Here's what I'm trying to do:
I have several git repos. I want to setup a push-to-deploy script for each of them. being so lazy to do that for each and every repo, I wanted to script it.

My script generates a post-receive file for each repo.

here is it:


for i in $(ls $REPOS)

           echo -e '
from, to, branch = " "\r
 # 3. Copy files to deploy directory\r
deploy_to_dir = File.expand_path('$DEPLOY_DIR')\r
`GIT_WORK_TREE="#{deploy_to_dir}" git checkout -f master`\r
puts "DEPLOY: master(#{to}) copied to '#{deploy_to_dir}'"\r
        chmod +x $POST_RECEIVE_DIR

Alright so notice that the only part that changes in the generated file is where $DEPLOY_DIR lies.
and $DEPLOY_DIR changes with each iteration.
The problem is: ALL the generated files have the LAST value of $DEPLOY_DIR.

To debug I tried to echo the variable values in various places in the script and they all produce the desired outputs.
I thought it could be a problem with the buffers not being flushed. so I tried to use the sync command.
I tried using cat instead of echo.
I tried to pass the file as a parameter to a python script where I write to the file and flush the buffer.

I was all no use.
Help me.
