Using solaris 2.5.1, and how can I get a summary of the size of each subdirectory, say for /export/home, all the users? usually I do a du -sk dirname but I have to manually type in each name, is there a better way?
Thanks, (3 Replies)
how do i check a file for a pattern and perform an action if it doesn't exist?
i know how to search a file for a pattern. you just place it in an array like so.
#!/usr/bin/perl
my $data_file = "file.txt";
open DATA, "$data_file";
my @array_of_data = <DATA>;
if ($_ =~ m/pattern/i) {... (4 Replies)
I am trying to find only those entries where 7018 and another number appear in the end of the line.
7018 2828 1423 2351
7018 2828 14887
2828 7018 1222
123 7018 1487
I am looking for a way to generate only the last two lines. I was trying to do just "grep '7018{1,5}" but it does not... (5 Replies)
Hello all,
Something strange going on with a shell script I'm writing. It's trying to write a list of files that it finds in a given directory to another file. But I also have a skip list so matching files that are in that skip list should be, well uhm, skipped :)
Here's the code of my... (2 Replies)

Hi,
I am using below code snippet to echo/display the files found
(matching a pattern from searchstring.out file) and the corresponding owner.

Hi All,
I am using below snippet to search for a string (read from a file 'searchstring.out') in all locations (/) and then iterate over the files found to write the locations and the respective owner to an output file.
However, this doesn't work as I believe the find command doesn't exit's... (11 Replies)
Dear all,
I wanted to use grep to search some files containing code - and the result was very disappointing: although I could see with my own eyes the expressions (written in the files), grep didn't give any output.
Basically, I write this to the terminal
grep "Find" *.txtor
grep Find... (2 Replies)

vatan_
vatan_(3MVEC) Vector Math Library Functions vatan_(3MVEC)NAME
vatan_, vatanf_ - vector arctangent functions
SYNOPSIS
cc [ flag... ] file... -lmvec [ library... ]
void vatan_(int *n,double * restrict x, int *stridex,
double * restrict y, int *stridey);
void vatanf_(int *n, float * restrict x, int *stridex,
float * restrict y, int *stridey);
DESCRIPTION
These functions evaluate the function atan(x) for an entire vector of values at once. The first parameter specifies the number of values to
compute. Subsequent parameters specify the argument and result vectors. Each vector is described by a pointer to the first element and a
stride, which is the increment between successive elements.
Specifically, vatan_(n, x, sx, y, sy) computes y[i * *sy] = atan(x[i * *sx]) for each i = 0, 1, ..., *n - 1. The vatanf_() function per-
forms the same computation for single precision data.
These functions are not guaranteed to deliver results that are identical to the results of the atan(3M) functions given the same arguments.
Non-exceptional results, however, are accurate to within a unit in the last place.
USAGE
The element count *n must be greater than zero. The strides for the argument and result arrays can be arbitrary integers, but the arrays
themselves must not be the same or overlap. A zero stride effectively collapses an entire vector into a single element. A negative stride
causes a vector to be accessed in descending memory order, but note that the corresponding pointer must still point to the first element of
the vector to be used; if the stride is negative, this will be the highest-addressed element in memory. This convention differs from the
Level 1 BLAS, in which array parameters always refer to the lowest-addressed element in memory even when negative increments are used.
These functions assume that the default round-to-nearest rounding direction mode is in effect. On x86, these functions also assume that the
default round-to-64-bit rounding precision mode is in effect. The result of calling a vector function with a non-default rounding mode in
effect is undefined.
These functions handle special cases and exceptions in the same way as the atan() functions when c99 MATHERREXCEPT conventions are in
effect. See atan(3M) for the results for special cases.
An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before calling these functions. On return, if
fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW | FE_UNDERFLOW) is non-zero, an exception has been raised. The application can then
examine the result or argument vectors for exceptional values. Some vector functions can raise the inexact exception even if all elements
of the argument array are such that the numerical results are exact.
