CLI: unable to exec shell commands

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all

I have several scripts that stoped working.  All those scripts have in common 
that they call shell commands.

To find out what was going on, I did a little test
cat << "?>" | php
 <?php
 echo "exec test\n";
 exec("dir",$output,$errs);
?>
exec test
sh: /usr/local/php/bin/dir: No such file or directory

As you can see it is trying to call sh with a weird path.  It should 
use /usr/bin/dir instead

Also when I try it with 'type' (which is an internal command) it has the same 
result.

I recently switched from FC3 to FC4 for my development.  The PHP binary I'm 
using was compiled from sources with the following charasteristics:


PHP Version => 4.3.10

Configure Command =>  './configure' '--prefix=/usr/local/bin' 
'--bindir=/usr/bin' '--with-mysql' '--with-config-file-path=/etc' 
'--enable-mbstring' '--enable-mbregex' '--with-gd' '--enable-gd-native-ttf' 
'--with-ttf-dir=/usr/bin' '--with-freetype-dir=/usr/lib' 
'--with-png-dir=/usr/lib' '--with-xpm-dir=/usr/X11R6' '--enable-ftp' 
'--enable-memory-limit' '--enable-safe-mode' '--enable-bcmath' 
'--enable-calendar' '--enable-ctype' '--enable-inline-optimization' 
'--with-bz2' '--with-iconv' '--with-zlib-dir=/usr/lib' '--disable-cgi' 
'--with-cli'
Server API => Command Line Interface

Any ideas?


With kind regards


Andy

Check out these few php utilities that I released
 under the GPL2 and that are meant for use with a 
 php cli binary:
