Hi

How can get all different strings in a file from a file with many equal strings?

example: <command> <option> <search-string> fromfile.txt > newfile.txt

cat <file> | grep 'word1 word2 word3' > file.txt

Put the words in single quotes ' '

That should work.

I wan`t the them only printed once. So I get just different matches in the file. none equal. So I can se how many different strings there are, cause there are many equal

Using the example you already were given:

cat <file> | grep 'word1 word2 word3' > file.txt
sort -um file.txt -o file1.txt

file1.txt now has duplicates removed.
