bash variables

Hi,

I want to set a value equal to my ip address in my .bashrc file so I can do the following:

scp file1 me@$MYHOMEIPADDRESS:~/

from my bash prompt I know I can do set MYHOMEIP = xxx.xxx.xxx.xxx, and I can do echo $MYHOMEIP to get it to show me my address but when I try to use the variable in the scp command it doesn't work.

please help!

You are using different variables - try:
scp file1 me@$MYHOMEIP:~/

I did have the same variable name, I was just sloppy...

here is what I do:

set WIFI = 192.168.0.1

(to test) ping $WIFI - works no problem

scp test.text $WIFI:~/ - doesn't work (i have the same user name on both machines so I don't need to put jim@$WIFI)

Bad : modifier in $ (~).

that's my error message.

anybody know how to get around this?

just omit the ~/ then ...
scp will chuck copied stuff in your home by default.

Cheers,
Tink

You could also stop the variable being expanded by using "${WIFI}" instead of "$WIFI"
