why "cd ~username" OK but "cd ~$USERNAME" not OK ?

[nigelmcguinness]

I want to change to the home directory of user1

cd ~user1

that works fine but if I use a variable for username

USERNAME=user1
cd ~${USERNAME}[\code]

I get error message:

[b]ksh: ~user1: not found[/b]

 

[vti]

you could try

USERNAME=user1
export USERNAME
cd ~${USERNAME}

I hope this helps.

The export didn't make any difference - it still doesn't work?

oracle@nuh105-/ora/admin/bin> export ME

What do you see if you write "whoami"

 

[grega]

Very strange ... it all works fine for me in ksh!

Unixadmin: I get -

oracle@nuh105-/ora/admin/bin> whoami
oracle
oracle@nuh105-/ora/admin/bin> who am i
c950849    ttyp5        Apr 20 09:22

 

[vti]

Do you logon first as c950849 and is your second logon oracle?
And i think if you write ;
ME=`whoami | cut -f1 -d" "`
export ME
echo $ME

you will get oracle.Is this what you want?
