下載sublime_text_3離線程序包
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
解壓程序包並放至/opt/下，路徑更名為/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/
建立軟鏈接，命令行下執行subl xxx.txt即可使用sublime_text編輯文件
sudo ln -s /opt/sublime_text/sublime_text /usr/bin/subl
在搜索欄建立圖標，可以用 win 鍵（Command 鍵）呼出搜索欄，輸入subl即可檢索到sublime_text
這里涉及到 Ubuntu20.04 系統在 gnome 下建立圖標，網上大部分方法僅僅是為.desktop文件添加+x權限，沒有對該文件添加屬性信息metadata::trusted，因此無法正常搜索得到結果，正確方法如下：
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"
同樣，在 Ubuntu 20.04 桌面添加圖標，同時也要添加屬性信息metadata::trusted圖標才能使用，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"
