Extracting a word from a variable

Hi Guys,

Need you quick assistance on the below, trying to extract a word from a variable

i.e. acmi101[space]acmi102[space]acmi103[space]acmi104

When i use the following code awk '{gsub(/cmi102/,"")};1' it leaves a space in the variable, need to get rid of the space that it leaves. Any ideas.

the above result, would be

Code:
acmi101[space][space]acmi103[space]acmi104

need it to be

Code:
acmi101[space]acmi103[space]acmi104

need to get rid of the extra space.

STORE(9)						   BSD Kernel Developer's Manual						  STORE(9)

NAME
store, subyte, suswintr, suword -- store data to user-space SYNOPSIS
#include <sys/types.h> #include <sys/time.h> #include <sys/systm.h> int subyte(void *base, int byte); int suword(void *base, long word); int suword16(void *base, int word); int suword32(void *base, int32_t word); int suword64(void *base, int64_t word); #include <sys/resourcevar.h> int suswintr(void *base, int word); DESCRIPTION
The store functions are designed to copy small amounts of data to user-space. The store routines provide the following functionality: subyte() Stores a byte of data to the user-space address base. suword() Stores a word of data to the user-space address base. suword16() Stores 16 bits of of data to the user-space address base. suword32() Stores 32 bits of of data to the user-space address base. suword64() Stores 64 bits of of data to the user-space address base. suswintr() Stores a short word of data to the user-space address base. This function is safe to call during an interrupt context. RETURN VALUES
The store functions return 0 on success or -1 on failure. SEE ALSO
