hi everyone,
I need to do the following thing in a case insesitive mode
sed 's/work/job/g' filename
since work could appear in different form as Work WORK WorK wORK,....
I was wondering if i could do a case insensitive search of a word.
thanks in advance,
:) (4 Replies)
I'd like to print a line if a substring is matched in a case insensitive manner
something like do a case insensitive search for ABCD as a substring:
awk '{ if (substr($1,1,4) == "") print $1 }' infile > outfile
I'm not certain how to make the syntax work???
Thanks (4 Replies)
Hi,
Im still new to scripting and this forum and could so with a little help
I understand:
if ; then
good
else
bad
fi
but how do I do the same check but ignore the case of <dir2>?
Many thanks!

Hey , i am trying to do a search for the certain books , and im trying to make it case insensitive. what i have come up with so far is this :
Database.txt
RETARDED MONKEY:RACHEAL ABRAHAML:30:30:20
GOLD:FATIN:23.20:12:3
STUPID:JERLYN:20:40:3
echo -n "Title: "
read Title

Hi All,
In one shell script I have
In variable "i" I am getting a full path of a file. Now I want to compare something like
-- upper(*Nav*))
I dont want to do like below because in each CASE statement I doing so many operations.
Please guide me.
Thanks in advance... (4 Replies)
I am using HP-Unix B.11.31.
Question: How to do the case insensitive search using FIND?
Example: I would like list the files with extension of *.SQL & *.sql.
When I try with command find . -type f -name *.sql, it does not lists file with *.SQL. (5 Replies)
Dears,
In the below string, please let me know how to make the sed search case-incensitive. I have more such lines in my script instead of let me know any other easier option.
sed -n '/dn: MSISDN=/,/^\s*$/p' full.ldif > temp ; sed -n... (4 Replies)

pdl::opt::simplex
Simplex(3) User Contributed Perl Documentation Simplex(3)NAME
PDL::Opt::Simplex -- Simplex optimization routines
SYNOPSIS
use PDL::Opt::Simplex;
($optimum,$ssize) = simplex($init,$initsize,$minsize,
$maxiter,
sub {evaluate_func_at($_[0])},
sub {display_simplex($_[0])}
);
DESCRIPTION
This package implements the commonly used simplex optimization algorithm. The basic idea of the algorithm is to move a "simplex" of N+1
points in the N-dimensional search space according to certain rules. The main benefit of the algorithm is that you do not need to calculate
the derivatives of your function.
$init is a 1D vector holding the initial values of the N fitted parameters, $optimum is a vector holding the final solution.
$initsize is the size of $init (more...)
$minsize is some sort of convergence criterion (more...) - e.g. $minsize = 1e-6
The sub is assumed to understand more than 1 dimensions and threading. Its signature is 'inp(nparams); [ret]out()'. An example would be
sub evaluate_func_at {
my($xv) = @_;
my $x1 = $xv->slice("(0)");
my $x2 = $xv->slice("(1)");
return $x1**4 + ($x2-5)**4 + $x1*$x2;
}
Here $xv is a vector holding the current values of the parameters being fitted which are then sliced out explicitly as $x1 and $x2.
$ssize gives a very very approximate estimate of how close we might be - it might be miles wrong. It is the euclidean distance between the
best and the worst vertices. If it is not very small, the algorithm has not converged.
FUNCTIONS
simplex
Simplex optimization routine
($optimum,$ssize) = simplex($init,$initsize,$minsize,
$maxiter,
sub {evaluate_func_at($_[0])},
sub {display_simplex($_[0])}
);
See module "PDL::Opt::Simplex" for more information.
CAVEATS
Do not use the simplex method if your function has local minima. It will not work. Use genetic algorithms or simulated annealing or
conjugate gradient or momentum gradient descent.
They will not really work either but they are not guaranteed not to work ;) (if you have infinite time, simulated annealing is guaranteed
to work but only after it has visited every point in your space).
