Just add the -v switch to your grep search command, like this:Īs shown in the documentation below, the -v switch stands for "in vert switch". For instance, you've been searching for pepperoni pizza orders like this:Īnd now you need to find all orders that don't have pepperoni. I open the temp file in vim so that I might edit it if I have to remove someotherthing and then save and cfile %.Īwk '/^+\:+\:/ ' $fileĮcho "You must use grep -H -n to have the right format for vim.Problem: You need to reverse the meaning of a search you're performing with the grep command. ![]() Grep something * | grep -v removeotherthing | vimgrep I built on the above to allow grep to pipe to vim. I have another variant of the above that's a little cleaner, a little nicer: It also doesn't bother starting Vim if grep returns zero matches. So my vimgrep shell script behaves just like grep does and takes all greps args. ![]() So that I can do:įind /etc | xargs vimgrep userid (for example) ![]() However, because I use it in all kinds of ways, I prefer to just have the shell script vimgrep emulate grep exactly. I did something very similar to this a while ago, and I agree it's very useful to do this from the shell. If your shell is zsh, or another that supports similar extended globbing you can just use: Yes It's correct anyway If we want to grep recursively all the *.cc *.h *.i we have to redefine the grepprg corectly Why not use the built-in :vimgrep command? In Vim set grepprg=vimgrep where vimgrep is:įind. Tip 1392 Printable Monobook Previous Next
