shell-exec

问题 I decided to fork out my php script because it takes too long to run. When I ran it shell_exec() call on a local linux machine, I did not see the infinite loop problem, but on a hosted machine, the script went into an infinite loop. I reduced the code to the minimum and I hope someone can help me see the problem here: 3 scripts are involved: test_shell.php --> issues shell_exec() to forkphp.sh --> which issues a command "path/to/php write_hello_world.php" starting from top to bottom order,

问题 I am trying to execute two dmd commands simultaneously using PHP shell_exec() . One command runs Tshark for 5 seconds. The second command runs an .exe file. Tshark is a program which captures network packs transferring over a network interface. The second program (named mtu.exe) sends network packets from my local machine to a remote machine. Thing is that when I run these commands manually , I run the first command. A moment after that, I run the second one, and all goes well and within a

问题 I have two computers. On the first computer I have apache running with all my web code.

I am essentially creating a web UI to access this data without any time delay. so I call: exec("bash initial.bash"); this is a driver script that is in my Apache folder. It calls the script on the other computer. calling: ssh otherMachine temp.bash& this script invokes the data

问题 is it possible for shell_exec to execute a given command, where the initial command would ask the for a dynamic input then followed by a command that's based on the input itself. i've researched for hours for the answer and i can't seem to find what i'm looking for. i have a requirement that's similar to the idea of the example below and any help would be appreciated since $x = shell_exec("read -p 'Enter your name : ' x; echo 'Your name is' : $x"); echoing x outputs : your name is as you can

问题 When run in shell the following command, curl -F file=@filename http://192.168.0.1 produces the following output: Accuracy = 0% (0/1) (classification) Accuracy = 0% (0/1) (classification) Accuracy = 0% (0/1) (classification) Accuracy = 0% (0/1) (classification) verdict = success!

问题 sorry for that (I believe) poor question, but google and other articles in this forum can't help me... I'll run the a php script with following code in it: $cmd="duck -u user_name -p pwd -parallel 1 -e overwrite -y --throttle 1024 --upload path to remote file absolute_path_to_local_file"; $shellResponse=shell_exec($cmd); This works well, when I call this php file in the browser.

问题 I have a python script being called form php's shell_exec command. All works well, except that it cannot import the NLTK corpora when called through shell_exec.
