Hi,
does anybody knows how to manage, that the filenames are assigned to a variable in a loop afer getting them with set command in a ksh, like:
set B*.txt
i=1
c=$#
x=$((c+1))
echo "$x"
while ] ; do
_ftpfile$i="$"$i
echo "$_ftpfile$i"
i=$((i+1))
done
The first echo returns,... (2 Replies)
Hi,
I'm using a for loop reading from an input file that contains files, whose path includes a variable name.
But the for loop doesn't expand the variable and therefore can't find the file.
Here's an example:

I'm wondering if any of you could lend an assist with a small problem.

Hi,
I've got a text file with hundreds of lines I need to upload to an API via curl, one by one.
The text file is like:

Hi All,
I have to insert 2 values to a text file in specific places. I have been able to extract each variable value via a script but am not able to send these variable values to the text file.
Pasted is the script for extracting the variable values:

When I create a newfile, I am using the filename as a variable to create the new filename. When I ouput it, the filename contains the file extension in the middle of the file

My initial approach was to strip it out, now I... (2 Replies)

s_curl
s_curl(3rheolef) rheolef-6.1 s_curl(3rheolef)NAME
s_curl -- curl-like operator for the Stokes stream function computation
SYNOPSIS
form(const space M, const space& V, "s_curl");
DESCRIPTION
Assembly the form associated to the s_curl operator on a finite element space V:
/
|
b(xi,u) = | u.s_curl(xi) dx
|
/ Omega
The M and V space may be a either P1 or P2 finite element space. The M space is scalar-valued while the V is vector-valued. See also
form(2) and space(2).
For cartesian coordinate systems, this form coincide with the usual "curl" one (see curl(3)). In the axisymmetric case:
/
| (d xi d xi )
b(xi,u) = | (---- ur - ---- uz) r dr dz
| (d z d r )
/ Omega
The b form is denoted as "s_curl", for Stokes stream function computation (see s_grad_grad(3)) as it is closely related to the "curl" oper-
ator (see curl(3)), but differs by the r and 1/r factors, as:
( d (r xi) d xi )
curl(xi) = ( (1/r) -------- ; - -----)
( d r d z )
while
( d xi d xi )
s_curl(xi) = ( ---- ; - ---- )
( d r d z )
Notice also that the differentiation is performed on the xi variable here: b(xi,u)=(s_curl(xi),u) while the "curl" form brings the differ-
entiation on the u vector-valued variable: (curl(u),xi), i.e. a transpose formulation.
ORIENTATION AND SIGN FIX
The (r,theta,z) coordinate system has positive orientation, thus (z,r,theta) and (z,r) are positive also. But (r,z,theta) and (r,z) are
negative : the sign of s_curl is then inverted to obtain the same result as if (z,r) was used.
EXAMPLE
The following piece of code build the form associated to the P1 approximation:
geo g("square");
space M(g, "P1");
space V(g, "P1", "vector");
form a(M, V, "s_curl");
