Replace col 23 - 26 with new value, non delimited file
hello,
i have a undelimited file which contains 229 byte records. i want to change column 23 - 26 with a new value and also change the sign of the data in colulmn 30 - 70. i've tried SED for the first change, but nothing happens:
heres an example of my record -but it doesn't display the whole 229 bytes - not sure why
this is what i want
make the code changes and keep the full record of 229 bytes thanks!
can you help with both requests - thanks!

Hello,
I have a 1.6 GB file that I would like to modify by matching some ids in col1 with the ids in col 1 of file2.txt and save the results into a 3rd file.
For example:
File 1 has 1411 rows, I ignore how many columns it has (thousands)
File 2 has 311 rows, 1 column
Would like to... (7 Replies)
I have file with multiple columns. Column values for a record may be same.
Now i have to replace a column value(this can be same for the other columns) with new value.

Hello,
I want to Replace/Remove ^M and the new line that follows it in a delimited file.
So far I have tried following and nothing seems to work for me .
Tr –d ‘\r\n’ < old.dat > new.dat -removes all the linefeed, not just the ones after a ^M.

I have a file like this.
It is tab delimited.
Unfortunately, the missing data was filled in with a period "." (see the leading lines 1-5 columns)
I want to substitute the periods for misisng data with an integer "-999".
however, I do not want the global replace to change the other periods seen... (7 Replies)

discgrp
discgrp(5gv) Geometry Project Programs discgrp(5gv)NAME
discrete group file formats
SYNOPSIS
An ascii file representation of a discrete geometric group.
SUMMARY
This file format applies to a wide variety of groups encountered in topology and geometry. At the beginning of the file is the string DIS-
CGRP, in conformity with other OOGL file formats (see oogl(5)). The remainder of the file is a series of parenthesized expressions.
The file format is based on an expandable set of key markers and values. A typical entry would be
(group borromean )
where parentheses enclose the expression. The string 'group' is called the key marker. The remaining text contains a value, in this case
a character string which is the name of the group. Key markers currently recognized and their values include:
group A name for this group.
comment An arbitrary comment [maximum length 256 bytes]
[must be enclosed in double quotes]
attribute One of a several keyword identifiers including:
euclidean is a euclidean group
hyperbolic is a hyperbolic group
spherical is a spherical group
transposed the matrices are transposed
finite this is a finite group
model In the case that 'hyperbolic' is an attribute, and the dimension is
three, this keyword sets the model that is
expected for reading subsequent isometries, i.e., expects elements of
SL(2,C) if the model is upperhalfspace or conformalball and O(3,1,R) if it is
projective.
projective default
upperhalfspace
conformalball [not currently implemented]
display These values set characteristics of the the display of the discrete
group.
centercam keeps the camera centered in central dirichlet domain.
zcull removes tiles which lie behind the camera.
showcam if centercam is set, displays camgeom, if provided (see below).
dimn The dimension of the space.
ngens Number of generators.
gens List of generators.
nels Number of group elements.
els List of group elements.
wafile Word acceptor file (in DEAGL format version 2.2)
camgeom An OOGL-format geometry description to represent the observer.
geom An OOGL-format geometry description. Will replace the default Dirichlet domain computation.
String-matching of key markers and attribute values is case-insensitive.
Currently all matrices must be 4x4 real matrices. Hence the only valid dimensions are 2,3, or 4. The typical case is dimension 3 where
there are projective models for hyperbolic, euclidean, and spherical geometry. Dimension 2 groups should leave the z-coordinate unchanged.
Matrices are considered transposed if they are considered to act on column vectors as in: M.v = v'. This is the usual mathematical conven-
tion convention. So, if you use this convention you must mark your matrices as being transposed.
Group elements are specified by an optional character string followed by a list of 16 real numbers. For the case of generators, the char-
acter string represents the name of that generator. Its main use is with the automatic group software: the name used here should match that
of the generator in the word acceptor file. It should, for example, be a single character for the software to work reliably. For composite
elements, the string is the word in the generators which describes this group element.
OOGL libraries expect discrete group files to use the '.dgp' suffix.
A file which describes the group of the three dimensional torus follows:
DISCGRP
(group 3torus )
(comment " This is a test of the new discrete group library. " )
(attribute Euclidean )
(display centercam )
(enumdepth 3 ) # look at all words of length 3 or less in generators
(enumdist 10.0 ) # and which don't move the origin more than 10.0

Example group files are to be found in the OOGL release in ${GEOM}/data/groups, where e.g., GEOM = /u/gcg/ngrap. See also discgrp(3) and
automata(1).

BUGS
For dimension 2, the code should read and write 3 x 3 matrices.
