# Drive Map is an automatic drive mapping tool for Mac OS X, which maps local
# network servers when the computer initially logs in, wakes, and sleeps.
# The tool utilizes the keychain access app in Mac OS X to retrieve 
# generic internet passwords associated with usernames tied to server paths
# you wish to mount. 

# ------------------------------------------------------------------------------------------------------------------------- #

# Define the file to read for the list of servers to attempt to mount
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
INPUT_FILE="$DIR/MOUNTLIST.txt"

# Function to get the users password from the keychain access app.  This way we don't hardcode passwords into the bash script
get_pw () {
  security 2>&1 >/dev/null find-internet-password -ga $USERNAME | ruby -e 'print $1 if STDIN.gets =~ /^password: "(.*)"$/'
}

# Iterate over lines in input file, ignore blank lines with "grep -v "^$"
#for l in $(cat "$INPUT_FILE" | grep -v "^.*$"); do
cat $INPUT_FILE | while read $(echo l | grep -v "^$"); do
