I need some Linux grep command basics help. What I need to do is find out how many times a word appeared in text file. Right now I run grep command:
grep 'my-word' file
It shows me 100s of line. Instead of I need to show a count of ‘my-word’ and store in Linux shell variable.
The grep command searches for words or string in each FILE. You need to run the grep command following:
grep -c 'my-word' file
Where,
-c option suppress normal output; instead print a count of matching lines for each input file. With the -v, --invert-match option, count non-matching lines.
I strongly suggest that you read the following grep tutorial:
