varaiable "a" value should be -b "FPT MAIN".
When we pass "a" to another script, we are expecing it to get substitue as ./test.sh -b "FPT MAIN". But, it is getting substituted as ./test.sh -b '"FPT' 'MAIN"', which is causing a problem.

Could someone suggest how to achieve this.


Code:
bash$ a=" -b \"FPT MAIN\" "; 
bash$ echo $a
-b "FPT MAIN"
bash$
bash$
bash$ a=" -b \"FPT MAIN\" "; echo $a ;set -x ; ./test.sh $a; set +x
-b "FPT MAIN"  # First output
+ ./test.sh -b '"FPT' 'MAIN"' # Why this causing problem? This is just showing how system handles it.
-b "FPT MAIN" # Second output - same as fist output. What is the difference.? 
+ set +x
bash$
bash$
bash$ cat test.sh
#!/bin/bash
a=$@
echo $a

idmap_rid

IDMAP_RID(8)															      IDMAP_RID(8)

NAME

       idmap_rid - Samba's idmap_rid Backend for Winbind

DESCRIPTION

       The  idmap_rid  backend provides a way to use an algorithmic mapping scheme to map UIDs/GIDs and SIDs. No database is required in this case
       as the mapping is deterministic.

IDMAP OPTIONS

       range = low - high
	  Defines the available matching uid and gid range for which the backend is authoritative. Note that the range acts as a filter. If  algo-
	  rithmically  determined  UID or GID fall outside the range, they are ignored and the corresponding map is discarded. It is intended as a
	  way to avoid accidental UID/GID overlaps between local and remotely defined IDs.

       base_rid = INTEGER
	  Defines the base integer used to build SIDs out of an UID or a GID, and to rebase the UID or GID to be obtained from a SID. User RIDs by
	  default start at 1000 (512 hexadecimal), this means a good value for base_rid can be 1000 as the resulting ID is calculated this way: ID
	  = RID - BASE_RID + LOW RANGE ID.

EXAMPLES

       This example shows how to configure 2 domains with idmap_rid

	    [global]
		idmap domains = MAIN TRUSTED1

		idmap config MAIN:backend      = rid
		idmap config MAIN:base_rid     = 1000
		idmap config MAIN:range        = 10000 - 49999

		idmap config TRUSTED1:backend  = rid
		idmap config TRUSTED1:base_rid = 1000
		idmap config TRUSTED1:range    = 50000 - 99999
