Hello Sharong,

Kindly use code tags as per forum rules for commands and codes which you are using in your post. Following may help you in same.

Code:
awk '{for(i=1;i<=NF;i++){if($i == "aaa"){A++} if($i == "123"){B++}}} END{print "aaa: " A ORS "123: " B}'  Input_file

Output will be as follows.
Code:
aaa: 4
123: 2

Thanks,
R. Singh

Is this homework?

you can easely create a histogram with:
Code:
cat <file.txt> | tr ' ' '\n' | sort | uniq -c | sort -rn

this will give you the count for any words in input file.
if you just want a specific word , grep for it !
hope it helps.

Hi,

Please specify what have you done to solve this by yourself , it would avoid people being suspicious :-)
there are many ways to find it, try this one:
Code:
grep -o -c 'aaa' <FileName>; grep -o -c '123'  <FileName>
