I would like to count out how many times 'PBZ' occurs and then place that number in the line above
3
(PBZ,CP,(((ME,PBZ,BtM),ON),((ME,((PBZ,DG),(CW9,PG11))),CW9,TS2,RT1)))
This is how i am doing so far on my code
Code:
grep 'PBZ' FileIn | wc -c | while read i;
do sed '1i\
$i' FileIn > Fileout
done
This is what i get for my Fileout
$i(PBZ,CP,(((ME,PBZ,BtM),ON),((ME,((PBZ,DG),(CW9,PG11))),CW9,TS2,RT1)))
I know that there are three main problems here
1) grep 'PBZ' FileIn | wc -c = 70 .... it is counting every character instead of just counting all the 'PBZ'
2) When i do my while read i command, it does not carry the count over to my sed command thus my $i was not changed in my code
3) The $i is being placed before, but on the same line as my string, i would like it to be on a separate line above my string.
If anyone has any suggestions or tips on how i could correct this it would be very much appriciated.
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

Hope that makes sense.

claev2.f(3) LAPACK claev2.f(3)NAME
claev2.f -
SYNOPSIS
Functions/Subroutines
subroutine claev2 (A, B, C, RT1, RT2, CS1, SN1)
CLAEV2
Function/Subroutine Documentation
subroutine claev2 (complexA, complexB, complexC, realRT1, realRT2, realCS1, complexSN1)
CLAEV2
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 decomposition
[ CS1 CONJG(SN1) ] [ A B ] [ CS1 -CONJG(SN1) ] = [ RT1 0 ]
[-SN1 CS1 ] [ CONJG(B) C ] [ SN1 CS1 ] [ 0 RT2 ].
Parameters:
A
A is COMPLEX
The (1,1) element of the 2-by-2 matrix.
B
B is COMPLEX
The (1,2) element and the conjugate of the (2,1) element of
the 2-by-2 matrix.
C
C is COMPLEX
The (2,2) element of the 2-by-2 matrix.
RT1
RT1 is REAL
The eigenvalue of larger absolute value.
RT2
RT2 is REAL
The eigenvalue of smaller absolute value.
CS1
CS1 is REAL
SN1
SN1 is 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 truncated 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.
