bash: How do I create function from variable?

Question

How do I create a function named from the contents a variable? I want to write a template script that defines a function named after the script’s own file name. Something like this (which of course doesn't work):

#!/bin/bash bname="$(basename $0)" # filename of the script itself  someprefix_${bname}() { # function's name created from $bname variable     echo test } 

So if the script's filename is foo.sh, then it should define a function named someprefix_foo that will echo "test".

Answer 1

You can use eval:

eval "someprefix_${bname}() { echo test; }" 

Bash even allows "."s in function names :)

Answer 2

Indeed, it is instructive that the aforementioned construction derails the possibility of having embedded quotation marks there within and is thus potentially bugulant. However, the following construction does proffer similar functionality whilst not having the constraints of the former answer.

For your review:

source /dev/stdin <<EOF function someprefix_${bname}() {      echo "test"; }; EOF
