This Bash script uses the OAuth library to read tweets or send your own updates:

#!/bin/bash 
#Filename: twitter.sh 
#Description: Basic twitter client 

oauth_consumer_key=YOUR_CONSUMER_KEY 
oauth_consumer_scret=YOUR_CONSUMER_SECRET 

config_file=~/.$oauth_consumer_key-$oauth_consumer_secret-rc  

if [[ "$1" != "read" ]] && [[ "$1" != "tweet" ]]; 
then  
  echo -e "Usage: $0 tweet status_message\n   OR\n      $0 read\n" 
  exit -1; 
fi 

#source /usr/local/bin/TwitterOAuth.sh 
source bash-oauth-master/TwitterOAuth.sh 
TO_init 

if [ ! -e $config_file ]; then 
 TO_access_token_helper 
 if (( $? == 0 )); then 
   echo oauth_token=${TO_ret[0]} > $config_file 
   echo oauth_token_secret=${TO_ret[1]} >> $config_file 
 fi 
fi 

source $config_file 

if [[ "$1" = "read" ]]; 
then 
TO_statuses_home_timeline '' 'YOUR_TWEET_NAME' '10' 
  echo $TO_ret |  sed  's/,"/\n/g' | sed 's/":/~/' | \ 
    awk -F~ '{} \ 
      {if ($1 == "text") \ 
        {txt=$2;} \ 
       else if ($1 == "screen_name") \ 
        printf("From: %s\n Tweet: %s\n\n", $2, txt);} \ 
      {}' | tr '"' ' ' 

elif [[ "$1" = "tweet" ]]; 
then  
  shift 
  TO_statuses_update '' "$@" 
  echo 'Tweeted :)' 
fi
