Hi,
I am trying to understand what is happening here, new to scripting: I have a couple of these, but if I knew what was going on in one I can figure out the rest:
awk '/rpc-100083/ { $2 = "enable -r" }
$3 ~ /.NOS99dtlogin/ { $t = $2; $2 = $3; $3 = $t }
{ print }' /var/svc/profile/upgrade... (2 Replies)

Hi Experts,
I am adding a column of numbers with awk , however not getting correct output:
# awk '{sum+=$1} END {print sum}' datafile

hi all,
I am working on awk scripting.I have created two awk files and now have a requirement of replacing the contents of first file with some contents of second file.
Please find below the two files created.File1 has 3 records and File2 has 4 records.

Hey guys,
I want to get all the columns in this input file tab-delimited, i need to get the column send them to a variable. From there i could print them in shuffle and pick and select columns i want.

ZTREXC(l) ) ZTREXC(l)
NAME
ZTREXC - reorder the Schur factorization of a complex matrix A = Q*T*Q**H, so that the diagonal element of T with row index IFST is moved
to row ILST
SYNOPSIS
SUBROUTINE ZTREXC( COMPQ, N, T, LDT, Q, LDQ, IFST, ILST, INFO )
CHARACTER COMPQ
INTEGER IFST, ILST, INFO, LDQ, LDT, N
COMPLEX*16 Q( LDQ, * ), T( LDT, * )
PURPOSE
ZTREXC reorders the Schur factorization of a complex matrix A = Q*T*Q**H, so that the diagonal element of T with row index IFST is moved to
row ILST. The Schur form T is reordered by a unitary similarity transformation Z**H*T*Z, and optionally the matrix Q of Schur vectors is
updated by postmultplying it with Z.
ARGUMENTS
COMPQ (input) CHARACTER*1
= 'V': update the matrix Q of Schur vectors;
= 'N': do not update Q.
N (input) INTEGER
The order of the matrix T. N >= 0.
T (input/output) COMPLEX*16 array, dimension (LDT,N)
On entry, the upper triangular matrix T. On exit, the reordered upper triangular matrix.
LDT (input) INTEGER
The leading dimension of the array T. LDT >= max(1,N).
Q (input/output) COMPLEX*16 array, dimension (LDQ,N)
On entry, if COMPQ = 'V', the matrix Q of Schur vectors. On exit, if COMPQ = 'V', Q has been postmultiplied by the unitary trans-
formation matrix Z which reorders T. If COMPQ = 'N', Q is not referenced.
LDQ (input) INTEGER
The leading dimension of the array Q. LDQ >= max(1,N).
IFST (input) INTEGER
ILST (input) INTEGER Specify the reordering of the diagonal elements of T: The element with row index IFST is moved to row ILST
by a sequence of transpositions between adjacent elements. 1 <= IFST <= N; 1 <= ILST <= N.
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
