Subject: Automatic completion on <return>
Date: Thu, 11 Apr 2013 09:12:16 +0200 [thread overview]
Message-ID: <OFC3CCF1B0.362C13EF-ONC1257B4A.00267D76-C1257B4A.00279747@de.ibm.com> (raw)
I already have a "smart" cd-script that allows to "cd" into files:
cd with 0 parameters:
Unchanged.
cd with 1 parameters:
If the parameter is a directory name, cd into it.
If the parameter is a file name, cd into the directory containing
the file.
If the parameter is a file name that ends with .tar.gz, .tgz etc.
and a directory with the same name without the suffix exists, cd
into that (i.e. cd into extracted archives).
cd with 2 parameters:
I've forgotten what this does. That stuff does not look like my
coding style. :-)
Now I wonder how this logic could be extended to work with the autocd
option. Is it possible to augment command execution with a script. Is
there any "hook" function that is automatically called if a command
from the command line cannot be executed because it does not exist?
I've another idea how to extend this, but I'll write another message
for that.
