I am new to unix....
I require to append 100 spaces(fillers) to header(first line) and 100 space to trailer(last line).
the data in the middle not to be changed.
i do not want variable length record file turned into a fixed width record file. i just need to append 100 fillers in the first line and 100 fillers in last line
sample file:
HODA(need to add 100 fillers(spaces) here)
D0000000000000000000000000000000000
D0000000000000000000000000000000000
T000012(need to add 100 fillers(spaces) here)
Well, just some questions then:
Why would you need to make the header and trailer ONLY 106 characters in length?
Usually, this is because an old mainframe type program is reading the file with a fixed record size. For fun, just check the size of your "D" records and see if they aren't 106 characters wide.
At any rate, here's a ksh solution:
Here's an awk solution:
Notice the use of the printf() in both solutions.
I also like this syntax for printf:
... where you can pass the width in as an argument to printf.
It's a smidge easier to modify later on...

fmtcheck
FMTCHECK(3) BSD Library Functions Manual FMTCHECK(3)NAME
fmtcheck -- sanitizes user-supplied printf(3)-style format string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
const char *
fmtcheck(const char *fmt_suspect, const char *fmt_default);
DESCRIPTION
The fmtcheck function scans fmt_suspect and fmt_default to determine if fmt_suspect will consume the same argument types as fmt_default and
to ensure that fmt_suspect is a valid format string.
The printf(3) family of functions can not verify the types of arguments that they are passed at run-time. In some cases, like catgets(3), it
is useful or necessary to use a user-supplied format string with no guarantee that the format string matches the specified parameters.
The fmtcheck function was designed to be used in these cases, as in:
printf(fmtcheck(user_format, standard_format), arg1, arg2);
In the check, field widths, fillers, precisions, etc. are ignored (unless the field width or precision is an asterisk '*' instead of a digit
string). Also, any text other than the format specifiers is completely ignored.
Note that the formats may be quite different as long as they accept the same parameters. For example, "%p %o %30s %#llx %-10.*e %n" is com-
patible with "This number %lu %d%% and string %s has %qd numbers and %.*g floats (%n)." However, "%o" is not equivalent to "%lx" because the
first requires an integer and the second requires a long.
RETURN VALUES
If fmt_suspect is a valid format and consumes the same argument types as fmt_default, then the fmtcheck function will return fmt_suspect.
Otherwise, it will return fmt_default.
