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...

Pipe results of Grep Command to LS Comand

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?

pipe output of grep to sed?

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.

ZLAEV2(l)								 )								 ZLAEV2(l)

NAME

       ZLAEV2 - compute the eigendecomposition of a 2-by-2 Hermitian matrix [ A B ] [ CONJG(B) C ]

SYNOPSIS

       SUBROUTINE ZLAEV2( A, B, C, RT1, RT2, CS1, SN1 )

	   DOUBLE	  PRECISION CS1, RT1, RT2

	   COMPLEX*16	  A, B, C, SN1

PURPOSE

       ZLAEV2  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*16
	      The (1,1) element of the 2-by-2 matrix.

       B      (input) COMPLEX*16
	      The (1,2) element and the conjugate of the (2,1) element of the 2-by-2 matrix.

       C      (input) COMPLEX*16
	      The (2,2) element of the 2-by-2 matrix.

       RT1    (output) DOUBLE PRECISION
	      The eigenvalue of larger absolute value.

       RT2    (output) DOUBLE PRECISION
	      The eigenvalue of smaller absolute value.

       CS1    (output) DOUBLE PRECISION
	      SN1    (output) COMPLEX*16 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.
