Hey. This is pretty easy stuff but I'm learning the basics of Unix at the moment so keep that in mind. I have to:
1) Write a C-shell script to monitor user activity on the server for 13 minutes.
2) Then print the smallest and largest number of users during these 13 minutes.
I have this:

Hey,
This is a long-shot however, I am stuck with the following problem:
I have the output from ls -la, and I want to sort some of that data out by using AWK to filter it.
ls -la | awk -f scriptname.awk
Input:
For example:
drwxr-xr-x 3 user users 4096 2010-03-14 20:15 bin/... (5 Replies)
I need to calculate the biggest number in array size n.
Example: Users enter: 1 7 4 9
The biggest number is : 9
Simple but I'm really new on this on Shell/Bash! Anything will be helpful! Thanks!

Hi,
Anybody know how to print out the record that shown smallest number among column 3 and column 4

Hello,
I have often found bash to be difficult when it comes to floating point numbers. I have data with rows of tab delimited floating point numbers. I need to find the smallest number in each row that is not 0.0. Numbers can be negative and they do not come in any particular order for a given... (9 Replies)

cgeequ.f(3) LAPACK cgeequ.f(3)NAME
cgeequ.f -
SYNOPSIS
Functions/Subroutines
subroutine cgeequ (M, N, A, LDA, R, C, ROWCND, COLCND, AMAX, INFO)
CGEEQU
Function/Subroutine Documentation
subroutine cgeequ (integerM, integerN, complex, dimension( lda, * )A, integerLDA, real, dimension( * )R, real, dimension( * )C, realROWCND,
realCOLCND, realAMAX, integerINFO)
CGEEQU
Purpose:
CGEEQU computes row and column scalings intended to equilibrate an
M-by-N matrix A and reduce its condition number. R returns the row
scale factors and C the column scale factors, chosen to try to make
the largest element in each row and column of the matrix B with
elements B(i,j)=R(i)*A(i,j)*C(j) have absolute value 1.
R(i) and C(j) are restricted to be between SMLNUM = smallest safe
number and BIGNUM = largest safe number. Use of these scaling
factors is not guaranteed to reduce the condition number of A but
works well in practice.
Parameters:
M
M is INTEGER
The number of rows of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrix A. N >= 0.
A
A is COMPLEX array, dimension (LDA,N)
The M-by-N matrix whose equilibration factors are
to be computed.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
R
R is REAL array, dimension (M)
If INFO = 0 or INFO > M, R contains the row scale factors
for A.
C
C is REAL array, dimension (N)
If INFO = 0, C contains the column scale factors for A.
ROWCND
ROWCND is REAL
If INFO = 0 or INFO > M, ROWCND contains the ratio of the
smallest R(i) to the largest R(i). If ROWCND >= 0.1 and
AMAX is neither too large nor too small, it is not worth
scaling by R.
COLCND
COLCND is REAL
If INFO = 0, COLCND contains the ratio of the smallest
C(i) to the largest C(i). If COLCND >= 0.1, it is not
worth scaling by C.
AMAX
AMAX is REAL
Absolute value of largest matrix element. If AMAX is very
close to overflow or very close to underflow, the matrix
should be scaled.
INFO
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, and i is
<= M: the i-th row of A is exactly zero
> M: the (i-M)-th column of A is exactly zero
