![]() If you add an -exec argument to find, it will execute everything you specify up to a or +. There are a bunch of ways to handle this (the ideal is to just not use spaces in file names), and the common one is to use one of the fancier features of find. This doesn't work if some of your file names have spaces in them, though, because xargs thinks the space is separating two different file names, rather than a part of one file name. The result is that grep will search every file that find finds. Xargs is a cunning little program that runs whatever you tell it to (here, grep ), after adding all the arguments it received on stdin. The | takes "standard output", aka "stdout", from find (ie what you normally see on screen) and pipes it into xarg's "standard input", aka "stdin", ie what would normally happen if you were typing into a running program. To search recursively through /tmp to find files which have the word IBM. The standard way to do this is using xargs: find. The grep command searches for the pattern specified by the Pattern parameter. Now we know the files we want to search, we need to get grep to search those files. How can I recursively search for directory names with a particular string where the string is only part of the directory name For example: the directory name is '8.0.3-99966en', but I want to recursively search for directories with the string '99966'. Add -type f to only get files listed: find. Note that we're getting folders listed too we don't want this, as grep can't search a folder itself, only the files in the folder. maxdepth 2 will likewise list for all files and folders in the current folder and any immediate subfolders. maxdepth 1 will list all the files and folders in the current folder. will list all the files and folders that exist in the current folder (. Run the commands at each stage to see what it looks like:įind. The -include flag tells grep to only include files matching a certain pattern. By default, grep will search all files in a given folder and its subfolders if you invoke it with the recursive -r flag.This will pick up everything, but if you only want certain extensions, the option you’ll want to use is -include. The one we're interested in here is -maxdepth. Only Including Certain Files in grep Searches. If you run man find, you'll get a man page of the many options that find takes. The trick is to use find to work out which files to search, and pass the file list that find produces to grep. If I try a recursive grep and the current directory does not contain at least one file in the list, I get an error (even if a. As Kent notes, you can't do this with a straight grep it simply isn't powerful enough.
