Another command that might be available and also works quite well for this is 'blkid'. It's part of the e2fsprogs package. Examples of it's usage:
Look up data on /dev/sda1:
topher@crucible:~$ sudo blkid /dev/sda1
/dev/sda1: UUID="727cac18-044b-4504-87f1-a5aefa774bda" TYPE="ext3"
Show UUID data for all partitions:
topher@crucible:~$ sudo blkid
/dev/sda1: UUID="727cac18-044b-4504-87f1-a5aefa774bda" TYPE="ext3"
/dev/sdb: UUID="467c4aa9-963d-4467-8cd0-d58caaacaff4" TYPE="ext3"
Show UUID data for all partitions in easier to read format:
(Note: in newer releases, blkid -L has a different meaning, and blkid -o list should be used instead)
topher@crucible:~$ sudo blkid -L
device fs_type label mount point UUID
-------------------------------------------------------------------------------
/dev/sda1 ext3 / 727cac18-044b-4504-87f1-a5aefa774bda
/dev/sdc ext3 /home 467c4aa9-963d-4467-8cd0-d58caaacaff4
Show just the UUID for /dev/sda1 and nothing else:
topher@crucible:~$ sudo blkid -s UUID -o value /dev/sda1
727cac18-044b-4504-87f1-a5aefa774bda
If you're using Bash, you can run disown -h job
disown
disown [-ar] [-h] [jobspec ...]
Without options, each jobspec is removed from the table of active jobs.
If the -h option is given, the job
is not removed from the table, but is
marked so that SIGHUP is not sent to
the job if the shell receives a
SIGHUP. If jobspec is not present, and
neither the -a nor -r option is
supplied, the current job is used. If
no jobspec is supplied, the -a
option means to remove or mark all
jobs; the -r option without a
jobspec argument restricts operation
to running jobs.

ifconfig is usually in /sbin. Depending on what system you're running this mightn't be on your path (in particular, RedHat systems don't include this on the default path)
Try:
If it works then that's the issue, and you should change your path via your .bashrc (or whatever shell you're using).
