Use wallpaper-tray in Ubuntu

Today, I found that a desktop word was not used in the past. I wanted to use it as a wallpaper in the Ubuntu virtual machine, but the process was quite unsatisfactory.

 

1. garbled image file names

When I upload a desktop word image to a virtual machine, I did not use samba or VMware shared files. Instead, I used an XP Terminal to connect to RZ for uploading and found that the file names were garbled, this is the encoding format of the terminal connection program. use UTF-8.

2. Auto-increment of variables in Shell

This was found when the file name was garbled and was not noticed before.

Use the following method to perform auto-addition, subtraction, multiplication, and division of a variable in a shell script:

Index = 0

Index = 'expr $ index + 1'

3. No execution file is available after wallpaper-tray is installed.

This problem was hard to find at first.

Later, I checked the Deb package and found that there was no installation of the/bin directory. I continued to check it and found that he added help information in the/man manual.

Man wallpaper-tray found interesting information:
