Run Bash Command from PHP

Question

I have a bash script  that I run like this via the command line     script sh var1 var2   I am trying to execute the above command  after I call a certain php file   What I have right now is    output   shell exec    script sh var1 var2    echo   lt pre gt  output lt  pre gt      But it doesn  t work  I tried it using exec and system too  but the script never got executed   However when I try to run shell exec  ls    it does work and  output is a list of all files   I am not sure whether this is because of a limitation of the VPS I am using or if the problem is somewhere else

Your shell exec is executed by www-data user  from its directory  You can try  putenv  PATH  home user bin       ENV  PATH          Where your script is located in  home user bin Later on you can   output     lt pre gt   shell exec  scriptname v1 v2     lt  pre gt    echo  output    To display the output of command   Alternatively  without exporting path  try giving entire path of your script instead of just   script sh

You probably need to chdir to the correct directory before calling the script  This way you can ensure what directory your script is  in  before calling the shell command    old path   getcwd    chdir   my path      output   shell exec    script sh var1 var2    chdir  old path

Check if have not set a open basedir in php ini or  htaccess of domain what you use  That will jail you in directory of your domain and php will get only access to execute inside this directory
