Insert special character in text file

Leo The Cat — Tue, 20 Jan 2009 16:05:11 GMT

Hi

I'd like to do something like that:

echo $1$2

But between $1 and $2 I'd like to insert a TAB character (ascii 9).

How to do this small trick ?

Bests Regards

You could just use a Tab character, too. The
quotation marks are the critical things.

Among uncounted other possibilities:

bash$ a=A
bash$ b=B
bash$ echo "$a $b"
A B
bash$ echo $a' '$b
A B

(Due to Forum limitations, you'll need to
imagine that there are actual Tab characters
in there.)

Using a Tab character may be unwise, however,
if you're actually sending it to a terminal
(or emulator). What you see on a terminal
depends on the terminal's tab settings, over
which you may have little or no control. The
result can be very ugly output.

I think Shoghi Martinez G. solution works 100% if "-e" will be used

echo -e "$1\t$2"
