i have to search direcotry with a Min or Max size and but with a standard find.... it gives me the size of the i-node of the directory.
A friend told me to use awk/sed command to search directories.
he also gave me this command:

hello,
I have this in a file
server_name=DB1
hostname=db1
I want to change hostname value to `hostname`. Any idea?
and server_name value to toUPPER (`hostname`). Any idea?

I have a text file with about 790 lines, at the end of many of the lines there is the text string 'f4' I want this text to be 'f2' What is the best way to do this? is it sed or awk? or something else? how? Also, there is maybe fifty occasions where f4 appears near the begining of the line that I... (2 Replies)
Hi,
I have to write a script that goes through every *.cpp file in the current directory and if any file has #includes of non-system header files (those with double quotes around them), then I need to print out those header files within the quotes. I've figured out how to run a for loop and find... (4 Replies)
hi there!
i have a question that i hope someone may be able to help me with.
i am using the 'paste' function to concatenate to files together.
$ paste A B
output:

I have a string that I need to remove data that is not within <>. For example:
this is a <test> of removing <text> outside brackets
output should be:

I can use either of the two outputs but so far I have not had much luck removing all of the other text. The... (15 Replies)
Hi all,
I'm pretty new to Unix (Sun) scripting, and wanted to try doing what many would probably believe is pretty easy. I tried searching the forums and only found bits and pieces of things I wanted to do below, but after many tries had a very hard time piecing it together.
Would anyone... (1 Reply)

gensurf
GENSURF(1) General Commands Manual GENSURF(1)NAME
gensurf - generate a RADIANCE or Wavefront description of a curved surface
SYNOPSIS
gensurf mat name 'x(s,t)' 'y(s,t)' 'z(s,t)' m n [ -e expr ][ -f file ][ -s ][ -o ]
gensurf mat name 'x(s,t)' 'y(s,t)' dfile m n [ -e expr ][ -f file ][ -s ][ -o ]
gensurf mat name dfile dfile dfile m n [ -s ][ -o ]
DESCRIPTION
Gensurf produces either a RADIANCE scene description or a Wavefront .OBJ file of a functional surface defined by the parametric equations
x(s,t), y(s,t), and z(s,t). The surface normal is defined by the right hand rule as applied to (s,t). S will vary from 0 to 1 in steps of
1/m, and t will vary from 0 to 1 in steps of 1/n. The surface will be composed of 2*m*n or fewer triangles and quadrilaterals. The
expressions are of the same type used in RADIANCE function files. Auxiliary expressions and/or files may be specified in any number of -e
and -f options. The -s option adds smoothing (surface normal interpolation) to the surface. The -o option produces a Wavefront .OBJ file
rather than a RADIANCE scene description. This is most useful as input to the obj2mesh(1) program for producing a compiled mesh. A single
"usemtl" statement will appear at the beginning of the .OBJ output, echoing the modifier given on the command line.
Rough holes may be cut in the mesh by defining a valid(s,t) function. Where this function is positive, polygon vertices will be produced.
Where it is negative, no geometry will be output. Surface normal interpolation will ignore any invalid vertices.
The second invocation form reads z data values from the file dfile. This file must give either m*n or (m+1)*(n+1) floating point z values.
If m*n values are given, then the values correspond to the centroid of each quadrilateral region. If (m+1)*(n+1) values are given, then
the values correspond to the vertices of each quadrilateral region. The ordering of the data in the file is such that the s values are
changing faster than the t values. If a minus ('-') is given for dfile, then the values are read from the standard input.
The third invocation form is used to read coordinate triplets from a file or the standard input. The three dfile arguments must all be the
same, and the corresponding file must contain three floating point values for each point location. The ordering and other details are the
same as those described for z value files above.
EXAMPLE
To generate a tesselated sphere:
gensurf crystal ball 'sin(PI*s)*cos(2*PI*t)' 'cos(PI*s)' 'sin(PI*s)*sin(2*PI*t)' 7 10
To generate a 10x20 smoothed height field from 12 recorded vertex z values:
gensurf dirt ground '10*s' '20*t' height.dat 2 3 -s

BUGS
The smoothing operation requires that functions be defined beyond the [0,1] boundaries of s and t.
