Wondering how to take a set of C functions and turn them into shell/bash commands. So say I have a simple set of C functions int fn1() { // some C code for function 1. } int fn2() { // some C code for function 2. } int fn3() { // some C code for function 3. } I would like to then somehow create CLI commands so I can use them from the terminal. $ fn1 <param> <param> ... $ fn2 ... $ fn3 ... Not sure what the process is of doing this. If I need to somehow rewrite all the function interfaces in shell script, and then call of to a C function in some way, sort of like this (bash script): fn1() {

I have a completely running mvc application on ZF2. I want to run some actions from command line. I have properly set up my console routes and other environments. When I run my app from CLI, I got Permission denied exception like this: 'You are not authorized to access GeneratePdf\Controller\GeneratePdf\GeneratePdf:generate-all' in /var/www/zf2-reporting/module/BjyAuthorize/src/BjyAuthorize/Guard/Controller.php‌​:172 I already have some user in my database. How can I use those credentials to authorize a CLI user to run Actions? Edit : Following is the guards array in bjyauthorize.global.php

I was formerly using Angular version 6, now I have upgraded to 7. But when I try to create a new project in CLI using ng new [app-name] it just starts without asking if I want to include routing in my project or the styling. P.S: I have the latest version of Angular i.e 7.0.2. veeresh patil ng new {Project-name} command by default creates project without routing. You need to set routing flag as true while creating project as below(by default this routing flag will be false), ng new {Project-name} --routing=true Go through angular documentation for more details ng new --help run this command

Is there a way to pass the return value of one function to another in Redis? Of course, if you're using a language wrapper (like Ruby), it's easy — but what about from the CLI? e.g. something like this, bash style redis 127.0.0.1:6379> keys student* | mget or something like this redis 127.0.0.1:6379> mget(keys student*) keys student* will return a list of keys, but I've no idea how to fetch all the values for those keys. Thoughts? From the CLI, you just have to let the shell do its job. ./redis-cli --raw keys 'student:*' | awk '{printf "get %s\n", $1}' | ./redis-cli --raw Please note you are

When I generate my entities I have a file prefixed with ~ like a backup file or something Is it a bug or you need to manually remove them? From the official documentation in Symfony2 CLI command: $> php app/console help doctrine:generate:entities .... By default, the unmodified version of each entity is backed up and saved (e.g. Product.php~). To prevent this task from creating the backup file, pass the --no-backup option: php app/console doctrine:generate:entities Blog/Entity --no-backup So to summarize, you may add --no-backup option to your command. 来源： https://stackoverflow.com/questions

How can I rename files with "-" in front of the filename, for example: "-0001.jpg" Everyime I try to run: for i in *; do mv "$i" "${i//-/}"; done or: for i in *; do mv "$i" "${i#*-}"; done I got this error: mv: invalid option -- '0' Try `mv --help' for more information. Thanks for any light! mv ./-00008.jpg to/some/where.jpg ^ - start with path... as with most gnu commands, use the -- switch before the filename with the hyphen. it signifies "end of switches". Put a double - before the arguments that can contain "-" in the begin; then there can't be options after --. mv OPTIONS -- ... 来源： https

Is it possible to make it so that --longoption is represented as -longoption using argparse? argparse.prefix_chars doesn't work, as it is assumed that the prefix char would be repeated for a long option. I'm thinking perhaps there is a way to turn off short options and allow long options to use a single dash instead of a double dash. Something like this: parser = argparse.ArgumentParser() parser.turn_off_short_opts() Can this be done? If not, what can I use to accomplish this? Single dash long arguments aren't a problem: In [250]: p=argparse.ArgumentParser() In [251]: p.add_argument('
