'How to make a binary executable able to write anywhere on linux?
I am writing a tool for all users on a linux server, which can download files from somewhere and save them to current directory. I build this tool as sudo user vector to get a binary executable and ask others to use alias tool="path/to/binary" to access that executable. However this executable cannot write files other than in folders under home directory of vector. How can I do to make it accessable to all users and have permissions to write to their directory?

When you create the tool, vector can own it.
The tool should reside somewhere on the user's PATH.
/usr/bin or /usr/local/bin are usually included the PATH.
You can check the path with echo $PATH to see what it is set to.
Check the permissions to make sure it is executable by everyone.
chmod 755 /path/to/binary
When the user executes the tool, it should execute as the user.
Make sure the output of the tool is not hard-code to a location the user does not have access to write.
If you can have it write to STDOUT, then the user can redirect the output to a place of their choosing
cmd> /path/to/binary > ~/output.txt
