Install Packages

Install both: package_download.sh and expect_package_download.sh (for this you need to have expect package installed).

package_download.sh

#!bin/bash

this_catalog=`pwd`

echo "Remember that ATHENA environment must be set!"

if [ $# -lt 1 ]
then
  echo "Too few arguments: sh package_download.sh FILE_LIST.txt"
  exit 1
fi

if [ $# -gt 1 ]
then
  echo "Too many arguments: sh package_download.sh FILE_LIST.txt"
  exit 1
fi

echo "Write CERN username:"
read cern_username

echo "Write $cern_username@cern.ch NICE password:"
read -s cern_password

while read filename
do
  if test -d $this_catalog/$filename
  then #file exist
    rm -r -f $this_catalog/$filename
  fi

  expect expect_package_download.sh $filename $cern_username $cern_password
  cd $filename/cmt
  cmt config
  cmt make
  cd $this_catalog

done < $this_catalog/$1

expect_package_download.sh

#!/usr/bin/expect

set filename [lindex $argv 0]
set user [lindex $argv 1]
set passw [lindex $argv 2]

spawn cmt co $filename

expect "assword:" 
send "$passw\r"

while { true } {
  expect {
    "assword: " { send "$passw\r" }
    "CMT" { break }
  }
}
