command-prompt

问题 I've been messing around with batch files a bit, and have this code running. I did not write it, I found it, and it just runs random blue numbers in command prompt until you exit. My question is this, I want to make one where every character is a random color. so essentially, it'll look like a rainbow vomited skittles on my screen. But i digress. That is my challenge, and so far i have failed at solving it. Any ideas would be great! @echo off color 01 cls :a set /a a=%random% if %a% geq 16384

问题 Why don't Windows Shell (cmd.exe) built-in commands read from stdin? (or so it seems) Example: echo bar | set /p foo= 回答1: SET /P does read the input from the pipe, but it doesn't do any good because both sides of the pipe are executed within new cmd.exe processes. So the newly defined variable is lost once the pipe sub-processes terminate.

问题 I created a virtual environment with python -m venv myenv from the command prompt, but I don't know how to activate it. I tried executing activate.bat from the command prompt but it does not activate. In other words, I don't see the current path changed to (myenv) C:\Pathname... to indicate that myenv has been activated. When I execute activate.bat the venv is not activated. 回答1: This thread it old but I had the same problem today and found a working answer for it. I've been using python 3.6

问题 Few month ago a was able to successfully sign CAB file with test certificate I have created on my server. Here are the steps I have taken: makecert.exe -sv "Demo.pvk" -n "CN=Demo Company,E=demo@gmail.com" "Demo.cer" cert2spc.exe "Demo.cer" "Demo.spc" pvk2pfx.exe -pvk "Demo.pvk" -pi "pvk_password" -spc "Demo.spc" -pfx "Demo.pfx" -po "pfx_password" signtool.exe sign /f "Demo.pfx" /p "pfx_password" /v "D:\Setup.cab" All the steps are successfull except the last one with signtool that returns:

问题 My prompt is currently displayed like here: [Aug-27 14:36] /x/y/z/w/u/v/dir1/dir2/dir3> What I would like to do is replace the constant partial-path of the current working directory /x/y/z/w/u/v with $WORK so eventually what will be displayed is [Aug-27 14:36] $WORK/dir1/dir2/dir3> /x/y/z/w/t/u is always the same path from which I usually do my work and for which I have a local variable $WORK set (very similar to the home ~ idea). A straight-forward solution will be most-welcomed as I really
