Hi,
I need a help with cut/awk command. I need to get certain values from a string provided. For example: i have a config file with below mentioned details
oracle="user=name"/"pass/word"@databasename.
I have used a command var1=`grep -w oracle sample.cfg | cut -d"=" -f2 | cut -d"/" -f1`.

Hi Friends,
I have a file1
i want to retrieve only the fields which have DEP,CITY,TRANS as headers in other file.
Output:
I want to give the input as DEP,CITY,TRANS column names to get the output.

Hi,
I have to display the value 16 present in "lcpu=16" which is the output of a command
# vmstat
System configuration: lcpu=16 mem=4096MB
I used as
# hdtype=`vmstat | grep "lcpu" | awk -F "=" '{print $2}'`
# echo $hdtype
16 mem
But I need to display only 16..

hay
i am trying to get JUST the PID from the ps command.
my command line is:
ps -ef | grep "mintty" | cut -d' ' -f2
but i get an empty line. i assume that the delimiter is not just one space character, but can't figure out what should i do in order to do that.
i know i can use awk or cut... (8 Replies)
Hi,
My aim is to get the md5 hash of a file and store it in a variable.
var1="md5sum file1"
$var1
The above outputs fine but also contains the filename, so somthing like this 243ASsf25 file1
i just need to get the first part and put it into a variable.
var1="md5sum file1"... (5 Replies)

Hi,
I would like use the output of my cut command as a variable in my following awk command. Here's what I've written.
cut -f1 info.txt | awk -v i=xargs -F'' '{if($6 == $i) print $20}' summary.txt
Where obviously the 'xargs' doesn't do what I want. How can I pass my cut result to my awk... (3 Replies)

DLAGV2(l) ) DLAGV2(l)
NAME
DLAGV2 - compute the Generalized Schur factorization of a real 2-by-2 matrix pencil (A,B) where B is upper triangular
SYNOPSIS
SUBROUTINE DLAGV2( A, LDA, B, LDB, ALPHAR, ALPHAI, BETA, CSL, SNL, CSR, SNR )
INTEGER LDA, LDB
DOUBLE PRECISION CSL, CSR, SNL, SNR
DOUBLE PRECISION A( LDA, * ), ALPHAI( 2 ), ALPHAR( 2 ), B( LDB, * ), BETA( 2 )
PURPOSE
DLAGV2 computes the Generalized Schur factorization of a real 2-by-2 matrix pencil (A,B) where B is upper triangular. This routine computes
orthogonal (rotation) matrices given by CSL, SNL and CSR, SNR such that
1) if the pencil (A,B) has two real eigenvalues (include 0/0 or 1/0
types), then
[ a11 a12 ] := [ CSL SNL ] [ a11 a12 ] [ CSR -SNR ]
[ 0 a22 ] [ -SNL CSL ] [ a21 a22 ] [ SNR CSR ]
[ b11 b12 ] := [ CSL SNL ] [ b11 b12 ] [ CSR -SNR ]
[ 0 b22 ] [ -SNL CSL ] [ 0 b22 ] [ SNR CSR ],
2) if the pencil (A,B) has a pair of complex conjugate eigenvalues,
then
[ a11 a12 ] := [ CSL SNL ] [ a11 a12 ] [ CSR -SNR ]
[ a21 a22 ] [ -SNL CSL ] [ a21 a22 ] [ SNR CSR ]
[ b11 0 ] := [ CSL SNL ] [ b11 b12 ] [ CSR -SNR ]
[ 0 b22 ] [ -SNL CSL ] [ 0 b22 ] [ SNR CSR ]
where b11 >= b22 > 0.
ARGUMENTS
A (input/output) DOUBLE PRECISION array, dimension (LDA, 2)
On entry, the 2 x 2 matrix A. On exit, A is overwritten by the ``A-part'' of the generalized Schur form.
LDA (input) INTEGER
THe leading dimension of the array A. LDA >= 2.
B (input/output) DOUBLE PRECISION array, dimension (LDB, 2)
On entry, the upper triangular 2 x 2 matrix B. On exit, B is overwritten by the ``B-part'' of the generalized Schur form.
LDB (input) INTEGER
THe leading dimension of the array B. LDB >= 2.
ALPHAR (output) DOUBLE PRECISION array, dimension (2)
ALPHAI (output) DOUBLE PRECISION array, dimension (2) BETA (output) DOUBLE PRECISION array, dimension (2)
(ALPHAR(k)+i*ALPHAI(k))/BETA(k) are the eigenvalues of the pencil (A,B), k=1,2, i = sqrt(-1). Note that BETA(k) may be zero.
CSL (output) DOUBLE PRECISION
The cosine of the left rotation matrix.
SNL (output) DOUBLE PRECISION
The sine of the left rotation matrix.
CSR (output) DOUBLE PRECISION
The cosine of the right rotation matrix.
SNR (output) DOUBLE PRECISION
The sine of the right rotation matrix.
