Get the last value in the input stream

Hello Everyone,
The situation is:
Code:
$ alias rm="sh abc.sh"

Code:
#abc.sh:
read input
echo "The input was: " $input

Code:
$ rm xyz.txt

should return
"The input was: xyz.txt"

Here, I want the alias "rm" to execute the file "abc.sh", where "abc.sh" should take "xyz.txt" as "input" and echo the desired information(without using sed or awk).
Kind Regards,
Qasim

Hi.

The read command reads from standard input. You are passing it in this case as a parameter, so you should access it using $1

i.e.

Code:
#abc.sh:
echo "The input was: " $1

If you really want to use read, then:
Code:
echo $1 | read input
echo "The input was: " $input

But that's kinda pointless here, I think.
