1. COMMAND-LINE Options       The command-line syntax for top consists of:          -hv|-bcHiOSs -d secs -n max -u|U user -p pid -o fld -w [cols]        The typically mandatory switch ('-') and even whitespace are completely optional.        -h | -v  :Help/Version            Show library version and the usage prompt, then quit.        -b  :Batch-mode operation            Starts top in Batch mode, which could be useful for sending output from top to other programs or to a file.  In this mode, top will not accept input and runs until the iterations limit you've set with the `-n' command-line option or until killed.        -c  :Command-line/Program-name toggle            Starts top with the last remembered `c' state reversed.  Thus, if top was displaying command lines, now that field will show program names, and visa versa.  See the `c' interactive command for additional information.        -d  :Delay-time interval as:  -d ss.t (secs.tenths)            Specifies the delay between screen updates, and overrides the corresponding value in one's personal configuration file or the startup default.  Later this can be changed with the `d' or `s' interactive commands.            Fractional  seconds  are honored, but a negative number is not allowed.  In all cases, however, such changes are prohibited if top is running in Secure mode, except for root (unless the `s' command-line option was used).  For additional information on            Secure mode see topic 6a. SYSTEM Configuration File.        -H  :Threads-mode operation            Instructs top to display individual threads.  Without this command-line option a summation of all threads in each process is shown.  Later this can be changed with the `H' interactive command.       -i  :Idle-process toggle            Starts top with the last remembered `i' state reversed.  When this toggle is Off, tasks that have not used any CPU since the last update will not be displayed.  For additional information regarding this toggle see topic 4c. TASK AREA Commands, SIZE.        -n  :Number-of-iterations limit as:  -n number            Specifies the maximum number of iterations, or frames, top should produce before ending.        -o  :Override-sort-field as:  -o fieldname            Specifies the name of the field on which tasks will be sorted, independent of what is reflected in the configuration file.  You can prepend a `+' or `-' to the field name to also override the sort direction.  A leading `+' will force sorting  high  to            low, whereas a `-' will ensure a low to high ordering.             This option exists primarily to support automated/scripted batch mode operation.        -O  :Output-field-names            This option acts as a form of help for the above -o option.  It will cause top to print each of the available field names on a separate line, then quit.  Such names are subject to nls translation.        -p  :Monitor-PIDs mode as:  -pN1 -pN2 ...  or  -pN1,N2,N3 ...            Monitor only processes with specified process IDs.  This option can be given up to 20 times, or you can provide a comma delimited list with up to 20 pids.  Co-mingling both approaches is permitted.             A pid value of zero will be treated as the process id of the top program itself once it is running.             This is a command-line option only and should you wish to return to normal operation, it is not necessary to quit and restart top  --  just issue any of these interactive commands: `=', `u' or `U'.            The `p', `u' and `U' command-line options are mutually exclusive.        -s  :Secure-mode operation            Starts top with secure mode forced, even for root.  This mode is far better controlled through the system configuration file (see topic 6. FILES).        -S  :Cumulative-time toggle            Starts  top  with  the  last  remembered `S' state reversed.  When Cumulative time mode is On, each process is listed with the cpu time that it and its dead children have used.  See the `S' interactive command for additional information regarding this            mode.        -u | -U  :User-filter-mode as:  -u | -U number or name            Display only processes with a user id or user name matching that given.  The `-u' option matches on  effective user whereas the `-U' option matches on any user (real, effective, saved, or filesystem).             Prepending an exclamation point ('!') to the user id or name instructs top to display only processes with users not matching the one provided.             The `p', `u' and `U' command-line options are mutually exclusive.       -w  :Output-width-override as:  -w [ number ]            In Batch mode, when used without an argument top will format output using the COLUMNS= and LINES= environment variables, if set.  Otherwise, width will be fixed at the maximum 512 columns.  With an argument, output width can be decreased or  increased            (up to 512) but the number of rows is considered unlimited.            In normal display mode, when used without an argument top will attempt to format output using the COLUMNS= and LINES= environment variables, if set.  With an argument, output width can only be decreased, not increased.  Whether using environment vari‐            ables or an argument with -w, when not in Batch mode actual terminal dimensions can never be exceeded.            Note: Without the use of this command-line option, output width is always based on the terminal at which top was invoked whether or not in Batch mode.
