command

问题 I need to assign the output of a command to a variable. The command I tried is: grep UUID fstab | awk '/ext4/ {print $1}' | awk '{print substr($0,6)}' I try this code to assign a variable: UUID=$(grep UUID fstab | awk '/ext4/ {print $1}' | awk '{print substr($0,6)}') However, it gives a syntax error. In addition I want it to work in a bash script. The error is: ./upload.sh: line 12: syntax error near unexpected token ENE=$( grep UUID fstab | awk '/ext4/ {print $1}' | awk '{print substr($0,6)}

问题 I welcome rephrasing of my question, because I'm not sure exactly what the problem is called. I am trying to run a shell script via SSH using a command of the following form: ssh -o StrictHostKeyChecking=no lxplus0035 "cd ~/test; bash script1.sh" When I do this, the complex script script1.sh breaks with many syntax errors, operand errors and other errors. An example is as follows: stty: standard input: Invalid argument The script works fine when run directly, not via SSH, in the local system

问题 So I'm new to making bots and coding and stuff and this might be a newbie question but anyway, I don't have a hosting server for my bot so i was thinking that maybe when the bot turned off it would send a message in a channel But I have no clue how to do that or if its possible. I was able to get it to happen when the bot turns on but I don't know how to have it occur when the bot turns off. I don't even know where to start. What I have so far is when I type node . in the terminal the bot

问题 I don't understand how to to share instance between decoratee and decorator by using a DI container. The following example illustrates my problem. The context instance is shared between the TransactionCommandDecorator and the Command service. var context = UowFactory.GetUnitOfWork(); var command = new TransactionCommandDecorator( context, new Command(context)); command.Execute(new CommandParams { }); context.dispose(); Basically I need to have a lot of commands that interact with the database

问题 I want to be able to run a script that parses an XML file using NestJS framework for a proof-of-concept, but I'm not sure how to do it. I created a scripts directory inside /src and placed my script.ts with an initial console.log there. How can I run commands within that file? Should I change the script.ts file to plain javascript instead of typescript and then run node myscript.ts? What is the correct approach for this manner? 回答1: You can add a bin property to your package.json with the

问题 I am building an ARM template that uses Azure templates for deployment, so that it can be used as 'stock' image for users to deploy. One of the requirements is that an end user inputs the computer description as a parameter.

PowerShell Script: Param ( [string] $psVariable ) New-ItemProperty -Path "HKLM:\SYSTEM

问题 I'm trying to create a batch script that will zip all the contents in each subdirectory except the latest (or latest few). I'm currently attempting in Windows with 7-Zip but the directory is technically on a Linux server so any suggestions geared towards a Linux command is welcome. The directory structure is like this: Directory-Parent ---Sub-Directory-1 --------File1 --------File2 --------File3 ---Sub-Directory-2 --------File1 --------File2 I would like to run a batch at the Directory-Parent
