From: Alexandre Simon on 27 Jan 2010 16:46 Hello, I'm pretty "sure" (in realty I do not understand a lot about the problem... :( ) this is a distribution or a version problem but maybe some PHP/bash expert here could have some idea and tell me what I could try to solve the problem described here : http://ubuntuforums.org/showthread.php?p=8734334 Shortly : PHP cli seems to output something like newlines that bash can not intercept. My initial goal is to complete a PHP script, using the PHP script itselfs as function for bash completion. Mechanism that works perfectly on some other platforms (with different PHP AND bash version ...) than Ubuntu 8.04 and 9.10 (PHP 5.2.4 and PHP 5.2.10 respectively). The interest : only one thing to code : the php script. Moreover : the PHP scripts knows "things" (DB connection, .. etc) that the bash script would have some difficulty to get. Thank you a lot for any help. -- Alex

From: Alexandre Simon on 28 Jan 2010 02:26 The problem has nothing to do with "myscript.php" output. The problem is in bash completion process wich involves only "echoscrip.[php|sh]". These scripts only have (to my comprehension) to output a single string, without newline and it is what they do. The fact is, and I do not understand why because the output is exactly the same : - using echoscript.sh to provide bash COMPREPLY variable value, bash completion works, - using echoscript.php to do the same, bash completion does not work. I tried to took for a runtime option (php.ini) but didn't found anything relevant. PS : just because I had to do it, I tried to add newline and cariage return to all the scripts. The result is the same, unfortunately.

But it's not only about MySQL business : in my context, the PHP script has access to many business processes that only exists in PHP code. In this context (to my mind), it is quiet normal and simpler to get bash completion variables value from the PHP itself. We could probably continue to discuss this design issue but the problem is that, in the context of bash completion process, echoscript.php and echoscript.sh that simply echo "a b c d" (exactly the same output), give different results and I can not understand why ... I searched for runtime options (php.ini) but didn't found anything relevant. I also searched about the "shebang" but with no result. I just attached a modified version of completion.sh, the script to source in the current bash process to complete "myscript.php" (see http://ubuntuforums.org/showthread.php?p=8734334 for a complete description). If you uncomment the lines that call echoscript.php and echoscript.sh, you can compare php.out and sh.out files and see they are identical (using "diff -b php.out sh.out" for instance). When echoscript.php is not called, the bash completion process works. When it is called the completion goes wrong, even if you do not use the output in the completion process (the modified version of completion.sh uses a "static" bash string "a b c d"). Can anyone understand what could happened ? Thank you, -- Alex
