Questions[windows-subsystem-for-linux](ubuntu)

I have Windows Subsystem for Linux, but I don't know which version I have, and many things won't work in version 1. How do I check my version?

I am running Ubuntu 18.04, as a Subsystem for Windows. I have done this in mutliple PCs and never had this problem. I try to to git clone <repo>, and I get this:

Cloning into '<repo>'...
error: chmod on /mnt/c/Users/Efsta/Code/<repo>/.git/config.lock failed: Operation not permitted
fatal: could not set 'core.filemode' to 'false'

I tried the following:

1. ❯ git config core.fileMode false, with this result fatal: not in a git directory

2. ❯ git config --global core.filemode false

3. ❯ git config --add --global core.filemode false

Nothing seems to work. I already tried a couple of answers here, but WSL seems a little bit more tricky. Anyone have any idea about how to solve this?

I have also tried everything in this question : https://stackoverflow.com/questions/1580596/how-do-i-make-git-ignore-file-mode-chmod-changes, nothing seems to work.

I've just lost my phone. I know it's here in my house cause I used it last night and my bluetooth speakers will connect to it this morning.

How can I text my phone using bash? Then the phone notification will sound and I can find my phone.

Note: I asked for a bash solution because it's simpler than installing and configuring a GUI. Also I am more comfortable working in bash than python, HTML, or java, etc. Finally a bash solution works in Windows 10 when you use the Windows Subsystem for Linux (WSL).

Note 2: Reply to comments:

• I don't have a landline so I can't simply call my smartphone.
• It was 6 am on Sunday morning when I lost my phone. People I could email to call my phone were sleeping. I was unsure of the battery charge level and if it died, I could never text it.
• A few weeks previously I had turned off email sound notifications on my smartphone so I couldn't email myself.
• I don't have skype or any VOIP service providers

After 30 minutes I did find the smartphone by texting it using the answer I posted below. It was hidden underneath 4" high-from-floor furniture shelf in the living-room...
