I know this script is crummy, but I was just messing around.. how do I get sed's insert command to allow variable expansion to show the filename?
#!/bin/bash
filename=`echo $0`
/usr/bin/sed '/#include/ {
i\
the filename is `$filename`
}' $1
exit 0 (8 Replies)
When script is running you only see when some of the commands are not successfull.
Is there a way to see which command are executed and to show the substitution of variables as every line is executed ? (3 Replies)
Hi,
I am trying to do the following thing
var='date'

Above command substitutes date for and in turn runs the date command and i am getting the todays date value.

Hello All,
I don't write scripts very often, and in this case I am stumped, although it may be a bug in the version of bash I have to use (it's not my system).
I want to extract a specific string snippet from a block of text (coming from a log file) that is dependent on a bunch of other... (1 Reply)
Hello people.
Part of my script:

Unfortunatelly variable $SUBSETID in the MAPFILE declaration will not return the... (3 Replies)
Hello all. This is my first post/question on this site.
I’m a new Systems Analyst with previous experience with BASH. Although now I'm using AIX, and I’m trying to get a feel for the Korn shell (for those of you that don’t know AIX only uses the KORN shell).
I hope I put this into the correct... (10 Replies)

nec2small
NEC2(1) General Commands Manual NEC2(1)NAME
nec2, nec2small - Numerical Electromagnetics Code (Antenna Modelling Program)
SYNOPSIS
nec2 [INPUT] [OUTPUT]
nec2small [INPUT] [OUTPUT]
DESCRIPTION
nec2, is a versatile numerical Boundary Element Method (commonly called Method of Moments) antenna modelling code for the analysis of
antennas and other metal structures. It solves the integral equations for the currents induced on the structure by sources or incident
fields. The structure may either be excited by voltage sources on the structure, or by an incident plane wave of either elliptic or linear
polarisation. The structure and excitation are described in the INPUT file and the output is written to OUTPUT.
OPTIONS
Due to the age of the program, it expects input in the form of punched cards fed into a hopper. It currently does not accept any options.
If OUTPUT is omitted, output is written to stdout and if INPUT and OUTPUT are omitted then the input is taken from stdin and the output
written to stdout.
The maximum size of problem which the code can handle must be hard coded at compile time and no dynamic memory allocation is performed.
Two versions are therefore provided suitable for different sizes of problem, nec2 is compiled for a maximum of 10000 wire segments and 5000
surface patches, while nec2small is compiled for a maximum of 600 wire segments and 200 surface patches.
SEE ALSO somnec(1)
The NEC-2 code is fully documented in the report Numerical Electromagnetics Code (NEC) -- Method of Moments" by Burke and Poggio, which is
available as a printed publication in three parts covering the theory of operation, the program code and the users' manual. An updated
form of the users' manual part of this report can be found in /usr/share/doc/nec/NECdoc
BUGS
nec2 has been superseded by nec4, but this revised code has not been made available to the public, so it is possible that some bugs remain
in this version.
Also note that many variant source codes exist based on the original FORTRAN-IV listing in the report. This one is believed to be cor-
rectly working, but may still contain extra errors.
