Not able to configure hadoop

Not able to configure hadoop

I am not able to configure hadoop for stand alone operation. When i am
doing cp conf/*.xml input, i am getting these errors: cp: cannot create
regular file input/capacity-scheduler.xml': Permission denied cp: cannot
create regular fileinput/core-site.xml': Permission denied cp: cannot
create regular file input/fair-scheduler.xml': Permission denied cp:
cannot create regular fileinput/hadoop-policy.xml': Permission denied cp:
cannot create regular file input/hdfs-site.xml': Permission denied cp:
cannot create regular fileinput/mapred-queue-acls.xml': Permission denied
cp: cannot create regular file `input/mapred-site.xml': Permission denied
And after that when i am doing bin/hadoop jar hadoop-examples-*.jar grep
input output 'dfs[a-z.]+',i am getting these errors:
/cygdrive/d/hadoop-1.2.1/libexec/../conf/hadoop-env.sh: line 55: $'\r':
command not found Error: JAVA_HOME is not set. I have edited the env.sh
file and have set the JAVA_HOME.
Can anyone suggest me something?
