Hi,
I know sed is stream text editor and not a bit more than that. Can anyone explain its usage and advantages?
How is awk different from sed?
I donno i am a bit confused about it. But i have coded in awk and shell.
Thanks,

Hi there,
I'm trying to process a comma delimited file to remove the seconds:
916901,0,488589834,TRADE,Trade, ,2002-07-2510:14:43.387,CITI.MW,970847, , , ,808.0,2526.0,0.0,0.0,-1
So basically the .*** from the 7th field
Any help appreciated

Hey all,
Can I put sed command inside the awk action ?? If not then can i do grep in the awk action ??
For ex:
awk '$1=="174" { ppid=($2) ; sed -n '/$ppid/p' tempfind.txt ; }' tempfind.txt
Assume: 174 is string.
Assume: tempfind.txt is used for awk and sed both.
tempfind.txt... (11 Replies)
Hi,
I have a data file with 5 columns - like this:

I've got an inventory database with eight columns with things like product name, manufacturer, UPC code, etc. on each line. Our PO (purchase order) number is in the first column. I can grep the date and get the full line of data but I would like to strip out everything but the PO number in the... (5 Replies)
What if I wanted to add a word such as IT after the first character and if theres 3 characters, after the 2nd character?
output would be:
G, it H
G, H it P
G, H, P it L
I'm thinking that AWK would be the easiest way to do this... Currently looking it up.
Right now I'm using awk but I... (13 Replies)
Hi All,
Is there a way of comparing two columns in the same file and deleting the row if the values of the columns match.
I have the sample data file as below.
M024900|175309.00|968.00|17
M025001|19861.79|97.90|148
M025002|431.70|159.00|3

dgeqrt.f
dgeqrt.f(3) LAPACK dgeqrt.f(3)NAME
dgeqrt.f -
SYNOPSIS
Functions/Subroutines
subroutine dgeqrt (M, N, NB, A, LDA, T, LDT, WORK, INFO)
DGEQRT
Function/Subroutine Documentation
subroutine dgeqrt (integerM, integerN, integerNB, double precision, dimension( lda, * )A, integerLDA, double precision, dimension( ldt, * )T,
integerLDT, double precision, dimension( * )WORK, integerINFO)
DGEQRT
Purpose:
DGEQRT computes a blocked QR factorization of a real M-by-N matrix A
using the compact WY representation of Q.
Parameters:
M
M is INTEGER
The number of rows of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrix A. N >= 0.
NB
NB is INTEGER
The block size to be used in the blocked QR. MIN(M,N) >= NB >= 1.
A
A is DOUBLE PRECISION array, dimension (LDA,N)
On entry, the M-by-N matrix A.
On exit, the elements on and above the diagonal of the array
contain the min(M,N)-by-N upper trapezoidal matrix R (R is
upper triangular if M >= N); the elements below the diagonal
are the columns of V.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
T
T is DOUBLE PRECISION array, dimension (LDT,MIN(M,N))
The upper triangular block reflectors stored in compact form
as a sequence of upper triangular blocks. See below
for further details.
LDT
LDT is INTEGER
The leading dimension of the array T. LDT >= NB.
WORK
WORK is DOUBLE PRECISION array, dimension (NB*N)
INFO
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value

Further Details:
The matrix V stores the elementary reflectors H(i) in the i-th column
below the diagonal. For example, if M=5 and N=3, the matrix V is
V = ( 1 )
( v1 1 )
( v1 v2 1 )
( v1 v2 v3 )
( v1 v2 v3 )
where the vi's represent the vectors which define H(i), which are returned
in the matrix A. The 1's along the diagonal of V are not stored in A.
Let K=MIN(M,N). The number of blocks is B = ceiling(K/NB), where each
block is of order NB except for the last block, which is of order
IB = K - (B-1)*NB. For each of the B blocks, a upper triangular block
reflector factor is computed: T1, T2, ..., TB. The NB-by-NB (and IB-by-IB
for the last block) T's are stored in the NB-by-N matrix T as
T = (T1 T2 ... TB).
