I use the program to change an occurance of a word throughout different files that are being tested. At first i had to Create a new script, sub2, taking the same three parameters (replacing an occurance of a word in a shell script), that treats the string to be replaced as plain text instead of as a regular expression. I did that and now I have Generalize my sub2 script, producing a new script sub3 that will apply a substitution to any number of files given on the command line. For example
~/UnixCourse/scriptAsst/sub3 foo bar myFile1.txt myFile2.txt
myFile3.txt

should apply the same substitution throughout each of the three files named there.
I took that part out and now i have

Code:
#!/bin/sh
File1="$3"
File2="$4"
File3="$5"
testNum="$File1"

for file in ~/*
do
echo $testNum

 A="$1"
echo $A
 B="$2"
 C="$3"
echo "$A" | sed -e 's/\([*.[^$]\)/\\\1/g' > temporary
 A="`cat 'temporary'`"
rm temporary
echo "$A"

sed "s/$A/$B/g" "$C" > myFile.txt.updated
mv myFile.txt.updated "$C"
cat "$C"

done
