Library that allows execute shell commands both locally and remotelly
-
Local shell commands execution
-
Remote shell commands execution (over ssh)
-
State preserving (previous commands result are saved: cd, variables and etc.)
-
Commands are executed as its run from normal shell
-
Note: running incomplete commands (e.g.
echo "TEST- no final quote) will result execution stucking, so all commands should be verified carefully before execution -
Note: output from stdout and stderr can come in different order from it was really sent

Define message processor handler:
verify := func(error err) {
if(err != nil) {
panic(err)
}
}
handler := func(outputType int, message string) {
if(outputType == shell.Stdout) {
log.Println("stdout: ", message)
} else if(outputType == shell.Stdout) {
log.Println("stderr: ", message)
}
}
Run commands locally:
shell, err = shell.NewLocal(shell.LocalConfig{})
verify(err)
_, err := shell.Run("echo TEST 1>2", handler)
verify(err)
_, err := shell.Run("cd /var/lib", handler)
verify(err)
_, err := shell.Run(`echo "current path is: $(pwd)"`, handler)
verify(err)
status, err := shell.Run("/bin/false", handler)
verify(err)
log.Println("execution status is ", status) // execution status is 1
Run commands remotelly:
key, err := ssh.ParsePrivateKey([]byte(YOUR_PRIVATE_KEY))
verify(err)
shell, err := shell.NewRemote(shell.RemoteConfig{
Host: "root@example.com:22",
Auth: []ssh.AuthMethod{ssh.PublicKeys(key)},
})
verify(err)
_, err := shell.Run("cat /etc/hostname", handler)
verify(err)
_, err := shell.Run("cd /var/lib", handler)
verify(err)
_, err := shell.Run(`echo "current path is: $(pwd)"`, handler)
verify(err)
status, err := shell.Run("/bin/false", handler)
verify(err)
log.Println("execution status is ", status) // execution status is 1
