Re: Python Oracle Interace on Solaris
Thanks... Im not sure if you would know how to solve this one, but when I ran my setup python scripts I got the error: library -lclntsh not found. In the instantclient folder the library exists... is this a matter of just copying the libraries to a different spot or just setting up the correct environment variables? -- http://mail.python.org/mailman/listinfo/python-list

SunLisp: A new Lisp drinking society in Ft Lauderdale, FL debuting 7PM, Pearl Harbor Day
In case you missed it, SunLisp is debuting on Pearl Harbor Day (December 7th) at 7PM. It's been added to the Lisp Meetings Calendar as well. Who: His Kennyness, his CIO Dan (can you say "Lisp jobs"? Sher ya can) and a notable group of Lispers doing a nice project in FL and anyone who cares to join them. When: First Tuesday of the month, 7PM, starting with Pearl Harbor Day, 2010 Where: http://www.thefrogandtoadpub.com/ That is just a couple of blocks below West Cypress Creek aka 62nd on the east side of Powerline. What: They serve beer, wine, and a substantial menu of great food. Why: So we can flame each other in person over beer about the right number of namespaces. Why else? RSVP for this first meet so we know if we should ask them to tidy up the back room which is smashing but lacks tellys.

Check if a command is valid
Hello,
I have to figure out if a string is callable on a Linux system. I'm
actually doing this:
def is_valid_command(command):
retcode = 100 # initialize
if command:
retcode = subprocess.call(command, shell=True)
if retcode is 0:
print "Valid command."
else:
print "Looks not so good..."
is_valid_command("ls")
Never mind the code, because this is not the original.
The side effect of subprocess.call() is that it *actually* executes
it, but I just need the return code. What are better ways of doing
this?

I'm glad you pointed that out, because you're right. I subconciously
meant a file that is in the $PATH.

I have tried this and found some unexpected issues with Python 2.6 which I
though I should point out:
Firstly, the function `check_output` in the `subprocess` module only comes with
Python 2.7, but I have found a similar function called `check_call` [1] which
seems is similar, but not the same.
[1] http://docs.python.org/library/subprocess.html#subprocess.check_call
The code now looks like this:
from shlex import split as shell_tokenize
from subprocess import check_call, CalledProcessError
def is_valid_command(command):
try:
executable = shell_tokenize(command)[0]
check_call(['which', executable]) # Raises CalledProcessError if
# something went wrong
return True
except (ValueError, IndexError, CalledProcessError): # Catch exception if
there
# was an error calling the process
return False
The idea with `which` is really great one.
Thanks a lot, for your time and your input.
