Substitution replacement not terminated

[shan_emails]

Hi All,

I have the perl file and that contents are

||/home/xx> cat test.pl
#!/usr/bin/perl -w
use strict; 
`perl -p -i -e 's/^(.{10})(.{382})(.*)$/$1^$2^$3/' test.txt`;

and when i run the file i got the below error

||/home/xx> perl test.pl
Use of uninitialized value in concatenation (.) or string at test.pl l
+ine 3.
Use of uninitialized value in concatenation (.) or string at test.pl l
+ine 3.
Use of uninitialized value in concatenation (.) or string at test.pl l
+ine 3.
Substitution replacement not terminated at -e line 2.

But when i run this command in terminal it gives correct output and don't show any error

||/home/xx> perl -p -i -e 's/^(.{10})(.{382})(.*)$/$1^$2^$3/' test.txt
||/home/xx>

Shall i know what will be the solution for this.

Thanks in advance,
Shanmugam
