how to deletes line from a text file that are taken from another file [duplicate]


Tag: shell,awk,sed,grep,sh

This question already has an answer here:

I have a data.txt file with a lot of lines in it and a lines.txt that contains some lines.

I want to delete all lines from data.txt that match any line from lines.txt and to save that new file as no_dupplicate_lines.txt. I tried this but it does not work:

LC_ALL=C fgrep -v -f dupp jour_24-06.txt

I looking for a solution a kind of File1 MINUS File2 => File1-File2


Something like this with grep:

grep -vxf lines.txt data.txt > no_dupplicate_lines.txt


AMD$ cat lines.txt
AMD$ cat data.txt
AMD$ grep -vxf lines.txt data.txt

Print the lines that are not matching (-v) the exact lines (-x) from the file lines.txt (-f lines.txt). See man grep for option details.
