Resume a stopped process through command line
kill, linux, process, signals
Solution

Problem
I've executed the following C code in Linux CentOS to create a process. ``` #include <stdio.h> #include <unistd.h> int main () { int i = 0; while ( 1 ) { printf ( "\nhello %d\n", i ++ ); sleep ( 2 ); } } ``` I've compiled it to `hello_count`. When I do `./hello_count`, The output is like this: ``` hello 0 hello 1 hello 2 ... ``` till I kill it. I've stopped the execution using the following command ``` kill -s SIGSTOP 2956 ``` When I do ``` ps -e ``` the process `2956 ./hello_count` is still listed. Is there any command or any method to resume (not to restart) the process having process id 2956? Also, when I stop the process, the command line shows: ``` [1]+ Stopped ./hello_count ``` What does the `[1]+` in the above line mean?
