This is indeed a duplicate of paramiko SSH exec_command(shell script) returns before completion, but the answer there is not terribly detailed. So…
As you noticed, exec_command
is a non-blocking call. So you have to wait for completion of the remote command by using either:
Channel.exit_status_ready
if you want a non-blocking check of the command completion (i.e.: pooling)Channel.recv_exit_status
if you want to block until the command completion (and get back the exit status — an exit status of 0 means normal completion).
In your particular case, you need the later:
stdin, stdout, stderr = client.exec_command(filedelete) # Non-blocking call
exit_status = stdout.channel.recv_exit_status() # Blocking call
if exit_status == 0:
print ("File Deleted")
else:
print("Error", exit_status)
client.close()
