Question how to grep only one string pr match


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.

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.
