guys anyone knows how to do following in Unix Shell?
Write a pipe/Shell script that will accomplish the following:
1.Count all the files in current directory that contain the word 'Windows'.
2.Count the number of times 'Windows' occurs in all the files in the current directory.
3.Delete all //... comments from a C++ program.
4.For each file in the current directory, change its name so that any upper-case letters are changed to lower case. For example 'uGLy.doC' will be changed to 'ugly.doc' Hint: generate a file that contains all the required mv operations, then execute that file

It may work. check out
1 ls ./Windows |wc -l
2.grep Windows * | wc -l
3.sed 's|//.*$||g' test1.C > test2.C
4.this is one hacked version from the net
#!/bin/sh
doren() {
newname=`echo "$1" |sed '
h
s/.*\///
y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/
x
s/[^/]*$//
G
s/\n//
'`
[ "$1" != "$newname" ] &&
{
echo "$1"
echo " --> $newname"
mv "$1" "$newname"
}
}
if [ $# -eq 1 ]
then
find "$1" -depth |
{
while read a
do
doren "$a"
done
}
else
echo "$0: usage: $0 directory"
echo "translates all file and directory names"
echo "in the specified hierachy to lower case"
fi
