for a=cat filename |tr -d 'eioubcdfghjklmnpqrstvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890()~`!@#$%^&*"()_+{}|:"<>?,./;][=-/n ' |grep a|wc -m
for e=cat filename |tr -d 'aioubcdfghjklmnpqrstvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890()~`!@#$%^&*"()_+{}|:"<>?,./;][=-/n ' |grep e|wc -m
for i=cat filename |tr -d 'aeoubcdfghjklmnpqrstvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890()~`!@#$%^&*"()_+{}|:"<>?,./;][=-/n ' |grep i|wc -m
for o=cat filename |tr -d 'aeiubcdfghjklmnpqrstvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890()~`!@#$%^&*"()_+{}|:"<>?,./;][=-/n ' |grep o|wc -m
for u=cat filename |tr -d 'aeiobcdfghjklmnpqrstvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890()~`!@#$%^&*"()_+{}|:"<>?,./;][=-/n ' |grep u|wc -m


it will give the no of time that vowel has been occured


for searching the string
cat filename | grep 'aeiou'

Even the below command can be used:

grep -io [aeiou] filename | wc -w

For 'a'
cat file_name | tr -cd 'a' | wc -m

For 'e'
cat file_name | tr -cd 'e' | wc -m

For 'i'
cat file_name | tr -cd 'i' | wc -m

For 'o'
cat file_name | tr -cd 'o' | wc -m

For 'u'
cat file_name | tr -cd 'u' | wc -m

I am giving the 3 ways to solve this problem..

1) grep -io "[aeiouAEIOU]" filename | sort | uniq -c

2) cat filename | sed 's/[a-zA-Z]/&n/g' | sed 's/^ //' | grep "[aeiouAEIOU]" | sort | uniq -c

3) cat filename | fold -1 | sort | sed -n '/^[aeiouAEIOU]/p' | uniq -c

Thanks
All codes are tested and working....
