Hi ,
I am trying to make this change work in my script but its not working.The idea is to grep for "CREATE VIEW" and then change view name from orig to VW_orig. but the problem comes when there is no schema prefix to the view name . the code I am using is
#!/bin/ksh... (5 Replies)
Hey Guys,
Saw something weird today on the unix server. I got a normal access (non-root) to a new server.
But when I had a look at the /etc/passwd file, it did not contain my login id.
Atleast this is the first time I saw it ever happening.Has anyone come across such a situation and does... (4 Replies)
Hi,
This is a new problem that I have since few days back. I have a CVS working on HP Unix, which apparently needs libz.so. Suddenly this libz.so seems to be missing.
$ cvs
/usr/lib/hpux32/dld.so: Unable to find library 'libz.so'.

almost like the file disappeared from the... (3 Replies)
greetings,
i am trying to force the user to ensure that $CPUS equals 12 or 24. it cannot be any other value including null. after the expr statement $AMT needs to equal 1 or 2. how i read the line in question is "if $CPUS is zero/null or not equal to 12 or not equal to 24" then issue the message,...

Hi,
I am getting this error while running the following code.
i=`awk '{print $2}' test1.txt`

k=`awk '{print $6}' test1.txt`
if ; then
echo "Up."
else
echo "down"
fi
rm -f test.txt test1.txt
error is this:

Hello,
This is a programming question as well as a suse question, so let me know if you think I should post this in programming.
I have an application that I compiled under opensuse 12.2 using g77-3.3/g++3.3. The program compiles and runs just fine. I gave the application to a colleague who... (2 Replies)

Description
The and functions return trigonometric functions of radian arguments x for double data types.
The and functions return trigonometric functions for float data types.
The and functions return the arc sine in the range -pi/2 to pi/2 for double and float data types, respectively.
The and functions return the arc cosine in the range 0 to pi for double and float data types, respectively.
The and functions return the arc tangent in the range -pi/2 to pi/2 for double and float data types, respectively.
The and functions return the arc tangent of y/x in the range -pi to using the signs of both arguments to determine the quadrant of the
return value for double and float data types, respectively.
Error (due to roundoff)
When P stands for the number stored in the computer in place of pi = 3.14159 26535 89793 23846 26433 ... . and "trig" stands for one of
"sin", "cos" or "tan", then the expression "trig(x)" in a program actually produces an approximation to trig(x*pi/P), and "atrig(x)"
approximates (P/pi)*atrig(x). The approximations are close.
P differs from pi by a fraction of an ulp; the difference is apparent only if the argument x is huge, and even then the difference is
likely to be swamped by the uncertainty in x. Every trigonometric identity that does not involve pi explicitly is satisfied equally well
regardless of whether P = pi. For example, sin(x)**2+cos(x)**2 = 1 and sin(2x) = 2sin(x)cos(x) to within a few ulps regardless of how big
x is. Therefore, the difference between P and pi is unlikely to effect scientific and engineering computations.
Return Values
All the double functions return NaN if NaN is passed in.
If |x| > 1 then (x) and (x) will return the default quiet NaN.
The function defines (0,0) = NaN.
