![]() command - bang - nargs GGrep call fzfvimgrep ( git grep -line-number -ignore-case. Only alpha, charlie, and delta match so those are the only ones that are printed. You can force case-insensitivity by passing -i to fzf. To deconstruct that regex, it first matches on a start of a line ^ and then looks for strings that do not match brav to follow afterwards. So using the example above, you can do something like this to get results you want without using grep flags. To do this you would use something known as a negative look-ahead regex: (?!). I wanted to add that using PCRE it is possible to use just regex to filter out using negate expressions. (Kanvuanza's answer)Īs you can see there were no files listed because all the files in this directory included at least one letter from that class. That will keep any files from showing up that have any of those characters. So as Kanvuanza said, to grep for the inverse of "term" as opposed to the characters t e r m you should do it using grep -v.Īlso if you don't want the files that have any characters in the class use grep -v ''. site /c 'grep -i -l '12' CONFIGPATHfile' > files.temp For some reason when I run this in the cmd line (subbing values into 1 and 2) it does not do a case-insensitive search. ![]() If you notice it included the entire directory listing because all the files had at least one letter that was not included in the character class. bat script and there is a problem with the following line: forfiles /m. Now if I run ls |grep '^' I get the following: $ ls |grep '^'Īs you can see, not only did I get brave and bravo I also got alpha because the character class will get any letter from that list.Ĭonsequently, if I run ls |grep '' I will get all the files that do not contain the characters b r a v anywhere in the name. They describe a pattern to match, a sequence of characters, not words, within a line of text. Take the following directory for instance: $ ls By default, grep is case-sensitive (use -i to ignore case). This means if a file has other letters in its name it will still appear in the output of ls. following case, grep will print every line that does not contain the string. ![]() ![]() When you run ls /directory | grep '' you are essentially grepping for not the letters t e r m. This is nice, but if you were working with a large fortran file of something. ![]()
