Getting return information from another python script

安稳与你 提交于 2021-02-19 03:34:15
问题 I'm on linux, and I have one python script that I want to call from another python script. I don't want to import it as a module (for a layer of security, and now for an academic exercise because I want to figure this out), I want to actually have one script call the other with os.system() or another function like that, and have the other script return a list of tuples to the first script. I know this might not be the optimal way to do it, but I'd like to try it out, and learn some stuff in

Adding prebuilt set of files structured in folders to android out folder

问题 I have glibc compiled for arm which is different from Android glibc or the bionic C as the glibc environment I have complied will help in providing more api's. Now I can copy the glibc environment on /system/ folder while Android is running, and on doing chroot I can run my programs on glibc environment. Currently I am compiling glibc and Android separately and then tarring the glibc and copying it on Android emulator sdcard and then untarring it on /system folder and then doing chroot on

3.Shell 接收用户的参数

1.Shell 传递参数   我们可以在执行 Shell 脚本时,向脚本传递参数,Linux系统中的Shell脚本语言已经内设了用于接收参数的变量,变量之间可以使用空格间隔。   例如$0对应的是当前Shell脚本程序的名称,$#对应的是总共有几个参数,$*对应的是所有位置的参数值,$?对应的是显示上一次命令的执行返回值, 而$1、$2、$3……则分别对应着第N个位置的参数值,如图4-15所示 尝试编写一个脚本程序示例: [root@linuxprobe ~]# vim example. sh # !/bin/ bash echo " 当前脚本名称为$0 " echo " 总共有$#个参数,分别是$*。 " echo " 第1个参数为$1,第5个为$5。 " [root@linuxprobe ~]# sh example. sh one two three four five six 当前脚本名称为example. sh 总共有6个参数,分别是one two three four five six。 第1个参数为one,第5个为five。 $* 与 $@ 区别: 相同点:都是引用所有参数。 不同点:只有在双引号中体现出来。假设在脚本运行时写了三个参数 1、2、3,,则 " * " 等价于 "1 2 3"(传递了一个参数),而 "@" 等价于 "1" "2" "3"(传递了三个参数)

compiling glibc from source with debug symbols

时间秒杀一切 提交于 2021-02-19 02:27:08
问题 I need to compile glibc from source with debug symbols . 1.Where do i specify the '-g' option for this 2.How do i later make a sample code link to this particular glibc rather than the one installed on my system? 回答1: I need to compile glibc from source with debug symbols You will have hard time compiling glibc without debug symbols. A default ./configure && make will have -g on compile line. How do i later make a sample code link to this particular glibc rather than the one installed on my

How can you get real time copy progress of a large file with Python?

妖精的绣舞 提交于 2021-02-19 02:24:27
问题 I've searched high and low, and each time I find something that looks promising it's not panned out. Ultimately I want to grab the real time progress of a file copy on a linux machine from inside python. I'll take that progress and emit it to a client web page with Flask-SocketIO, likely threaded to avoid blocking. I don't mind if it's rsync, copy, or any other means...(shutil etc) to handle the actual copy. I just want a hook to push an update over the socket. Thus far I've found this to be

Run a Qt app in a different language?

问题 I'm working on a Qt application that used to be a KDE application. In the old days, I just had to use some syntax like: KDELANG=de ./my_app That ran my_app in German, and only my_app. It might not have been KDELANG, but it was some environment variable like that. I've spent a ridiculous amount of time trying to coax this answer out of Google, and I give up. There must be some way to run a Qt (4.5 if that matters) application in some other language without switching over my entire locale to

问题 I have windows .crl file. Can I convert it into a .pem file to nginx using openssl? openssl crl -in crl.crl -noout -text unable to load CRL 139765490861728:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: X509 CRL 回答1: The error means that your crl file is not encoded properly in PEM format with right header and footer. Have the right PEM encoded crl file. If the CRL is in DER format: openssl crl -in your_current.crl -inform DER -out crl.pem Now you can use crl
