Using a bash shell cat -v only seems to work on files, the example given above with echo $variable | cat -v doesn't produce any output.
Not true, though I would prefer:
Code:
echo "${variable}" | cat -v

It certainly does, or at least should.
Code:
$ cat -v /tmp/t
bell^G
$ od -c /tmp/t
0000000   b   e   l   l 007  \n
0000006
$ variable=$(</tmp/t)
$ echo $variable | cat -v
bell^G
$

Please provide some clues about your tests.
