This doesn't work:

$ ls "~/.wine/drive_c/tools/Family Tree v2.0"
ls: cannot access '~/.wine/drive_c/tools/Family Tree v2.0': No such file or directory

But this does:

$ ls "/home/daniel/.wine/drive_c/tools/Family Tree v2.0"
Dossiers                           Dossiers_orig   Infos.opt      Racines.exe  'Register OCX.bat'   racines.CNT

Given that ~ is supposed to be the same as /home/daniel, what's going on here?

Context: I'm trying to make an application automatically start when I login. For this I need to select the path for the application.

Here are the paths I already looked into:

• /sbin
• /usr/sbin
• /usr/local/bin
• /usr/share/

If this may help, the application I'm trying to find is called "ScreenCloud" and I downloaded it from the Ubuntu Software Center.

But I cannot find it, is there any way I can know where is installed a particular software? Because even if I found for this one, I would like to avoid having the same issue in the future.

I'm just trying to follow this tutorial and set up my environment. My system is WSL Ubuntu 18.04. Here is already an answer on my question, but I as an absolute novice in Linux/UNIX don't know which variant presented there more suitable for my goal. Do I need to add this string

export PATH="$PATH:/path/to/dir"

into my ~/.profile or ~/.bashrc file?

Or may I need to accomplish the second step from the answer?

cd /usr/bin
sudo ln -s /path/to/binary binary-name

And then run these commands?

source ~/.profile 
or
source ~/.bashrc

For reference, I know very little about Linux, and am using it to run a program written by someone else. The instructions say Add the executable 'ttt' to the search path. In most installations this can be accomplished by linking the file to the 'bin' subdirectory at user home.

How do I go about doing this?

This executable is currently in a subfolder in the host area, as it's running on a dual-boot computer I cannot change the fact that it is a dual boot, as it is a work computer.

Is there a way to change file picker dialog path input? I would like to type the path myself instead of clicking buttons to specify the destination path. In Nautilus I can hit Ctrl+L, to show the path text box. In Save page as dialog the same shortcut takes me to name text box.
