Here is a comparison of the shell script and perl script. Both produce a line at "2345" so that you can see they are working and that the calculations match:
producing:
I am not suggesting that you must do this in perl, but I think you can see that shell is probably not the best choice.

hash
hash(1) User Commands hash(1)NAME
hash, rehash, unhash, hashstat - evaluate the internal hash table of the contents of directories
SYNOPSIS
/usr/bin/hash [utility]
/usr/bin/hash [-r]
sh
hash [-r] [name]...
csh
rehash
unhash
hashstat
ksh
hash [name]...
hash [-r]
DESCRIPTION
/usr/bin/hash
The /usr/bin/hash utility affects the way the current shell environment remembers the locations of utilities found. Depending on the argu-
ments specified, it adds utility locations to its list of remembered locations or it purges the contents of the list. When no arguments are
specified, it reports on the contents of the list. The -r option causes the shell to forget all remembered locations.
Utilities provided as built-ins to the shell are not reported by hash.
sh
For each name, the location in the search path of the command specified by name is determined and remembered by the shell. The -r option to
the hash built-in causes the shell to forget all remembered locations. If no arguments are given, hash provides information about remem-
bered commands. The Hits column of output is the number of times a command has been invoked by the shell process. The Cost column of output
is a measure of the work required to locate a command in the search path. If a command is found in a "relative" directory in the search
path, after changing to that directory, the stored location of that command is recalculated. Commands for which this will be done are indi-
cated by an asterisk (*) adjacent to the Hits information. Cost will be incremented when the recalculation is done.
csh
rehash recomputes the internal hash table of the contents of directories listed in the path environmental variable to account for new com-
mands added.
unhash disables the internal hash table.
hashstat prints a statistics line indicating how effective the internal hash table has been at locating commands (and avoiding execs). An
exec is attempted for each component of the path where the hash function indicates a possible hit and in each component that does not begin
with a '/'.
ksh
For each name, the location in the search path of the command specified by name is determined and remembered by the shell. The -r option to
the hash built-in causes the shell to forget all remembered locations. If no arguments are given, hash provides information about remem-
bered commands.
OPERANDS
The following operand is supported by hash:
utility The name of a utility to be searched for and added to the list of remembered locations.
OUTPUT
The standard output of hash is used when no arguments are specified. Its format is unspecified, but includes the pathname of each utility
in the list of remembered locations for the current shell environment. This list consists of those utilities named in previous hash invoca-
tions that have been invoked, and may contain those invoked and found through the normal command search process.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of hash: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
PATH Determine the location of utility.
EXIT STATUS
The following exit values are returned by hash:
0 Successful completion.
>0 An error occurred.
