The remote servers have thousands of CSV files organized into 3 groups. The user supplies a start and end date and the script returns the records between the supplied dates/times. The script must first determine which files should contain the correct data (determined by file name = $filelist) then determine which lines from those files are between the start and end date (determined by unix timestamp field). The perl functions are to convert the user-supplied start and end date/time to epoch timestamp so time is relative to the server, not the user. This enabled me to skip time zone and DST implementation in the GUI since users can be in different time zones.
I did run the commands from an interactive session, which is a convenient way to test since it mimics what plink is doing. This is where I was seeing the undefined variable messages. When i included a pwd command, I found that the cd command was not executed either.
Since the initial post though, I learned that quoting the heredoc delimiter works. All the commands appeared to have run in bash and provided an output.
Code:
/bin/bash << "eof"
...
"eof"
I'm still not sure why this works but glad it does. I'm still faced with the timestamp conversion issue though. I played around with similar perl commands inside the nawk statement but am not having much luck. This issue doesn't have as big of an impact as did running the commands in bash instead of sh but it would be nice to resolve it.

DNSSEC-MAKEKEYSET(8)DNSSEC-MAKEKEYSET(8)NAME
dnssec-makekeyset - DNSSEC zone signing tool
SYNOPSIS
dnssec-makekeyset [ -a ] [ -s start-time ] [ -e end-time ] [ -h ] [ -p ] [ -r randomdev ] [ -tttl ] [ -v level ] key...
DESCRIPTION
dnssec-makekeyset generates a key set from one or more keys created by dnssec-keygen. It creates a file containing a KEY record for each
key, and self-signs the key set with each zone key. The output file is of the form keyset-nnnn., where nnnn is the zone name.
OPTIONS -a Verify all generated signatures.
-s start-time
Specify the date and time when the generated SIG records become valid. This can be either an absolute or relative time. An absolute
start time is indicated by a number in YYYYMMDDHHMMSS notation; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000. A relative
start time is indicated by +N, which is N seconds from the current time. If no start-time is specified, the current time is used.
-e end-time
Specify the date and time when the generated SIG records expire. As with start-time, an absolute time is indicated in YYYYMMDDHHMMSS
notation. A time relative to the start time is indicated with +N, which is N seconds from the start time. A time realtive to the
current time is indicated with now+N. If no end-time is specified, 30 days from the start time is used as a default.
-h Prints a short summary of the options and arguments to dnssec-makekeyset.
-p Use pseudo-random data when signing the zone. This is faster, but less secure, than using real random data. This option may be use-
ful when signing large zones or when the entropy source is limited.
-r randomdev
Specifies the source of randomness. If the operating system does not provide a /dev/random or equivalent device, the default source
of randomness is keyboard input. randomdev specifies the name of a character device or file containing random data to be used
instead of the default. The special value keyboard indicates that keyboard input should be used.
-t ttl Specify the TTL (time to live) of the KEY and SIG records. The default is 3600 seconds.
-v level
Sets the debugging level.
key The list of keys to be included in the keyset file. These keys are expressed in the form Knnnn.+aaa+iiiii as generated by dnssec-
keygen.
EXAMPLE
The following command generates a keyset containing the DSA key for example.com generated in the dnssec-keygen man page.
dnssec-makekeyset -t 86400 -s 20000701120000 -e +2592000 Kexample.com.+003+26160
In this example, dnssec-makekeyset creates the file keyset-example.com.. This file contains the specified key and a self-generated signa-
ture.
The DNS administrator for example.com could send keyset-example.com. to the DNS administrator for .com for signing, if the .com zone is
DNSSEC-aware and the administrators of the two zones have some mechanism for authenticating each other and exchanging the keys and signa-
tures securely.
