Unix scrpting : Append to a file

linux_newbee · 06-08-2006, 08:17 AM

I am trying to write a Unix script which does the following:

Append the

Code:

alias myserver='/usr/bin/myserver :$SOME_USERID -name  $SOME_USERNAME'

to the end of a particular file.

Can anyone help me with doing this ?

I tried the following

Code:

 echo "alias myserver='/usr/bin/myserver :$SOME_USERID -name $SOME_USERNAME'" >> .bashrc

But i am getting the following

invalid command name "echo"
while executing
"echo "alias

Why is this happening ?
Any other way to do the appending ?

Thanks in advance

You've apparently defined an alias for echo. To display all your aliases:

alias

To remove an alias (also remember to remove it from any scripts executed at login):

unalias echo

The left slash prevents an alias expansion for the following command.

Code:

$ \echo "whatever..."

will execute the internal bash echo, not an alias.

No i am not trying to create an alias for echo. I am trying to create an alias for "myserver"

You're trying to do this right?

Code:

$ cat > file
test <CTRL+D>
$ echo "alias myserver='/usr/bin/myserver :\$SOME_USERID -name \$SOME_USERNAME'" >> file
$ cat file
test
alias myserver='/usr/bin/myserver :$SOME_USERID -name $SOME_USERNAME'

Yes.... this is what I am trying to do. This "file" is a script file. So i try to execute the file after i put the echo commands. but it gives me the error....
" invalid command name "echo" while executing "

Yes, we understand this.
What we are talking, is maybe, there is, for some reason, an incorrect alias to echo.

try to put, as macemoneta pointed, "unalias echo", right before the echo "alias=whatever" in your script.
