当解释器处于非标准位置时，如何解决“错误的解释器”错误？

Question

So my first problem is that I'm hosting on GoDaddy.

Second problem is that when I try to execute the following PHP script via SSH...

./searchreplacedb2cli.php -h hostname -u username -d databasename -p 'password'

...I get a /usr/bin/php: bad interpreter: No such file or directory error. This is because on shared hosting, there is no /usr/bin/php . Instead, the php cli I want is located here:

/usr/local/php5_3/bin/php

So, I manually changed the shebang declaration in the script to...

#!/usr/local/php5_3/bin/php -q

...and sure enough, it works.

However, I don't want to have to edit this script manually. I'm looking for a way to circumvent this issue programmatically. I use this script to deploy Wordpress sites on the fly. I wget it from a git repository each time I use it. Furthermore it is deleted and installed regularly from a bash script, so modifying it in a text editor each time is not an option.

Is there a way to pass an alternate interpreter to a bash command? Like, "if you don't find the default interpreter, use this one instead".

I tried this but it doesn't work:

./searchreplacedb2cli.php -h hostname -u username -d databasename -p 'password' | /usr/local/php5_3/bin/php

And because it's shared hosting I lack the permissions to symlink /usr/bin/php to the right place.

My next idea was to, via bash, edit line 1 of the php script using a sed replace command. I thought I would inquire here first for alternatives. Thanks.

如果它只是这个主机，请将/ usr / local / php5_3 / bin /添加到$ PATH，并使用此shebang：

#!/usr/bin/env php
