Hello,
Can you explain why in the first 2 commands the awk does not print anything? Is it looking of a specific format ?
Thanks.
$ echo 12a3 | awk '($1>=2) {print $1}' # prints nothing
$ echo 123a | awk '($1>=2) {print $1}' # prints nothing
$ echo a123 | awk '($1>=2) {print $1}'

Dear Group,
I want to prepare an ELF file which can be downloaded dynamically to any address in the moemory and executes as a new task/thread/process.
1) for this what are all the compileation, linker options while building the ELF file?
2) which parts of ELF file has to modified while... (1 Reply)
how can i specify more than 1 consition in the following AWK statament??
i.e. if $2 is ABCD and $3 is MNOP and $4 is KLPM
similarly for OR
#!/bin/ksh
awk -F '' ' $2 == "ABCD" { print $2, $3;}' file.xml (2 Replies)
Hi Everyone,
# cat 1
1;2;3;4;5;6
1;2;3;4;5;
# awk -F ";" '$5 == "5"' 1
1;2;3;4;5;6
1;2;3;4;5;
but the output is should be just "1;2;3;4;5;6" means 1st condition: $5 is 5; 2nd condition: $6 is not empty, please advice. Thanks (2 Replies)
Hi there, here is my command
ssh host.local "/path/to/my/perscript/hostconfig.pl -s $HOST -d |awk '{if (\$4 > 120)print \"My error message\";exit}{s=0; for (i=1; i<=NF; i++) s++; if(s == 13) print \$3}'"
The problem is if conditional 1 is met (i.e $4 > 120), i don't see "My error message", the... (5 Replies)

I'm having a problem pulling UID's from data. The data outputs a user's UID in one of three ways:

bamg(1rheolef) rheolef-6.1 bamg(1rheolef)NAME
bamg - bidimensional anisotropic mesh generator
SYNOPSIS
bamg options -g input[.bamgcad] -o ouput[.bamg]
EXAMPLE
bamg -g toto.bamgcad -o toto.bamg
OUTLINE OF THE COMMANDS
This software can
create a mesh from a geometry
adapt a mesh from a background mesh using a metric or solution file
do smoothing
to make quadrilaterals and to split internal edge with 2 boundary vertices in an existing mesh (in this case the metric is use to
change the definition of the element's quality).
construct
just a metric file, if you have an other mesher
do the P1 interpolation
of the solution on another mesh:
CREATE A MESH FROM A GEOMETRY
input file with -g filename (file type DB mesh).
output file arguments -oxxxx filename where xxxx is the type of output file (see below for more details).
smoothing, quad, utility and other parameters.
In addition, metric specication may be prescribed with the help of -M filename argument (file type Metric). All the options are
described below.
ADAPT A MESH FROM A BACKGROUND MESH USING A METRIC OR SOLUTION FILE
input files -b filename where the suffixe of the file define the type of the file `.amdba', `.am_fmt', `.am', `.ftq', `.nopo' and other-
wise the file is a BD mesh file.
input `-M filename' (file type Metric) or -MBB filename or -Mbb filename (solution file type BB or bb).
metric control parameters, -err val, -errg val,....
output file arguments reqired
interpolation, smoothing, quad,
utility parameter, and other parameter do smoothing, to make quadrilaterals: and to split internal edge with 2 boundary vertices in
an existing mesh (in this case the metric is use to change the definition of the element's quality).
input files -r filename(file type DB mesh).
-M filename
(file type Metric).
output file -o filename (file type DB mesh).
some other parameter:
@table @code
-thetaquad val:
to create quad with 2 triangles
-2: to create the submesh with mesh size h = h/2
-2q: to split all triangles in 3 quad. and to split all quad. in 4 quad.
-NbSmooth ival:
to change the number of smoothing iteration (3 by default if the metric eld is set with arguments : -M or -Mbb, 0 otherwise.
... @end table construct just a metric file, if you have an other mesher:
input files -r filename (file type DB mesh).
--Mbb filename
or -MBB filename
+ all the arguments
of the metric construction
output file -oM filename (file type Metric). do the P1 interpolation of the solution on another mesh:
input files -r filename (file type DB mesh).
--rBB filename
or -rbb filename
output file -wBB filename or -wbb filename
METRIC COMPUTATIOB OPTIONS
These options are relevant when computing a metric from a scalar field provided in a .bb file. Notice that, when providing a tensor metric
in the .bb file, the metric computation is not performed and these options are not relevent.
-RelError
compute the metric with a relative error. This is the default.
-CutOff float
the cut-off value used for the relative error criteria. Default value is 1e-5.
-AbsError
compute the metric with a relative error
