error with an os command is dzvents [Solved]

[pvklink]

Hi,


I need to change my file sync script.
I made a dashboard with webcams and push the images to my nest hub.
My sync script sometimes moves files that are to be published.
So i gave my files to be published names like: xxx<name> . I like to exclude them from the mv command from the sync script

I found out that this works:

Code: Select all

find /media/pi/motionfiles/ -type f ! -name "xxx*" -exec mv {} /home/pi/test2/ \;

-- so i tadjust the original script below and changed the move command with

osCommand('sudo find ' .. sourceDir .. '/ -type f ! -name "xxx*" -exec mv {} ' .. targetDir .. '/ \;')    

I get this error: (it is the last part of the string, the sign: \

Code: Select all

You will have to 'escape' the \ by a \
so use

Code: Select all

osCommand('sudo find ' .. sourceDir .. '/ -type f ! -name "xxx*" -exec mv {} ' .. targetDir .. '/ \\;')
