Reading multiple values from multiple lines and columns and setting them to unique variables.
Hello,
I would like to ask for help with csh script.
An example of an input in .txt file is below, the number of lines varies from file to file and I have 2 or 3 columns with values. I would like to read all the values (probably one by one) and set them to independent unique variables that can be used later for mathematical operations or "cat" outputs. Is it possible to do it in C-shell? I would not like to change the shell because I want to add this part to my "value extraction" script which I made.
Dear all,
I am novice in C+= programing. I would like to seek help in one of the progra. Here it is, I have txt file which has the data as following order
varA varB
-21 0
-21.2 3, 4, 5, 6
-21.4 45, 65, 87, 98, 98
-22.0 345677, 349887, 98766, 877654, 987543
-23.0 76549,... (17 Replies)

resize
RESIZE(1) General Commands Manual RESIZE(1)NAME
resize - set environment and terminal settings to current xterm window size
SYNOPSIS
resize [ -u | -c ] [ -s [ row col ] ]
DESCRIPTION
Resize prints a shell command for setting the appropriate environment variables to indicate the current size of xterm window from which the
command is run. For this output to take effect, resize must either be evaluated as part of the command line (usually done with a shell
alias or function) or else redirected to a file which can then be read in. From the C shell (usually known as /bin/csh), the following
alias could be defined in the user's .cshrc:
% alias rs 'set noglob; eval `resize`'
After resizing the window, the user would type:
% rs
Users of versions of the Bourne shell (usually known as /bin/sh) that don't have command functions will need to send the output to a tempo-
rary file and then read it back in with the "." command:
$ resize > /tmp/out
$ . /tmp/out
Resize determines the user's current shell by first checking if $SHELL is set, and using that. Otherwise it determines the user's shell by
looking in the password file. Generally Bourne-shell variants (including ksh) do not modify $SHELL, so it is possible for resize to be
confused if one runs resize from a Bourne shell spawned from a C shell.
OPTIONS
The following options may be used with resize:
-u This option indicates that Bourne shell commands should be generated even if the user's current shell isn't /bin/sh.
-c This option indicates that C shell commands should be generated even if the user's current shell isn't /bin/csh.
-s [rows columns]
This option indicates that Sun console escape sequences will be used instead of the VT100-style xterm escape codes. If rows and
columns are given, resize will ask the xterm to resize itself. However, the window manager may choose to disallow the change.
Note that the Sun console escape sequences are recognized by XFree86 xterm and by dtterm. The resize program may be installed as sunsize,
which causes makes it assume the -s option.
The rows and columns arguments must appear last; though they are normally associated with the -s option, they are parsed separately.
FILES
/etc/termcap for the base termcap entry to modify.
~/.cshrc user's alias for the command.
ENVIRONMENT
TERM set to "xterm" if not already set.
TERMCAP variable set on systems using termcap
COLUMNS, LINES variables set on systems using terminfo
