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
