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...
The use of cat with awk and in a while loop is redundant.
True.
However, I find that seeing the name of the file at the beginning
of a pipe-line, in general, is convenient for legibility and comprehension.
That is, no searching to the end of a lenghthy pipe or awk script to see what the input file is.

Right, but it's not a bad habit to make known how to avoid cat to make the code more efficient (and faster).
