nohup tcpdump -t sl0 -o output.txt &
This allows tcpdump to continue running after you log out. Man nohup for
options, etc. The shell is a process leader and the tcpdump command is a
member of the shell's process group. When a process leader exits, all
other members of the group receive a HUP signal. Any process that does
does not handle this signal will be terminated. nohup merely ignores the
signal. Read Stevens APUE for more information, if interested.
