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

RE: How do you search the string for vowel's occurrence and number of occurrences of each vowel
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....
