You are badly using features of bash. Write a script which will do things for you, or use any other language/shell.

Please, accept this response as a suggestion.

command_not_found_handle is designed to do other things than you are expecting.

Hi Chet,

sorry, i thought you talk about the bash code.
I didn't want to show my own usecase but now i have to ;-):
I have a File class and can construct a File "object" for example:
File anObjectName /etc/passwd
and then i can do
e.g. anObjectName.getInode (this already works with
command_not_found_handle() )
But if i do a:
File /etc/passwd /etc/passwd
and then
/etc/passwd.getInode (i think it would be nice if the normal files in a
filesystem could be treated like objects)
then there is nothing that triggers the command_not_found_handle() to split
"object" and method...
So at the moment slashes are forbidden in object names in my fun project.

Now you know why your bash example for ckexec() isn't a solution for me.

bye
Andreas

Hi Chet,

I have no idea if there is "enough" demand, but i think there will be
some
ideas to use this feature...
I still think it is a question of consistency to be able to handle a "No
such file or directory event", if i can do this with a "command not found
event" (independent of the command_not_found_handle history).

You say you can easily test whether or not if the file in the pathname
exists.

That is not what I said.  I said that you, the script writer, can check
whether or not a filename containing a slash is executable before
attempting to execute it.  Maybe a function something like this (untested):

ckexec()
{
         case "$1" in
         */*)    ;;
         *)      "$@"  ; return $? ;;
         esac

         if [ -x "$1" ]; then
                 "$@"
         else
                 other-prog "$@"
         fi
}
