Given such a requirement, I would use a GNU grep (for the -o option), then pass it through wc to count the total number of occurrences:

$ grep -o -i iphone Tweet_Data | wc -l 3 

Plain grep -c on the data will count the number of lines that match, not the total number of words that match. Using the -o option tells grep to output each match on its on line, no matter how many times the match is in the line.

wc -l tells the wc utility to count the number of lines. After grep puts each match in its own line, this is the total number of occurrences of the word in the input.

If GNU grep is not available (or desired), you could transform the input with tr so that each word is on its own line, then use grep -c to count:

$ tr '[:space:]' '[\n*]' < Tweet_Data | grep -i -c iphone 3 

Given such a requirement, I would use a GNU grep (for the -o option), then pass it through wc to count the total number of occurrences:

Plain grep -c on the data will count the number of lines that match, not the total number of words that match. Using the -o option tells grep to output each match on its own line, no matter how many times the match was found in the original line.

wc -l tells the wc utility to count the number of lines. After grep puts each match in its own line, this is the total number of occurrences of the word in the input.
