cmd := exec.Command("cd", "..")

i use os/exec by document,but all command cannot be used. Error:exec: [commandname]: executable file not found in %PATH%

win11,golang 1.16.5

CodePudding user response：

The cd command is builtin to the shell. It is not a standalone executable that can be exec’ed.

Use os.Chdir to change the current working directory of the current process.
