find and Replace String in Perl - Regexp
Trying to find and replace one string with another string in a file

Code:
#!/usr/bin/perl

	$csd_table_path = "/file.ntab";
	$find_str = '--bundle_type=021';
	$repl_str = '--bundle_type=021 --target=/dev/disk1s2';
	if( system("/usr/bin/perl -p -i -e 's/$find_str/$repl_str/' $csd_table_path") != 0 ) {
		print "\n\n\nERROR: adding new target to <$csd_table_path>!\n\n\n";
		exit 1;
	}
	print "Msg: file modified \n";

exit 0;

however getting errors ...

Bareword found where operator expected at -e line 1, near "--target"
(Missing operator before target?)
Unknown regexp modifier "/v" at -e line 1, at end of line
syntax error at -e line 1, near "--target"
Execution of -e aborted due to compilation errors.

atomic_inc

atomic_inc(3C)															    atomic_inc(3C)

NAME

       atomic_inc,   atomic_inc_8,   atomic_inc_uchar,	 atomic_inc_16,   atomic_inc_ushort,   atomic_inc_32,  atomic_inc_uint,  atomic_inc_ulong,
       atomic_inc_64,	atomic_inc_ptr,   atomic_inc_8_nv,   atomic_inc_uchar_nv,   atomic_inc_16_nv,	atomic_inc_ushort_nv,	 atomic_inc_32_nv,
       atomic_inc_uint_nv, atomic_inc_ulong_nv, atomic_inc_64_nv, atomic_inc_ptr_nv - atomic inrement operations

SYNOPSIS

       #include <atomic.h>

       void atomic_inc_8(volatile uint8_t *target);

       void atomic_inc_uchar(volatile uchar_t *target);

       void atomic_inc_16(volatile uint16_t *target);

       void atomic_inc_ushort(volatile ushort_t *target);

       void atomic_inc_32(volatile uint32_t *target);

       void atomic_inc_uint(volatile uint_t *target);

       void atomic_inc_ulong(volatile ulong_t *target);

       void atomic_inc_64(volatile uint64_t *target);

       void atomic_inc_ptr(volatile void *target);

       uint8_t atomic_inc_8_nv(volatile uint8_t *target);

       uchar_t atomic_inc_uchar_nv(volatile uchar_t *target);

       uint16_t atomic_inc_16_nv(volatile uint16_t *target);

       ushort_t atomic_inc_ushort_nv(volatile ushort_t *target);

       uint32_t atomic_inc_32_nv(volatile uint32_t *target);

       uint_t atomic_inc_uint_nv(volatile uint_t *target);

       ulong_t atomic_inc_ulong_nv(volatile ulong_t *target);

       uint64_t atomic_inc_64_nv(volatile uint64_t *target);

       void *atomic_inc_ptr_nv(volatile void *target);

       These functions enable the inrementing (by one) of the value stored in target to occur in an atomic manner.

       The *_nv() variants of these functions return the new value of target.

       No errors are defined.

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Interface Stability	     |Stable			   |
       +-----------------------------+-----------------------------+
       |MT-Level		     |MT-Safe			   |
       +-----------------------------+-----------------------------+

       atomic_add(3C),	 atomic_and(3C),   atomic_bits(3C),   atomic_cas(3C),	atomic_dec(3C),  atomic_or(3C),  atomic_swap(3C),  membar_ops(3C),
       attributes(5), atomic_ops(9F)

       The *_nv() variants are substantially more expensive on some platforms than the versions that do not return values. Do not use them  unless
       you need to know the new value atomically.
