+## create a hidden directory
+The root directory of Dropbox can not be assigned, but I don't want to see such dir, so create a hidden directory to place real Dropbox and make a soft link to my Workspace.
+```bash
+mkdir .dropbox-origin
+```
+
+set root dir location to .dropbox-origin
+
+```bash
+ln -s /home/newnius/Workspace .dropbox-origin/Dropbox/workspace
+```
+
+# Dropbox (terminal)
+
+## download
+
+```bash
+cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -
+```
+
+## start
+```bash
+~/.dropbox-dist/dropboxd
+```
