Best Regards, Luban --047d7bea3f9840a07204d99e6849 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hi all,
=A0=A0=A0 I installed two python 2.7.3 into my home directory
=A0=A0=A0=A0=A0=A0 one is for Linux: =A0 =A0 =A0 =A0 =A0 /home/luban/<= b>Linux/Python/2.7.3
=A0=A0=A0=A0=A0=A0 another is for Solaris:=A0= =A0 /home/luban/SunOS/Python/2.7.3

then I create a wrapper named "python" in /home/luban/bin to = call the different python when I am working on different systems.

[l= uban@lunbanworks 1] ~ > cat /home/luban/bin/python

#!/bin/sh

CMD=3D`basename $0`

OS=3D`uname -s`


CMD_PATH=3D"= /home/luban/$OS/Python/2.7.3/bin"


if [ -x "${CMD_PATH}= /${CMD}" ];then
=A0=A0
=A0=A0=A0 export PATH=3D"${CMD_PATH= }:${PATH}"

=A0=A0=A0 exec ${CMD_PATH}/${CMD} ${1+"$@"}

else
=A0=A0=A0 echo "${CMD} is not available for ${OS}" 1>&2<= br>
exit 1

fi

[luban@lunbanworks 2] ls -l /home/luban/bin/= python
-rwxrwxr-x=A0 1 luban lunban=A0 221 Apr=A0 5 19:11 python*


I use= below script to=A0 test the wrapper /home/luban/bin/python

[luban@l= unbanworks 3] ~ > cat myscript.py
#!/home/luban/bin/python

myname=3D"lunban"

print "myname is %s" % myn= ame

[luban@lunbanworks 4] chmod +x myscript.py

I want = to use ./ run myscript.py

[luban@lunbanworks 5] ~ >./myscript.p= y
myname=3Dluban: Command not found.
lp= r: Unable to access "myname" - No such file or directory

use /home/luban/bin/python myscript.py can work:
[luban@lunbanworks 5] ~ > /home/luban/bin/= python myscript.py
myname is luban


After I change the shebang line to #!/= home/luban/Linux/Python/2.7.3/bin/python, use ./ can execute the script.
[luban@lunbanworks 6] ~ >cat myscript.py
#!/home/luban/Linux/Python/2.7.3/bin/python
myname=3D"lunban"

print "myname is %s" % myname<= br>
[luban@lunbanworks 7] ~ >./myscript.py
myname is luban<= br>

My question is:

Why=A0 when I use #!/home/luban/Linux/Pyt= hon/2.7.3/bin/python at the beginning of myscript.py, ./myscript.py can work,

but if I use the wrapper #!/home/luban/bin/python in my python script,= use ./=A0 to run the sc= ript, it cannot not work?


I had many scripts used #!/home/luban/= bin/python when I only installed python=A0 under #!/home/luban/ for Linux, = they can run with ./, I don't want to change them,

so, how to let ./ run the p= ython script If I want to KEEP<= /span> wrapper #!/home/luban/b= in/python as the shebang line?


Best Regards,
Luban
