Imagick日志将图像名称处理为文件，并从后续运行中排除这些文件

I am able to achieve like:

find . -cmin -60 -name "*.jpg" -exec  convert  -resize 300x200 -quality 85% -verbose 
{} {} \; &>>processed.txt

so in the file say there is only one file matching it, the processed file contents is like

./a.jpg JPEG 1920x636 1920x636+0+0 8-bit DirectClass 612KB 0.040u 0:00.050
./a.jpg JPEG 1920x636=>300x99 300x99+0+0 8-bit DirectClass 8.19KB 0.130u 0:00.030

is there a way so that I can have just the file name processed for example only a.jpg and then exclude a.jpg in subsequent running the command.

if the same can be achieved using Imagick php class
