Hi,
I am new to shell scripting.I have worked somewhat with Perl though.
I am not able to find what the second line does and how does it do.
<code>
FP_RUNNING=`service filepool status`
FP_RUNNING=${FP_RUNNING%% *}
<\code>
After the first line,the variable FP_RUNNING stores '1 FilePool... (2 Replies)
Hi,
Im pretty new to Unix. I came across a script which was using PLSQL inside a script and there was an unusual thing mentioned.
there was a variable assigned as
P_CUR=${1}
and one more as
V_TAGFILE="$1"
Couldnt find the difference. Also the variables were used in PLSQL... (1 Reply)
Must be a bug or something. Whether I escape them or not, it will not work. No matter what I set the minimum and maximum to nothing gets caught. For instance:
find / -regex "/.{0, 50}.*" -maxdepth 1 or find / -regex "/.\{0, 50\}.*" -maxdepth 1 should pretty much catch everything residing within... (4 Replies)
Hi everyone:
I'm stuck at this point, could you guys please give me some hints about what I am doing wrong in the following script, I'm using sed for windows:

I'm having trouble understanding the exclude option in tar. From some web sites, it seems one is able to exclude several strings by enclosing them in curly brackets. However it seems to be "random" what gets excluded when using the curlies.
I've been using the exclude-from=myfile option in a... (12 Replies)
Hi everyone,
I've got a file that looks like this:

I want to pull the value of pid between the curly braces, or 22224 in this example. pid is always the second pair of curly braces, but the length of the number is... (7 Replies)

Hi,
I have below command in one of the script. Can you please let me know what does the curly braces do over here \{1,\}. The remaining part of the code atleast I am able to understand.

Hello, i was trying to find get a command to list duplicated files so i tried
ls dir1 dir2 | awk '{x++}'
and it didnt work.
After a bit of searching online i found that it works without the curly braces
ls dir1 dir2 | awk 'x++'
I thought the curly braces were needed in awk so... (6 Replies)

SGESV(l) ) SGESV(l)
NAME
SGESV - compute the solution to a real system of linear equations A * X = B,
SYNOPSIS
SUBROUTINE SGESV( N, NRHS, A, LDA, IPIV, B, LDB, INFO )
INTEGER INFO, LDA, LDB, N, NRHS
INTEGER IPIV( * )
REAL A( LDA, * ), B( LDB, * )
PURPOSE
SGESV computes the solution to a real system of linear equations A * X = B, where A is an N-by-N matrix and X and B are N-by-NRHS matrices.
The LU decomposition with partial pivoting and row interchanges is used to factor A as
A = P * L * U,
where P is a permutation matrix, L is unit lower triangular, and U is upper triangular. The factored form of A is then used to solve the
system of equations A * X = B.
ARGUMENTS
N (input) INTEGER
The number of linear equations, i.e., the order of the matrix A. N >= 0.
NRHS (input) INTEGER
The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
A (input/output) REAL array, dimension (LDA,N)
On entry, the N-by-N coefficient matrix A. On exit, the factors L and U from the factorization A = P*L*U; the unit diagonal ele-
ments of L are not stored.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,N).
IPIV (output) INTEGER array, dimension (N)
The pivot indices that define the permutation matrix P; row i of the matrix was interchanged with row IPIV(i).
B (input/output) REAL array, dimension (LDB,NRHS)
On entry, the N-by-NRHS matrix of right hand side matrix B. On exit, if INFO = 0, the N-by-NRHS solution matrix X.
LDB (input) INTEGER
The leading dimension of the array B. LDB >= max(1,N).
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, U(i,i) is exactly zero. The factorization has been completed, but the factor U is exactly singular, so the
solution could not be computed.
