What does sleep 0 do in a shell script and what does it do if it used in the ansible SSH config to append after each command?

问题 What does sleep 0 do in a shell script? I read the man page for sleep and it says "delay for a specified amount of time" And the argument NUMBER specifies this time in SECONDS (by default). But I see ansible using sh -c 'echo ~ec2-user && sleep 0' to start with each task. Also, it uses this at the end of each remote command it is firing. I didn't find any special case mention of sleep 0 on the man page and based on the functionality of the sleep command it doesn't make any sense to have sleep

问题 I am relatively new to using scp - and I am trying to do some simple stuff over ec2 - something like the following: scp -i ec2key.pem username@ec2ip:/path/to/file ~/path/to/dest/folder/file What I would like to have is the log of the above command (i.e the screen output to a text file) - Is there a way to achieve this? Thanks. 回答1: You can redirect both outputs (stdout, stderr) of the command with &> provided you use the verbose ( -v ) argument. Otherwise, scp will suppress the output as it

Passwordless SSH using paramiko

问题 Issue : I'm a noob with Paramiko, trying to run some commands from a python script (on personal machine) on a remote server. The remote server doesn't need a password to connect to. For example, if I do root@[IPaddress] on my Mac, I'm successfully able to connect to the remote server via MacbookPro terminal. However, I'm trying to do this inside a Python script using Paramiko, and no matter what I do, I get an Authentication error or No Authentication methods available. I went through

Recovering lost AWS EC2 Key Pairs

问题 AWS rookie here. I created a few EC2 instances under my AWS account and reused the same Key Pair for all of them. I believe (IIRC) that I had generated the Key Pair from inside AWS, but that could be wrong. Over this past weekend I sold my old laptop (after completely wiping the hard disk) and got a new one. I'm just remembering now ( :facepalm ) that I forgot to copy all my SSH private keys to a flash drive and that I no longer have them. All I want/need to do is to SSH into my EC2 instances

Python: Subprocess “call” function can't find path

[亡魂溺海] 提交于 2021-02-08 11:31:25
问题 I have a python program that needs to run a bash command on a server. The program works when I run a bash command in my local directory like this: import subprocess from subprocess import call call(['bash', 'Script_Test.sh']) However, after SSH'ing to a server and running a similar line of code below with a path on the server to a bash script, I get the error "No such file or directory" call['bash', path] This doesn't make sense for a number of reasons. I triple checked that the path is
