Shell Programming and Scripting

I need to update an entry called "mail.RiskNavigatorFromEmailAddress" in all of the "Application.properties" files below, which are located in several different directories...

Each of these Application.properties files has the following entry:

mail.RiskNavigatorFromEmailAddress=oldemail@company.com

and I need to change it to

mail.RiskNavigatorFromEmailAddress=newemail@company.com

I dont want to go into each directory and vi the all of the files - it would take forever as there are a couple hundred of them ... is there an easier way to do this?


./uat304/com/company/rnj/config/Application.properties

#!/bin/ksh
for file in $(find . -name "Application.properties" -print); do
echo $file
sed -e 's/mail.RiskNavigatorFromEmailAddress=oldemail\@company.com/mail.RiskNavigatorFromEmailAddress=newemail\@company.com/g' < $file > ${file}.new && {
mv ${file}.new ${file}
}
done

assuming your application.properties files are not over the place and only under ./*/com/company/rnj/config

Code:

# sed -i 's/\(mail.RiskNavigatorFromEmailAddress=\).*/\1newemail@mpa.gov.sg/' ./uat*/com/company/rnj/config/Application.properties
# sed -i 's/\(mail.RiskNavigatorFromEmailAddress=\).*/\1newemail@mpa.gov.sg/' ./uat*/com/company/rnj/config/*/Application.properties

TinWalrus - Thanks! I had to do a couple of modifications and it worked like a charm! Your a savior!

ghostdog74 - Thanks for your response... the sed script didn't like the -i option, and when I removed the -i and ran it, it only changed the entry in the 1st file and none of the others... but again, with a little modification, I got it to work with ease.

Both of these were very helpful.. You responses are much appreciated!
