any clues how i can get alias to accept the ARGV[0] which is the first
command line argument:
# .bashrc
alias transfer='wget "http://www.$ARGV[0]/temp/transfer.gz";';
When I run it I get:
--22:03:20-- http://www.%5C044argv%5B0%5D/temp/transfer.gz
=> `transfer.gz'
Resolving www.\044argv[0]... failed: Name or service not known.
I looked into this once or twice and no go - the way to do it is from a
simple script, say in ~/bin
<snip>From the bash manual
There is no mechanism for using arguments in the replacement
text. If
arguments are needed, a shell function should be used (see
FUNCTIONS
below).

For what you want to do, this would work:
[khuang@xxxxxxxxxxxx ~]$ chmod +x bin/transfer
[khuang@xxxxxxxxxxxx ~]$ cat ~/bin/transfer
#!/bin/bash
wget http://www.${1}/temp/transfer.gz
[khuang@xxxxxxxxxxxx ~]$ transfer google.com
--09:38:46-- http://www.google.com/temp/transfer.gz
=> `transfer.gz'
