问题 How do you pass a parameter to an Azure CLI Task in Azure DevOps? Take the very basic example of showing basic info about a VM. A basic CLI command would be: az vm show --name myVM --resource-group dev -o table Now if I wanted to parameterize that command, so that I could pass in the VM Name, who would i do it? I've tried creating a CLI Task as both an in-line script and a file, passing parameters using the Azure DevOps Argument builder, but nothing seems to work. The parameter looks like

问题 I need to grep a term over thousands of files in S3, and list those file names in some output file. I'm quite new using cli, so I've been testing both on my local, and in a small subset in s3. So far I've got this: aws s3 cp s3://mybucket/path/to/file.csv - | grep -iln searchterm > output.txt The problem with this is with the hyphen. Since I'm copying over to standard output, the -l switch in grep returns (standard input) instead of file.csv My desired output is file.csv Eventually, I'll need

问题 I have been enjoying the powerful filters provided by JQ (Doc). Twitter's public API gives nicely formatted json files. I have access to a large amount of it, and I have access to a Hadoop cluster. There I decided to, instead of loading them in Pig using Elephantbird , try out JQ in mapper streaming to see if it is any faster. Here is my final query: nohup hadoop jar $HADOOP_HOME/share/hadoop/tools/lib/hadoop-streaming-2.5.1.jar\ -files $HOME/bin/jq \ -D mapreduce.map.memory.mb=2048\ -D

问题 I'm attempting to add support for reading ClearCase repositories to reposurgeon. I've been able to puzzle out most of what I think I need, but the documentation is a massive pile of confusing details that leaves one basic question obscure. How do I list all revisions in a CC repository? The minimum thing I need would be a time-ordered sequence of lines each containing a revision ID (path, branch, revision level) and its parent revision ID. Revisions for directories should be included because

问题 First, in case anyone wonders why we're invoking PowerShell in this way, I ran into this behavior with a more complex command we were building, but the behavior can be exhibited using a more simple example as shown below. In practice, we are running a command under 32-bit PowerShell as admin with additional variables rendered in the string (hence why I don't simply use single-quotes for the outer portion), but that doesn't seem to factor into the behavior below. When I invoke PowerShell

问题 As the title suggests, I'm trying to make a python script accessible from the command line. I've found libraries like click and argv that make it easy to access arguments passed from the command line, but the user still has to run the script through Python. Instead of python /location/to/myscript.py I want to be able to just do myscript from any directory From what I understand, I can achieve this on my computer by editing my PATH variables. However, I would like to be able to simply do: pip

问题 I have a project that I've been working with for quite some time and it has built and compiled (and still does on a different machine) for months. Now, when I run the command npm install it runs as normal, but at the end of the process, it builds out tons of .cmd files (and another accompanying file) in the root folder of my project. when I run ng serve i get the error: Unknown browser query basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')") I'm completely stumped as to how to get my

问题 I'm trying to grab data from HTML output that looks like this: <strong>Target1NoSpaces</strong><span class="creator"> .... <strong>Target2 With Spaces</strong><span class="creator"> .... I'm using a pipe train to whittle down the data to the targets I'm trying to hit. Here's my approach so far: grep "/strong" output.html | awk '{print $1}' Grep on "/strong" to get the lines with the targets; that works fine. Pipe to 'awk '{print $1}'. That works in case #1 when the target has no spaces, but
