Hi all,
Can someone help me with the following problem.
I am executing the following command:
(search for occurences of 'error' in files that match cl-*.log expression)
> grep -cw -i --max-count=1 'error' cl-*.log
this command outputs:
cl-apache.log:1
cl-apache_error.log:1... (3 Replies)
I'm using the command grep -l XYZ to get a list of files containing the string XYZ. Then I using the comand ls -l ABC to get the create date timestamp of the each file. I've tried combining the comands using the pipe command, grep -l XYZ | ls -l, but its not working. What am I doing wrong? (3 Replies)
Is there a way I can do this:
search for text and replace line containing matched text with a different line?
For example:
"I want to replace text"
I want to search for replace and then change the line to
I am perplexed.
Hope that makes sense.
Thanks in advance. (4 Replies)

I have read many threads, but I still didn't find the right answer. May be i didn't find the right thread, though are so many threads for the same question.

CLAEV2(l) ) CLAEV2(l)
NAME
CLAEV2 - compute the eigendecomposition of a 2-by-2 Hermitian matrix [ A B ] [ CONJG(B) C ]
SYNOPSIS
SUBROUTINE CLAEV2( A, B, C, RT1, RT2, CS1, SN1 )
REAL CS1, RT1, RT2
COMPLEX A, B, C, SN1
PURPOSE
CLAEV2 computes the eigendecomposition of a 2-by-2 Hermitian matrix [ A B ] [ CONJG(B) C ]. On return, RT1 is the eigenvalue of larger
absolute value, RT2 is the eigenvalue of smaller absolute value, and (CS1,SN1) is the unit right eigenvector for RT1, giving the decomposi-
tion
[ CS1 CONJG(SN1) ] [ A B ] [ CS1 -CONJG(SN1) ] = [ RT1 0 ] [-SN1 CS1 ] [ CONJG(B) C ] [ SN1 CS1 ] [ 0 RT2 ].
ARGUMENTS
A (input) COMPLEX
The (1,1) element of the 2-by-2 matrix.
B (input) COMPLEX
The (1,2) element and the conjugate of the (2,1) element of the 2-by-2 matrix.
C (input) COMPLEX
The (2,2) element of the 2-by-2 matrix.
RT1 (output) REAL
The eigenvalue of larger absolute value.
RT2 (output) REAL
The eigenvalue of smaller absolute value.
CS1 (output) REAL
SN1 (output) COMPLEX The vector (CS1, SN1) is a unit right eigenvector for RT1.
FURTHER DETAILS
RT1 is accurate to a few ulps barring over/underflow.
RT2 may be inaccurate if there is massive cancellation in the determinant A*C-B*B; higher precision or correctly rounded or correctly trun-
cated arithmetic would be needed to compute RT2 accurately in all cases.
CS1 and SN1 are accurate to a few ulps barring over/underflow.
Overflow is possible only if RT1 is within a factor of 5 of overflow. Underflow is harmless if the input data is 0 or exceeds
underflow_threshold / macheps.
