问题 .env file is parsed when running a Symfony 4 command (if dotenv is available). This is working fine when developping, but also, I want to test my code (so another environment), hence I need to load another .env file. I love what Docker did to run a container: docker run -e MYVAR1 --env MYVAR2=foo --env-file ./env.list ubuntu bash So I am looking to achieve same thing with Symfony: php bin/console --env-file ./.env.test right now, I am doing this: export $(grep -v '^#' .env.test | xargs) &&

问题 I'm working with some output that is more verbose than I'd like, so I was trying to use grep to whittle it down. The output looks something like this… path/to/file1: No Problems Found path/to/file3: Problem Found I'd like to filter out all the output concerning files without problems. I'm able to remove one line of it by piping the output through grep -v "No Problems Found" . I thought I'd then be able to use -B and -A along the lines of grep -B 1 -A 1 -v "No Problems Found" but it turns out

问题 guys. I have seen some CLI questions here, but I still want to ask this question for more detailed answers. I have already developed class1.py, class2.py, etc. with functions implemented inside each class. e.g. Operator.py has add, minus,time, devide functions. how can I build a command line interface for these classes? also for this CLI, is it a infinite loop inside the main() for interaction? And how can the CLI give some feedback such as, suggesting the user for the next operation or to

问题 I have a folder with more than 5000 images, all with JPG extension. What i want to do, is to add recursively the "thumb_" prefix to all images. I found a similar question: Rename Files and Directories (Add Prefix) but i only want to add the prefix to files with the JPG extension. 回答1: One of possibly solutions: find . -name '*.jpg' -printf "'%p' '%h/thumb_%f'\n" | xargs -n2 echo mv Principe: find all needed files, and prepare arguments for the standard mv command. Notes: arguments for the mv

问题 I am currently trying to make an cli app with Spring Shell. I want the user to able to fast pick one of 2-3 options. My current code works fine in eclipse but when I start it in Powershell, i have to hit enter multiple times (at least 3 times) in order to select the option. After pressing enter once, nothing happens. My current Method: @ShellMethod(key = { "setService", "select" }, value = "Choose a Speech to Text Service") public void setService() { boolean success = false; do { this.console

问题 I have a python script that I want to use to make remote calls on a server, connect to Cassandra CLI, and execute commands to create keyspaces. One of the attempts that I made was something to this effect: connect="cassandra-cli -host localhost -port 1960;" create_keyspace="CREATE KEYSPACE someguy;" exit="exit;" final = Popen("{}; {}; {}".format(connect, create_keyspace, exit), shell=True, stdin=PIPE, stdout=PIPE, stderr=STDOUT, close_fds=True) stdout, nothing = final.communicate() Looking

问题 I've been busy with understanding the MusicBrainz database in the past few hours and as I noticed there's no command line application to tag or fingerprint audio files. Are there any CLI implementations on Musicbrainz's fingerprinting? And how can I create those fingerprints? I found some development tools on their website (python-musicbrainz2, libdiscid and the XML webs service) but I couldn't find a simple tool or app which creates those fingerprints (the developments tools only seem to be

问题 somebody knows why my rails 3.0.7 cli is so slow? when i run rails s or rails g it takes like 5sec till he actually executes the command... any advice? thanks 回答1: Update: I'm switching my recommendation from rrails to rails-sh as the former supports REPL which is not the use case for rrails.Also patching does seem to add performance when combined with ruby environment variables, now reflected in the answer. One possible reason may be this performance bug in ruby that has it call some code

问题 I am trying to call my C++ library from my C# application (via C++/CLI). I followed the example from this question (for my specific application). The setup of my application is: Project1: C++ Project (I compile this to a DLL) Project2: C++ Project (my CLR wrapper; just the header file per the example above; references Project1) Project3: C# Project (references Project2) Unfortunately, when I actually go to access the CLR wrapper object in my C# application, I receive the following error: The
