[gentoo-user] Is grep broken?
Hello list, Can anyone explain this to me? $ /bin/grep -r hmenu *html index.html: master.html: pictures.html: $ /bin/grep -r hmenu pages/*html pages/community.html: pages/contacts.html: pages/history.html: pages/music.html: pages/news.html: pages/people.html: pages/pictures.html: Grep is clearly disobeying the recursion command. I started noticing this a few days ago, and it's making maintenance of this directory hard work. -- Rgds Peter

You told it to grep through all the html files starting from pages/ and it did so. You did not tell it to start from pages/.. so why do you think it should do so? -- alan dot mckinnon at gmail dot com

Therefore, only files that are ending with html are searched recursively. If you had placed the files in a directory called blablahtml, then grep would have searched there. > $ /bin/grep -r hmenu pages/*html > pages/community.html: > pages/contacts.html: > pages/history.html: > pages/music.html: > pages/news.html: > pages/people.html: > pages/pictures.html: > > Grep is clearly disobeying the recursion command.

No, you just did not tell it to search in the the directory pages. :) HTH Patrick signature.asc Description: This is a digitally signed message part.

It does work the way you want it to, just not the way you told it to :) -- Neil Bothwick Multitasking: Reading in the bathroom. signature.asc Description: PGP signature

Man grep didn't mention it in the "see also" section. Apropos didn't mention it either, since it wasn't installed at the time :-( -- Rgds Peter

I started noticing this a few days ago, and it's making maintenance of this directory hard work. As other have pointed out, the behaviour of grep is correct in the examples above. You could use the --include directive : grep -r --include=*html hmenu . Basically, this tells grep to recursive look for hmenu in any files that include *html starting from the current directory (* would be equally fine if you didn't want to search in 'hidden' dot directories).
