Why can't Git Bash run my executable?
WindowsGitBashMingw W64Msys2Windows Problem Overview
I am on git-for-windows Git Bash. I can't run an executable on the command line:
Pedr@Abc-07 MINGW64 /c/dev
$ ls sqlite3.exe
sqlite3.exe*
Pedr@Abc-07 MINGW64 /c/dev
$ sqlite3
bash: sqlite3: command not found
Why is it so?
Windows Solutions
Solution 1 - Windows
To run a program in the current directory in bash, you put ./ in front of it. So in your case:
$ ./sqlite3.exe
When you run sqlite3, bash will look for a program with exactly that name in all directories of the PATH environment variable, which by default includes standard locations for executables like /usr/local/bin but not your current directory. See here for more info on that.
Solution 2 - Windows
It's because you're under a is a runtime environment for gcc, that give you support to binaries native under Windows, but you can run any exe as shell using ./ (local execute) Take a look to documentation of this tool: http://sourceforge.net/p/mingw-w64/wiki2/FAQ/
Solution 3 - Windows
Your PATH is missing ./. Add it to your .profile file in the home directory (/c/Users/username):
$ cd
$ pwd
/c/Users/username
$ echo 'PATH=$PATH:./' >> .profile
Restart bash session and voilà! Now echo $PATH should output :./ as the last item. Note that you definitely need to add it as the last item for security (e.g. against malicious ls.exe).
