IF and awk/printf
Hi Friends,

Scripting newb here. So I'm trying to create a geektool script that uses awk and printf to output certain fields from top (namely command, cpu%, rsize, pid and time, in that order). After much trial and error, I've pretty much succeeded, with one exception. Any process whose name is more than one word, such as system events or system pre..., gets the first word outputted to command ($2), the second outputted to cpu% ($3), cpu% outputted to time ($4) and so on. I'm pretty sure there's a way to fix this so that both words are outputted to the command column using if, but be as I possess very rudimentary scripting skills, I have no idea how to do this. Here's what I have so far:


Code:
top -FR -l2 -ocpu | grep -v ' 0.0% ..:' | awk '{printf( "%-12s %-5s %-5s %-5s %s\n", $2,$3,$10,$1,$4 ) }' | sed -n '15,$p'

Below is what I'm seeing.

Any help would be greatly appreciated.

Thanks,

Thom

CPUSET(3)						   BSD Library Functions Manual 						 CPUSET(3)

NAME

     cpuset_create, cpuset_destroy, cpuset_zero, cpuset_set, cpuset_clr, cpuset_isset, cpuset_size -- dynamic CPU sets

SYNOPSIS

     #include <sched.h>

     cpuset_t *
     cpuset_create(void);

     void
     cpuset_destroy(cpuset_t *set);

     void
     cpuset_zero(cpuset_t *set);

     int
     cpuset_set(cpuid_t cpu, cpuset_t *set);

     int
     cpuset_clr(cpuid_t cpu, cpuset_t *set);

     int
     cpuset_isset(cpuid_t cpu, const cpuset_t *set);

     size_t
     cpuset_size(const cpuset_t *set);

DESCRIPTION

     This section describes the functions used to create, set, use and destroy the dynamic CPU sets.

     This API can be used with the POSIX threads, see pthread(3) and affinity(3).

     The ID of the primary CPU in the system is 0.

FUNCTIONS

     cpuset_create()
	      Allocates and initializes a clean CPU-set.  Returns the pointer to the CPU-set, or NULL on failure.

     cpuset_destroy(set)
	      Destroy the CPU-set specified by set.

     cpuset_zero(set)
	      Makes the CPU-set specified by set clean, that is, memory is initialized to zero bytes, and none of the CPUs set.

     cpuset_set(cpu, set)
	      Sets the CPU specified by cpu in set.  Returns zero on success, and -1 if cpu is invalid.

     cpuset_clr(cpu, set)
	      Clears the CPU specified by cpu in the CPU-set set.  Returns zero on success, and -1 if cpu is invalid.

     cpuset_isset(cpu, set)
	      Checks if CPU specified by cpu is set in the CPU-set set.  Returns the positive number if set, zero if not set, and -1 if cpu is
	      invalid.

     cpuset_size(set)
	      Returns the size in bytes of CPU-set specified by set.

SEE ALSO

     affinity(3), pset(3), sched(3), schedctl(8), kcpuset(9)

HISTORY

     The dynamic CPU sets appeared in NetBSD 5.0.
