Need help with paste command using variables
How can I accomplish this? I basically want to merge two variables onto the same line. I can do it with two FILES this way:

Code:
[ngreenfield@xxxxxx tmp]$ cat /tmp/users_in.list | awk -F "," '{print $2}' | cut -c -1 > first.initial
[ngreenfield@xxxxxx tmp]$ awk -F "," '{print $1}' /tmp/users_in.list | awk '{print $1}' > last.name
[ngreenfield@xxxxxx tmp]$ paste first.initial last.name | awk '{print $1$2}'

For some reason though I can't do this with variables:

Code:
[ngreenfield@xxxxxx tmp]$ FIRSTINITIAL=`cat /tmp/users_in.list | awk -F "," '{print $2}' | cut -c -1`
[ngreenfield@xxxxxx tmp]$ LASTNAME=`awk -F "," '{print $1}' /tmp/users_in.list | awk '{print $1}'`
[ngreenfield@xxxxxx tmp]$ paste $FIRSTINITIAL $LASTNAME | awk '{print $1$2}'
paste: A: No such file or directory
[ngreenfield@pdtscope003 tmp]$

Any ideas?
