Script to save bash output to YAML file-CodePudding

I can output the relevant details of my printer using the command line: sed -En 's/[ \t]*b?(id[vp][^ \t]*|endpoint)(address)?[ \t] ([^ \t]*).* (out|in)?.*/\l\1\4 (\3)/Ip' <(lsusb | awk '$0 ~ /STMicroelectronics printer-80/{print $6}' | xargs -I % sh -c "lsusb -vvv -d %") outputs:

idVendor (0x0483)
idProduct (0x5743)
endpointOUT (0x01)
endpointIN (0x81)

Now, I need to save those data to a YAML file in the following format:

printer:
        type: Usb
        idVendor: 0x0483
        idProduct: 0x5743
        in_ep: 0x81
        out_ep: 0x01

I just don’t know how to achieve this formatting and save to the file.

I‘ve tried formatting the output, but couldn’t get further than this snippet.

CodePudding user response：

This reformats each line:

sed -E 's/(.*) \((.*)\)/    \1: \2/g' <<< "idVendor (0x0483)"

result:

    idVendor: 0x0483

Combine this with your previous command and prepend the printer: line to get the desired output:

echo "printer:" > file.yaml
sed -En 's/[ \t]*b?(id[vp][^ \t]*|endpoint)(address)?[ \t] ([^ \t]*).* (out|in)?.*/\l\1\4 (\3)/Ip' \
    <(lsusb | awk '$0 ~ /STMicroelectronics printer-80/{print $6}' | \
      xargs -I % sh -c "lsusb -vvv -d %"\
    ) | sed -E 's/(.*) \((.*)\)/    \1: \2/g' >> file.yaml

It is unclear how you want to get the line type: Usb, you can of course just write it into the file like printer:. As for the different names, simply append sed -e 's/endpointOUT/out_ep/' -e s/endpointIN/in_ep/'.
