Aliases are expanded early on, during input, and so you can't use an alias within the same chunk of shell code as where it's defined. This isn't going to change; you need to find a workaround. The standard approach is to use functions in such chunks of code. Aliases tend to be regarded as largely an interactive feature. This ought to be documented somewhere, if it isn't. -- Peter Stephenson <pws@csr.com> Software Engineer CSR PLC, Churchill House, Cambridge Business Park, Cowley Road Cambridge, CB4 0WZ, UK Tel: +44 (0)1223 692070 ^ permalink raw reply [flat|nested] 2+ messages in thread
