Save linux output to jpg or image file

 There are cases where from the Linux terminal, it is required to post the output as an attachment in jpg or png. If ImageMagick is installed, this can be done easily, otherwise they use the traditional command pr to provide the output to printer.

Pre-requisite

Install ImageMagick

Combine the command convert with the output. E.g. output of the route command can be saved as png

route  | convert label:@- myroutetable.png

Next to add data into the png image.

$ convert myroutetable.png \

>  -set 'Copyright' 'CC-BY-SA 4.0'\

>  -set 'Title' 'Routing Table for Linux' \

> routetable.png

The content can then be viewed by the command hexdump

hexdump -C routetable.png

Or

strings routetable.png
