/\" separator inside output title.

curl  -s http://cd0a4a.ethosdistro.com/?json=yes \\
    | jq -c \'.rigs|.\"0d6b27\",.\"50dc35\"|[.         


        

Answer 1

You're doing a lot of unnecessary calls just to process the data. Your commands could be drastically simplified.

• You don't need to explicitly key into the .rigs object to get their values, you could just access them using [].
• You don't need the sed call to strip the quotes, just use the raw output -r.
• You don't need the awk call to add the header, you could just output an additional row from jq.

So your command turns into this instead:

$ curl -s http://cd0a4a.ethosdistro.com/?json=yes \
| jq -r '["version", "GPU_driver", "miner", "gpu"],
         (.rigs[] | [.version, .driver, .miner, "\(.gpus)/\(.miner_instance)"])
             | @csv' \
| csvlook -I

Answer 2

Here are some suggestions for simplification:

• use the --raw-output option to jq to remove extraneous back-slashes
• there is no need to remove the quotes, csvlook does it for you
• no need for awk to add a title line, use a sub-shell
• no need to specify rigs implicitly, use .[]

Here is an example:

(
  echo version,GPU_driver,miner,gpu
  curl -s 'http://cd0a4a.ethosdistro.com/?json=yes' |
  jq -r '
    .rigs | .[] |
    [ .version, .driver , .miner  , "\(.gpus)/\(.miner_instance)" ] |
    @csv
  '
) |
csvlook

Output:

|----------+------------+----------+------|
|  version | GPU_driver | miner    | gpu  |
|----------+------------+----------+------|
|  1.2.3   | nvidia     | ethminer | 2/2  |
|  1.2.4   | amdgpu     | ethminer | 1/1  |
|----------+------------+----------+------|

Answer 3

Since you already use string interpolation for that specific field, simply include the character you need (slash /) inside the string, like this:

curl ... | jq -c '... [.version,.driver,.miner,"\(.gpus)/\(.miner_instance)"] ...'

In your case (the complete line):

curl -s http://cd0a4a.ethosdistro.com/?json=yes | jq -c '.rigs|."0d6b27",."50dc35"|[.version,.driver,.miner,"\(.gpus)/\(.miner_instance)"]|@csv' | sed 's/\\//g;s/\"//g' | gawk 'BEGIN{print  "version" "," "GPU_driver" "," "miner" "," "gpu"} {print $0}' | csvlook -I
