问题 I'm trying to send a command from one python script to another running in terminal. I'm running two python scripts on an RPi running Raspbian. The first script is a loop that waits for the user to enter a number and adds it to a total. The second script uses PySide2 to print a number when a QPushButton is released. How can i make it so that the function that runs when the QPushButton is released, sends a command (or variable) into the waiting first script and executes it? I've read some

问题 Use process = Runtime.getRuntime.exec("other.sh") to lauch other.sh who exits with 1, however, process.waitFor() returns with 0. Under Linux RedHat 7. other.sh just starts another Java process that returns by System.exit(1) . I've seen the same problem in https://coderanch.com/t/326568/java/exitValue-returns-inconsistent-values. However, it said that this was a JDK bug in 1.4 and was fixed already. However, I am using JDK 1.8. I just want to know if there are any other possibilities leading

问题 We discovered recently that a script we developed chokes in python 3.x (but not python 2.x) if it is supplied its input files via process substitution, e.g.: script.py <(cat *.gz) We've tested with commands other than gzip, such as cat, just to see if we get a similar error. They all complain that /dev/fd/63 (or /dev/fd/63.gz ) does not exist. Here's the (simplified) relevant bit of code: def open_gzip_in(infile): '''Opens a gzip file for reading, using external gzip if available''' #

问题 why running import subprocess # I'm going to run another python script in anaconda script like this: #subprocess.call("C:\\ProgramData\\Anaconda3\\Scripts\\activate.bat && python C:\test.py") # but for simplifying the sample for here I've deleted the second part # (in the case you didn't install python in the default path, you can replace v_activate_address with the correct address on your computer to see the result) v_activate_address = "C:\\ProgramData\\Anaconda3\\Scripts\\activate.bat"

问题 I use the following command to reformat a file and it creates a new file: sed -e '1s/^/[/' -e 's/$/,/' -e '$s/,$/]/' toto> toto.json It works fine on the command line. I try to use it through a python script, but it does not create a new file. I try: subprocess.call(["sed", "-e","1s/^/[/","-e", "s/$/,/","-e","$s/,$/]/ ",sys.argv[1], " > ",sys.argv[2]]) The issue is: it gives me the output in the stdout and raise an error: sed: can't read >: No such file or directory Traceback (most recent

问题 I'm trying to execute a python script which is included in datas, and bundled into a pyinstaller executable (on a mac). I need to pass parameters to this script, so I can't just exec(open(read()). Outside of pyinstaller, sys.executable is the python interpreter, so calling the python script works fine. In pyinstaller, sys.executable is the 'main' py script, so it just opens up my app again instead of calling the new script. How can I call my additional python script inside my app? This is

问题 I am trying to write code that forks a subprocess and communicates with it using pipes. I am using two pipes - one for writing to, and the other for reading from the standard streams of the subprocess. Here's what I have so far: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <signal.h> #include <string.h> void read_move(int fd) { FILE *stream = fdopen(fd, "r"); char c; setvbuf(stream, NULL, _IONBF, BUFSIZ); while ((c = fgetc(stream)) != EOF) { putchar(c); } fclose(stream)
