how to find and replace (sub) a pattern match in multiple files? 3

[QueenAnne]

I need to change a pattern match on multiple lines in multiple files. How do I do this?
Say for example: Files a.java, b.java, c.java... have hard coded passwords that need to be changed and the password could be on multiple lines not within a set column. Thanks very much for any assistance.

This is untested, but may get you started.
{
if (FNR==1){
if (fn) close(fn)
fn = "new" FILENAME
}
gsub("oldpwd","newpwd")
print>fn
}

ok,
Thank you CaKiwi. I found a way to do this using sed and it works for the most part. The only problem I have now is that sed is matching too much.

for FILE in *java
do
cat $FILE sed 's/devPassword/prodPassword/' > tmpFile
cp tmpFile $FILE
done
rm tmpFile

this will match devPassword, devPassword2, devPassword32323
this is not specific enough, I want to change only the patterns matching "devPassword".
I have tried 's/\<devPassword\>/prodPassword/', but it does not work.

for FILE in *java
do
sed 's/devPassword[ ]+/prodPassword/' $FILE > tmpFile
cp tmpFile $FILE
done
rm tmpFile

Or perhaps

sed 's/devPassword\([ ]+\)/prodPassword\1/' $FILE > tmpFile

If the password can be delimited by characters other than a space, put them in the square brackets.

If the password is a literal string surrounded by doublequotes, you may consider something like this:
for f in *.java; do
cp $f $f.bak
sed 's!"oldPassword"!"newPassword"!g' $f.bak >$f
done

Hope This Help, PH.
