How to count all spaces in a file in Unix
bash, gnu-coreutils
Solution
Use `grep` and `wc` in a way like this to count the occurrences of spaces:
grep -o ' ' | wc -l
`grep -o` will print every match in a separate line. The number of those lines can afterwards counted easily using `wc -l`
Problem
I want to count all the spaces from my file in Unix and I have tried the following command: ``` grep " " file1 | wc ``` It is giving me the following output: ``` 3 6 34 ``` There are three spaces in my file so is it accurate command and further more how can I filter this to get exactly the spaces so only '3' should come as output and also how can I remove it
