Append strings with filler spaces
Hi
I am looping through the contents of a file as follows
cat file |while read inrec
do
echo $inrec >> $TMP
done
(obviously this isn't all i am doing as it would be pointless but for the sake of the problem this is the important bit)
The file has fields which are separated by several spaces as follows
1 2 3 4 etc.
When i echo $inrec to screen i see the output as
1 2 3 4 (i.e each bunch of spaces is being treated as one)
This is fine for what i wanted to do.
But now i want to append a number (say 99) onto the end of each $inrec when sending it to the TMP file. So i tried this
echo $inrec$num
But the output shows this
992 3 4
WHen i put speech marks around the variables the output showed
1 2 3 499
but i only need one space as before.
Any ideas.

ECHO(1) BSD General Commands Manual ECHO(1)
NAME
echo -- write arguments to the standard output
SYNOPSIS
echo [-n] [string ...]
DESCRIPTION
The echo utility writes any specified operands, separated by single blank (' ') characters and followed by a newline ('
') character, to the
standard output.
The following option is available:
-n Do not print the trailing newline character. This may also be achieved by appending 'c' to the end of the string, as is done by iBCS2
compatible systems. Note that this option as well as the effect of 'c' are implementation-defined in IEEE Std 1003.1-2001
(``POSIX.1'') as amended by Cor. 1-2002. Applications aiming for maximum portability are strongly encouraged to use printf(1) to sup-
press the newline character.
Some shells may provide a builtin echo command which is similar or identical to this utility. Most notably, the builtin echo in sh(1) does
not accept the -n option. Consult the builtin(1) manual page.
EXIT STATUS
The echo utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
builtin(1), csh(1), printf(1), sh(1)
STANDARDS
The echo utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002.
