Using shortcuts/alias inside a Linux Bash Command


Hi,
I know that using alias I can run a whole command with a shortcut. But my requirement is to use parts of a long command and in between I have to pass some user defined values.
E.g. Suppose I have to routinely copy a directory to another remote directory on a remote machine.
The remote machine name is quite long as well as the directory path to which I want to copy the files into.
So the command to do scp would look like this
$ scp -r ./<source_directory> pratap@remote.machine.name:~/dest_dir/

Now I want to do some sort of aliasing (say "ecp") so that I just need to pass the source_directory name and the ecp command and do my job.
Can you give me any suggestion on how can I do this in a convenient way?
Thanks,
pratap

You need to do it with a function, or just create a tiny executable and put it in your $PATH

yes you will need a function...

you can through it in your .profile, or if you use bash .bashrc.

ecp () {
scp -r $1 pratap@remote.machine.name:~/dest_dir
}

ecp /path/to/dir

you can get fancy too, say you want to copy to dest_dir and and append the date to the directory you are copying over... you can do it like so

ecp () {
scp -r $1 pratap@remote.machine.name:~/dest_dir/${1}.`date +%m-%d-%Y`
}

all up to you.
