- The _jjjj_llll_iiii_mmmm_iiii_tttt command displays and changes limits on resource usage for a
- job. The current and maximum (hard) limits are set when a job starts
- from values that are contained in the user limits database (ULDB)
- information for the user. You can raise and lower your current limits
- within the range not to exceed your maximum limit. You can irrevocably
- lower your maximum limit. You must have the CAP_PROC_MGT capability to
- raise your maximum limit. Limit enforcement always occurs at the current
- limit regardless of your maximum limit value. See the capabilities(4)
- man page for more information on the capability mechanism that provides
- fine grained control over the privileges of a process.
-
- The _jjjj_llll_iiii_mmmm_iiii_tttt command accepts the following options:
-
- _----_jjjj _j_o_b__i_d Specifies a particular job ID for a job where limits
- are going to be changed. You must have the
- CAP_MAC_WRITE and CAP_PROC_MGT capabilities to change
- job limits for jobs that belong to other users. The
- job ID is printed out in hexadecimal. When the job
- ID is specified, the "0x" prefix is optional.
-
- _----_hhhh Specifies that the maximum limit values for a job are
- displayed or modified. If you do not specify the _----_hhhh
- option, the _jjjj_llll_iiii_mmmm_iiii_tttt command displays or modifies
- current limit values.
-
- _l_i_m_i_t__n_a_m_e _v_a_l_u_e Displays or sets the value for the specified limit.
-
- +o If no limit name is specified, _jjjj_llll_iiii_mmmm_iiii_tttt displays
- the values for all limits.
-
- +o If the limit name is specified without a value,
- _jjjj_llll_iiii_mmmm_iiii_tttt displays the value for the limit.
-
- +o If both a limit name and a value are specified,
- _jjjj_llll_iiii_mmmm_iiii_tttt sets the appropriate value for the limit.
-
- If the _----_jjjj option with a _j_o_b__i_d argument is specified, the _jjjj_llll_iiii_mmmm_iiii_tttt command
- will print out the following information:
-
- _%%%% _jjjj_llll_iiii_mmmm_iiii_tttt _----_jjjj _0000_xxxx_1111_4444
