exec

问题 I need to convert a list into a string and then do the reverse process. Note that one script will convert List->String and another script will convert String->List, so store the list in a variable is not a solution. Use split(', ') or similar is not a solution either in all cases. So, as a challange I invite you to do the conversion in the following example: l = ['ab,.cd\'ac"', b'\x80', '\r\nHi, !', b'\x01'] str_l = str(l) I have tried one thing that worked: using exec() built-in function but

问题 Here I tried to spawn bash using execle() and wanted to set TMOUT environment for the new bash. It worked well. I could see TMOUT environment variable from the new bash shell. <example1> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> int main(void) { char *env[] = {"TMOUT=60", NULL}; execle("/bin/bash", "bash", NULL, env); return 0; } But if I do the same thing like example2 to use sudo, I cannot see TMOUT environment variable from the new shell. <example2>

问题 I am trying to pass arguments to execl() function for ls command. But when I pass /bin/ls -l -a as arguments to my program, the execl() function doesn't recognise the last two arguments. Why is that?Here is the code: #include <stdio.h> #include <stdlib.h> int main(int argc, char *argv[]) { int i,childpid; if(argc!=4) { printf("you didn't provide any commandline arguments!\n"); return 0; } childpid=fork(); if(childpid<0) { printf("fork() failed\n"); return 0; } else if(childpid==0) { printf(

问题 I have installed ffmpeg on my server and it works fine via my terminal. I'm able to successfully convert a file to webm format, so I'm sure the installation is fine. I'm also sure that I only have one installation of ffmpeg installed on my machine. A problem arises when I try to convert files through PHP via PHP's exec(). When I run the same commands, I ran in the terminal, nothing happens. I looked around stackoverflow and other parts of the net for some help. I tried this to see the output:

问题 I want to convert mp3 file to ogg.
