Hello, thank for the links,
I use reprex but I don't have a return when I use the shell() function. It doesn't display the result as in the link you gave me. I put in comment the return I get when I use the commands in the console.
shell_path <- "C:/Users/user/cmder/vendor/git-for-windows/bin/bash.exe"
shell(cmd = "ls", shell = shell_path) # 1
shell(cmd = 'echo "something"', shell = shell_path) # 2
shell(cmd = "ls rep1", shell = shell_path) # 3
