Ubuntu 20.04 手动安装 sublime_text 并建立搜索栏图标（解决 Ubuntu 20.04 桌面图标无法双击打开问题）

下载sublime_text_3离线程序包

wget https://download.sublimetext.com/sublime_text_3_build_3211_x64.tar.bz2
#x86: wget https://download.sublimetext.com/sublime_text_3_build_3211_x32.tar.bz2

解压程序包并放至/opt/下，路径更名为/opt/sublime_text/

sudo tar -jxvf sublime_text_3_build_3211_x64.tar.bz2 -C /opt/

sudo mv /opt/sublime_text_3/ /opt/sublime_text/

建立软链接，命令行下执行subl xxx.txt即可使用sublime_text编辑文件

sudo ln -s /opt/sublime_text/sublime_text /usr/bin/subl

在搜索栏建立图标，可以用 win 键（Command 键）呼出搜索栏，输入subl即可检索到sublime_text

这里涉及到 Ubuntu20.04 系统在 gnome 下建立图标，网上大部分方法仅仅是为.desktop文件添加+x权限，没有对该文件添加属性信息metadata::trusted，因此无法正常搜索得到结果，正确方法如下：

cd ~/.local/share/applications

cat <<EOF > sublime_text.desktop
[Desktop Entry]
Version=1.0
Type=Application
Name=Sublime Text
GenericName=Text Editor
Comment=Sophisticated text editor for code, markup and prose
Exec=/opt/sublime_text/sublime_text %F
Terminal=false
MimeType=text/plain;
Icon=/opt/sublime_text/Icon/128x128/sublime-text.png
Categories=TextEditor;Development;
StartupNotify=true
Actions=Window;Document;
EOF

chmod +x sublime_text.desktop

gio set sublime_text.desktop "metadata::trusted" TRUE

gio info sublime_text.desktop | grep "metadata::trusted"

同样，在 Ubuntu 20.04 桌面添加图标，同时也要添加属性信息metadata::trusted图标才能使用，方法如下：

cd ~/Desktop

cat <<EOF > sublime_text.desktop
[Desktop Entry]
Version=1.0
Type=Application
Name=Sublime Text
GenericName=Text Editor
Comment=Sophisticated text editor for code, markup and prose
Exec=/opt/sublime_text/sublime_text %F
Terminal=false
MimeType=text/plain;
Icon=/opt/sublime_text/Icon/128x128/sublime-text.png
Categories=TextEditor;Development;
StartupNotify=true
Actions=Window;Document;
EOF

chmod +x sublime_text.desktop

gio set sublime_text.desktop "metadata::trusted" TRUE

gio info sublime_text.desktop | grep "metadata::trusted"
