I typed in
Code:
#!/bin/sh

# Save first two parameters
A="$1" 
B="$2"

shift 2 # Get rid of first two parameters

while [ "$#" -gt 0 ]
do
        sed "s/$A/$B/g" $1 > $1.new
        shift
done

and saved it.
I then ran the program ~cs252/bin/scriptAsst.pl
and it started running the tests. When it got to test 28 it says sub3 produced incorrect output on test 28: /Unix/Unix/sub3 '3' '9' '_aardvark.cpp'

Im guessing that it was trying to replace all occurances of '3' with '9' but the output didn't come out correct.

---------- Post updated at 07:21 PM ---------- Previous update was at 06:57 PM ----------

Basically what i need is a for loop to allow it to run through as files as it wants to. Using the following code.

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

for x in $*
do
echo $x

 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

I appreciate your patience with me very much
