If you want +1 for each line
Code:
grep -c am file

If you want +1 for each occurrence
Code:
grep -o am file | wc -l #with GNU grep

You could try the commands. Even if it doesn't work, it won't crash your system at least.
Anyway, I meant

for sample file :
Code:
i am very tired. am
i am busy
i am hungr

Code:
grep -o am file | wc -l
4

Code:
grep -c am file
3


Hope its clear.
