You are obviously mixing shell and Perl variables here.
Generally you should avoid this mixture because Perl is powerful enough
to get rid of all shell escapes, and Perl has built-ins of almost all Unix syscalls
which render them completely redundant.
Not only degrades this the performance of your Perl program
(though this is seldom an issue for the quick and dirty hack),
but it also makes your programs more insecure,
which indeed is relevant for e.g. CGIs or server programs.
(n.b. if you can afford the time you should read perldoc perlsec )

But if you are reluctant to rewrite your shell script wrapper into your Perl code
then you could either pass shell variables to the called Perl script
e.g.
Code:
$ (user_info="abc /def/ghi/abc"; perl -le '$my_path=$ARGV[1];print $my_path' $user_info)
/def/ghi/abc

or you could access the shell variables via the %ENV hash,
provided you export them in your shell wrapper script
e.g.
Code:
$ (user_info="abc /def/ghi/abc" perl -le '$my_path=$ENV{user_info};print $my_path' $user_info)
abc /def/ghi/abc

mailstats

mailstats(8)						      System Manager's Manual						      mailstats(8)

NAME

       mailstats - Displays statistics about mail traffic

SYNOPSIS

       mailstats [-o] [-C cffile [-f stfile]

FLAGS

       Do  not	display the name of the mailer in the output.  Use cffile as the name of the sendmail "cf" file instead of /var/adm/sendmail/send-
       mail.cf.  Use stfile as the input statistics file instead of /var/adm/sendmail/sendmail.st.

DESCRIPTION

       The mailstats command reads the information in the /var/adm/sendmail/sendmail.st file (or in the file specified with the -f flag),  formats
       it,  and  writes  it to standard output.  Note also that you can change the location of the sendmail.st file by editing its pathname in the
       sendmail.cf file.

EXAMPLES

       The format of the information is shown in the following example, in which the first field (M) contains a number that indicates the position
       of  that  mailer  in  the sendmail.cf file, starting at 0 (zero).  For example, the first mailer in the sendmail.cf file corresponds to the
       number 0 in the mailstats display, the second mailer corresponds to the number 1, and so on.  Statistics from Thu Feb 17  11:20:01  2000  M
       msgsfr	bytes_from    msgsto	 bytes_to   msgsrej msgsdis  Mailer 1	    50	       77K	  1	     3K        0       0   local 6
       43	  59K	    58		99K	    0	     0	   smtp  ============================================================  T	93
       136K	   59	      102K	   0	   0 The fields in the report have the following meanings: Indicates the position of the mailer in
       the sendmail.cf file.  Indicates the number of messages received by the local machine from the indicated mailer.  Indicates the	number	of
       bytes  in  the  messages  received  by  the  local machine from the indicated mailer.  Indicates the number of messages sent from the local
       machine using the indicated mailer.  Indicates the number of bytes in the messages sent from the local machine using the indicated  mailer.
       Indicates the number of rejected messages.  Indicates the number of discarded messages.	Indicates the name of the mailer.

       If sendmail transmits mail directly to a file, such as the dead.letter file or an alias target, the message and byte counts are credited to
       the prog mailer, as defined in the sendmail.cf file.  However, mailstats will still default to var/adm/sendmail/sendmail.st.

FILES

       Specifies the command path Contains system statistics Contains configuration information for sendmail
