Mostly solved. A little advice needed to perfect.

Hello again, everybody. I've got a script that works pretty well, but only for files that are named without leading zeros. Our files are named with leading zeros. Please see the #comments# in the script which follows.

Code:

#!bin/bash
# This script works in its current form, but it's written for files that are named with the pattern pg_1.pdf, without leading zeros. Our files are named with four digits, the leading zeros being present if the page number is less than 1000. 'Need a script that will work with files named with the pattern pg_0001.pdf

a=1 #Sets the starting page equal to 1. 'Could set with user input.
b=$(($a+1))#Sets the next page equal to one more than the starting page.

Filename="pg_"$a".pdf" # This is the filename of the starting page.

until [ $b == 6 ]; do # The number sets the maximum pages to be considered for concatenation. Again, it could be set using user input.

Filename2="pg_"$b".pdf" # This is the filename of the next file to be considered for concatenation to the current file.

x=`pdfgrep -C 0 [0-9]\{7\} $Filename | head -n 1` # pdfgrep with option to capture only zero characters other than the seven digits in the employee ID; this is piped to head in order to get just the first occurrence.
y=`pdfgrep -C 0 [0-9]\{7\} $Filename2 | head -n 1`

if [ "$x" == "$y" ]; then 
    pdfjoin --rotateoversize 'false' $Filename $Filename2 --outfile $Filename # If the employee ID's are equal, then the pdf files are concatenated into a new file, which is given the name of the first file that's added to.
    rm $Filename2 # If the file is concatenated to a previous file, it is removed.
else
Filename=$Filename2 # If no match is found and the file is not concatenated, then advance the current origination file, Filename, to the name of the non-concatenated/non-matching file.

fi

b=$(($b+1)) # Advance the page number of the next file, Filename2.

done
exit

TCPSER(1)						      General Commands Manual							 TCPSER(1)

NAME

       tcpser - emulate a Hayes compatible modem

SYNOPSIS

       tcpser -d dev -s speed [-l log_level -t tracing_options] ...
       tcpser -v port [-l log_level -t tracing_options] ...

DESCRIPTION

       This manual page documents briefly the tcpser command.

       tcpser  turns  a  PC serial port into an emulated Hayes compatible modem that uses TCP/IP for incoming and outgoing connections.  It can be
       used to allow older applications and systems designed for modem use to operate on the Internet.	tcpser supports all  standard  Hayes  com-
       mands,  and  understands extended and vendor proprietary commands (though it does not implement many of them).  tcpser can be used for both
       inbound and outbound connections.

OPTIONS

       A summary of options is included below.

       -h     Show summary of options.

       -p     Port to listen on (defaults to 6400).

       -t     Trace flags: (can be combined)
		 s	modem input
		 S	modem output
		 i	IP input
		 I	IP output

       -l     Log level: 0 (NONE), 1 (FATAL) - 7 (DEBUG_X) (defaults to 0).

       -L     Log file (defaults to stderr).

       The following can be repeated for each modem desired (-s, -S, and -i will apply to any subsequent device if not set again):

       -d     Serial device (e.g. /dev/ttyS0).	Cannot be used with -v

       -v     TCP port for VICE RS232 (e.g. 25232). Cannot be used with -d

       -s     Serial port speed (defaults to 38400).

       -S     Speed modem will report (defaults to -s value).

       -I     Invert DCD pin.

       -n     Add phone entry (number=replacement).

       -a     Filename to send to local side upon answer.

       -A     Filename to send to remote side upon answer.

       -c     Filename to send to local side upon connect.

       -C     Filename to send to remote side upon connect.

       -N     Filename to send when no answer.

       -B     Filename to send when modem(s) busy.

       -T     Filename to send upon inactivity timeout.

       -i     Modem init string (defaults to `', leave off `at' prefix when specifying).

       -D     Direct connection (follow with hostname:port for caller, : for receiver).
