note 51772 added to ref.exec

So it seems that a lot of people are trying to running bash commands in the background from php. Me too. "margus at kohv dot com" posted a note about using perl to fork and exit. I messed around a little and came up with this. It seems to work really well. function exec_background ($cmd) { exec("echo 'fork and exit 1; system(\"$cmd\");' | perl >/dev/null"); } I pu:t this in a .inc file and do a require() when I use it. The function can then be called as such: <? exec_background("ssh FQDN reboot"); ?> Note: (obviously) this is for linux (possibly other unices). The command will be executed with the permissions of the user who started apache (I think). Also note that you wont get any output from the command (but then again, you wouldn't really expect any). For Windows: this is a little more involved. First, reboot your computer into dos-mode. At the command-line, type: format c: and install a real operating system. ---- Manual Page -- http://www.php.net/manual/en/ref.exec.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51772 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51772&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51772&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51772&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51772&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51772&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51772&report=yes Search -- http://master.php.net/manage/user-notes.php
