NICE(1) NICE(1) NAME nice, nohup - run a command at low priority (_s_h only) SYNOPSIS nice [ -_n_u_m_b_e_r ] command [ arguments ] nohup command [ arguments ] DESCRIPTION _N_i_c_e executes _c_o_m_m_a_n_d with low scheduling priority. If the _n_u_m_b_e_r argument is present, the priority is incremented (higher numbers mean lower priorities) by that amount up to a limit of 20. The default _n_u_m_‐ _b_e_r is 10. The super-user may run commands with priority higher than normal by using a negative priority, e.g. ‘--10’. _N_o_h_u_p executes _c_o_m_m_a_n_d immune to hangup and terminate signals from the controlling terminal. The priority is incremented by 5. _N_o_h_u_p should be invoked from the shell with ‘&’ in order to prevent it from respond‐ ing to interrupts by or stealing the input from the next person who logs in on the same terminal. FILES nohup.out standard output and standard error file under _n_o_h_u_p SEE ALSO csh(1), setpriority(2), renice(8) DIAGNOSTICS _N_i_c_e returns the exit status of the subject command. BUGS _N_i_c_e and _n_o_h_u_p are particular to _s_h(1). If you use _c_s_h(1), then com‐ mands executed with ‘‘&’’ are automatically immune to hangup signals while in the background. There is a builtin command _n_o_h_u_p which pro‐ vides immunity from terminate, but it does not redirect output to _n_o_h_u_p_._o_u_t_. _N_i_c_e is built into _c_s_h(1) with a slightly different syntax than described here. The form ‘‘nice +10’’ nices to positive nice, and ‘‘nice -10’’ can be used by the super-user to give a process more of the processor. 4th Berkeley Distribution May 8, 1986 NICE(1)
