For example, I could store all my global variables in a globals.js file and then call then from the website logic logic.js. Then in the index.html, i would insert the tag. How do I use the globals.js inside the logic.js? 回答1: Javascript doesn't have any implicit "include this other file" mechanisms, like css's @include. You just have to list your globals file before the logic file in the tags: <script type="text/javascript" src="globals.js" /> <script type="text

The problem that I am having is that I can run Python scripts, but only when using .\ in front of the name. This opens up CMD for a split second and then closes. If I attempt to run the file it returns that the file is not an operable program file, script, etc.. I've found multiple questions on Stack Overflow that relate to this question, but none of the solutions have worked for me. Two things I've tried: [ Environment ]:

I've looked for different libraries like Jepp or Jython, but most appear out of date. Another problem with the libraries is that I need to be able to easily include a library with the source code (though I don't need to source for the library itself) if I use a library. Because of this, would the easiest/most effective way be to simply do something like call the script with runtime.exec, and then somehow capture printed output? Or,

I basically have a file called script.sh that I would like to run inside the docker container 回答1: Remove the -it from your cli to make it non interactive and remove the TTY. If you don't need either, e.g. running your command inside of a Jenkins or cron script, you should do

I have to give this script to another Perl coder to test it in his environment. He may try to extract the logic in my program. So I want to make my script very hard to understand. Any suggestions? 回答1: I suggest that you get this person and his management to sign a legally enforceable agreement that forbids all forms of reverse engineering, and any other means of gaining access to the stuff you want to protect. Obfuscation cannot protect you against a determined attempt to

Each file under $ACTIONS_DIR is another shell script. Now, the problem here is that after using exec the script stops and doesn't go to the next file in line. Any ideas why might this be? 回答1: exec replaces the shell process. Remove it if you only want to call the command as a subprocess instead. 回答2: exec transfers control of the PID
