hot to put a delimiter into output of "lsusb"

I have an "lsusb" output as below:

khalemi@hpx:/opt$ lsusb -d 0c2e:0200
Bus 002 Device 004: ID 0c2e:0200 Metrologic Instruments Metrologic Scanner
Bus 002 Device 006: ID 0c2e:0200 Metrologic Instruments Metrologic Scanner

Q) How can I use "sed" to reformat the output ( using delimiter ---) to be like

Bus 002 Device 004: ID 0c2e:0200 Metrologic Instruments Metrologic Scanner
---
Bus 002 Device 006: ID 0c2e:0200 Metrologic Instruments Metrologic Scanner

I will then pass this output to another process like php script, and explode/split it using (---) delimiter into array.

please help.

Solution

  • In php, you could do like

    Through preg_split

    $str = <<<EOT
Bus 002 Device 004: ID 0c2e:0200 Metrologic Instruments Metrologic Scanner
Bus 002 Device 006: ID 0c2e:0200 Metrologic Instruments Metrologic Scanner
EOT;
$split = preg_split('~\n~', $str);
print_r($split);

    With explode,

    $split = explode("\n", $str);

    This splits the input according to the newline character.

    Output:

    Array
(
    [0] => Bus 002 Device 004: ID 0c2e:0200 Metrologic Instruments Metrologic Scanner
    [1] => Bus 002 Device 006: ID 0c2e:0200 Metrologic Instruments Metrologic Scanner
)
