How to read contents of a file into variable :(
My file is in this format :
username : student information : default shell : student ID
Eg :
joeb:Joe Bennett:/bin/csh:1234
jerryd:Jerry Daniels:/bin/csh:2345
deaverm: Deaver Michelle:/bin/bash:4356
joseyg:Josey Guerra:/bin/bash:8767
michaelh:Michael Hall:/bin/ksh:1547
I have to read the contents of each field for creating user accounts.
I have to use each field in my useradd command for creating user accounts.
Later i even have to create password based on username and student id..
All i need is an idea.
am struck at retrieving the values from file.
Any help would be greatly appreciated .
Thank you ..

RESIZE(1) General Commands Manual RESIZE(1)
NAME
resize - set TERMCAP and terminal settings to current xterm window size
SYNOPSIS
resize [ -u | -c ] [ -s [ row col ] ]
DESCRIPTION
Resize prints a shell command for setting the TERM and TERMCAP 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 follow-
ing 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 the read it back in with the ``.'' command:
$ resize > /tmp/out
$ . /tmp/out
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 special xterm escape code. If rows and columns
are given, resize will ask the xterm to resize itself. However, the window manager may choose to disallow the change.
FILES
/etc/termcap for the base termcap entry to modify.
~/.cshrc user's alias for the command.

The -u or -c must appear to the left of -s if both are specified.
