Rails: How to run "rake" commands using Bash script?

Question

I created reset_db.sh (with chmod +x) with the following content:

#!/bin/bash
echo "*** Deleting the database ***"
rake db:drop --trace
echo "*** Creating the database ***"
rake db:create --trace
echo "*** Migrating the database ***"
rake db:migrate --trace
echo "*** Seeding the database ***"
rake db:seed --trace
echo "*** Done! ***"

However, when I run:

bash reset_db.sh

I see:

*** Deleting the database ***
*** Creating the database ***
*** Migrating the database ***
*** Seeding the database ***
*** Done! ***

but the rake commands were not executed.

Any ideas why ?

Bonus question:

What should I do in order to be able to run reset_db.sh rather than bash reset_db.sh ?

Add set -x at the top of your bash script for more verbose output.

#!/bin/bash

set -x

echo "*** Deleting the database ***"
rake db:drop --trace
echo "*** Creating the database ***"
rake db:create --trace
echo "*** Migrating the database ***"
rake db:migrate --trace
echo "*** Seeding the database ***"
rake db:seed --trace
echo "*** Done! ***"

Does that give you any further information?

to run the command you need to type:

./reset_db.sh

Regarding the rake command, are you in the folder where the rake should be launched?

I think Matteo's on to something: I can't duplicate this issue on my local project. Make sure the file is in the same location as the project's Rakefile.

Thanks! The problem was totally different from what I thought... After running dos2unix on reset_db.sh, it started to work :) Thanks anyway for your time!
