Progress

ok I made some progress:

Code:
 
 #!/bin/ksh
 #Reroute to directory of used files
 cd /class/
 #Create function to handle exit function
 function usage{
 echo "Usage $0 inputfile outputfile"
 echo "The inputfile must have the text \"${must_have_text}\""
 exit 1
 }
 #Make the asg6s accept only two arguements
 if [ $# -ne 2 ]; then
 echo "Does not equal two arguments"
 usage
 fi
 #Creates file containing Message Holder
 #Have a variable for the message
 must_have_text="Message Holder"
 #Determine if first argument is empty or null
 #Create variables
 infile=$1
 outfile=$1
 if [ ! -f "${infile}"]; then
 echo "File ${infile} does not exist"
 usage
 fi
 if [ $(grep -c "${must_have_text}" ${infile}) -eq 0; then
 echo "${infile} must have 1 or more times the text ${must_have_text}"
 usage
 fi
 cp ${infile} ${outfile}

I keep getting this error though: ./asg6s: line 3: syntax error at line 6: `echo' unexpected

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

NAME
make_sockdfc - Generates frozen configuratyion file for SOCKS server SYNOPSIS
make_sockdfc [infile [outfile] ] DESCRIPTION
make_sockdfc reads in a plain-text configuration file for the SOCKS server and produces a frozen configuration file as the output. Both arguments are optional. The default for infile is /etc/sockd.conf; the default for outfile is /etc/sockd.fc. You may specify infile while omitting outfile, but you cannot specify outfile without also speficying infile. The contents of the frozen configuration file is essentially the memory image of the parsed input file. Using the frozen configuration file can reduce the start-up delay of the SOCKS server program since it no longer has to parse the file contents. When the SOCKS server starts, it always looks for the frozen configuration file /etc/sockd.fc first. If that file is not found, it then tries to use the plain-text configuration file /etc/sockd.conf. If you use frozen configuration, you must remember to run make_sockdfc every time after you modify the plain-text file or the SOCKS server will continue to use the frozen file of a previous configuration. To find out the contents of a frozen configuration file, use dump_sockdfc. FILES
