If I understood correctly what you specified in post #1 in this thread, you might might also want to try something more like:
If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

Hi,
I have a scenario to just plug out the file name from the following location path.
/opt/project/data/int/holdFiles/csv195687.csv
So, how do I get just file name which is "csv195687.csv" from the above line using awk/shell scripting? Can we use indexOf and Substring in awk to get... (7 Replies)
Hi All,
I have a pipe delimited file with around 30 fields. What is the simple way to Update a value for any column. For ex. If i want to update 22 field with "album".
Similarly, how to do this for the whole file and selective records of the file.

Hi Guys...
I do have a script that I need to use time or time function in my condition.
The logic will be like if the current time of execution is between 7am and 7pm then do 1,2,3,etc else do 4,5,6.
I need help is that function or how best can I do this.
Thanks in advance.

spline(1) User Commands spline(1)NAME
spline - interpolate smooth curve
SYNOPSIS
spline [-aknpx] ...
DESCRIPTION
spline takes pairs of numbers from the standard input as abcissas and ordinates of a function. It produces a similar set, which is approxi-
mately equally spaced and includes the input set, on the standard output. The cubic spline output (R. W. Hamming, Numerical Methods for
Scientists and Engineers,2nd ed., 349ff) has two continuous derivatives, and sufficiently many points to look smooth when plotted, for
example by graph(1).
OPTIONS -a Supply abscissas automatically (they are missing from the input); spacing is given by the next argument, or is assumed to be 1 if
next argument is not a number.
-k The constant k used in the boundary value computation
(2nd deriv. at end) = k*(2nd deriv. next to end)
is set by the next argument. By default k = 0.
-n Space output points so that approximately n intervals occur between the lower and upper x limits. (Default n = 100.)
-p Make output periodic, that is, match derivatives at ends. First and last input values should normally agree.
-x Next 1 (or 2) arguments are lower (and upper) x limits. Normally these limits are calculated from the data. Automatic abcissas
start at lower limit (default 0).

DIAGNOSTICS
When data is not strictly monotonic in x, spline reproduces the input without interpolating extra points.
BUGS
A limit of 1000 input points is enforced silently.
