this statement "Be sure to have /usr/bin before /usr/local/bin in your $PATH" is because, if u have any files in bin directory, /usr/local/bin will be the first place to look at instead of /usr/bin. BUT, /usr/local/bin has one more descending directory to go , therefore /usr/bin has to come before... (2 Replies)
Hi,

Hi,
I'm trying to write a bit of code that will check if a file exists and then archives the file
Im trying to use the following if statement without success..

Hi,
Am trying to execute certain commands if the condition satisfied, but i feel i am making some mistakes in the usage of if statement
here is the code

Hi All,
If i run below copy command, it works absolutely fine,
/opt/csw/bin/scp axetlxyz01:/opt/data/test/QURIES* ./input
I want to make the above line better, by adding an IF statement, want to check if there is any file exists with name QURIES*.* then i need to copy that.

my user copy large files, and it's take 10min for file to be copied to the server (/tmp/user/ files/), if in the meantime start my scheduled script, then it will copy a part of some file to server1
my idea is to check the file size twice in a short period (1-2 seconds) of time, then compare, if... (5 Replies)

In shell script, I want to transfer files continuously and make sure transfer is successful.
Please advise... how to make sure ftp transfer is successful?
Also is there any option such as sftp -b where I can pass multiple put <file name> commands to ftp
Thanks! (1 Reply)
I wish to check two conditions inside the if statement
Condition 1: The two file contents should be identical // using cmp command for this.
Condition 2: The two filenames should NOT be the same.
This is what i did in vain.

sla_lin_berr.f
sla_lin_berr.f(3) LAPACK sla_lin_berr.f(3)NAME
sla_lin_berr.f -
SYNOPSIS
Functions/Subroutines
subroutine sla_lin_berr (N, NZ, NRHS, RES, AYB, BERR)
SLA_LIN_BERR computes a component-wise relative backward error.
Function/Subroutine Documentation
subroutine sla_lin_berr (integerN, integerNZ, integerNRHS, real, dimension( n, nrhs )RES, real, dimension( n, nrhs )AYB, real, dimension( nrhs
)BERR)
SLA_LIN_BERR computes a component-wise relative backward error.
Purpose:
SLA_LIN_BERR computes componentwise relative backward error from
the formula
max(i) ( abs(R(i)) / ( abs(op(A_s))*abs(Y) + abs(B_s) )(i) )
where abs(Z) is the componentwise absolute value of the matrix
or vector Z.
Parameters:
N
N is INTEGER
The number of linear equations, i.e., the order of the
matrix A. N >= 0.
NZ
NZ is INTEGER
We add (NZ+1)*SLAMCH( 'Safe minimum' ) to R(i) in the numerator to
guard against spuriously zero residuals. Default value is N.
NRHS
NRHS is INTEGER
The number of right hand sides, i.e., the number of columns
of the matrices AYB, RES, and BERR. NRHS >= 0.
RES
RES is REAL array, dimension (N,NRHS)
The residual matrix, i.e., the matrix R in the relative backward
error formula above.
AYB
AYB is REAL array, dimension (N, NRHS)
The denominator in the relative backward error formula above, i.e.,
the matrix abs(op(A_s))*abs(Y) + abs(B_s). The matrices A, Y, and B
are from iterative refinement (see sla_gerfsx_extended.f).
BERR
BERR is REAL array, dimension (NRHS)
The componentwise relative backward error from the formula above.
