ksh and while loops
We are setting up a new server and I have to add accounts from our old server, 2000 - 3000, of them. I am trying to set up an adduser script which will read userdata from a file and then add there account.
I have set up a test server which is running Fedora 4 Core, the new server will be running this also.
The script I am using works fine on Tru64-Unix and I have messaged to, I hope so it will work on Redhat. The problem is it appears that in the:
while read -u3 line, line it isn't reading it. If I put the read -u3 line by itself and then echo $line I get the output of the file line it reads. put it back into the while statement and nothing appears to happen. No account added no errors meesages nothing.
I'm sure it has to be something simple I am doing but beats me if I can figure it out.
Here is the script and thanks for any help you can give.
#!/bin/ksh -ph
PATH=/sbin:/usr/sbin:/usr/bin:/tcb/bin
export PATH
umask 022
if [ `id -u` -ne 0 ]
then

exit 1
fi
if test ! -x /usr/sbin/useradd
then
echo 'Error, /usr/sbin/useradd missing or not executable.\n'
exit 1
