![]() ![]() This is a utility which is exactly equivalent to grep -F that you should use if your search string is a plain text string with no regular expressions in it. It's because you're not using those two option that I believe you get those "no such file or directory" errors. And the corresponding option to xargs for receiving these as nul-delimited file names is -0. This ( -print0) means each file name will be delimited by a nul character ( \0) rather than a space character. ![]() To be able to pass these properly between find and grep we do $ find / -type f \! -perm -o=x -name "*.txt" -print0 | xargs -0 grep texthere Some file names might have spaces in them, or other wonky character that we usually don't want in file names. ![]() One is a safety thing, and the other may possibly improve speed a tiny bit. Now, there's a couple of more things we can do. I'm also specifying that I want files ( -type f) that are not executable ( \! -perm -o=x) (the ! needs to be escaped so that your shell doesn't do funny things with it). with / here, because that's where I think you are (correct me if I'm wrong). Since it looks like you're only interested in plain text files, we can exclude any other type of file (executables): $ find / -type f \! -perm -o=x -name "*.txt" | xargs grep texthere You can use find to narrow down the amount of files to look at.Īt the moment, you have $ find. It's just an awful lot of files to search. It will take a long time no matter what you do. If you want to search absolutely all files on the whole system, than what you're doing is pretty much right. But since you say it takes an awfully long time, I'm leaning more towards the first assumption (the root directory). The -i option is used for the case-insensitive search.If you're getting errors about permissions (you don't say you do), then I'm guessing you're standing in either the root directory ( /) or in some path where you don't have permission to read all files, such as in /etc or in /var. The grep command provides different attributes where we can also search as case-insensitive mode. $ grep -r "linuxtect" /home/ismail Search Recursively and Case-insensitive In the following example, we will search with the absolute path /home/ismail. Using absolute path also prevents mistakes and can be used from any working directory. The absolute path specifies the complete path without any relativity. Search Specified Absolute Path Recursively with grep CommandĪnother way to search recursively with the grep command is searching with the absolute path. In the following example, we search the current working directory’s parent directory. ![]() Relative paths are used to specify files and folders according to the current working directory. The grep command can be used to search recursively for the specified relative path. Search Specified Relative Path Recursively with grep Command The -r option is used for recursive search. In the following example, we will search recursively the current working directory. The current working directory is expressed with the dot. The first example of searching recursively with grep is searching the current working directory. Search Current Working Directory Recursively with grep Command The grep command recursive option is used to make a search in all specified paths and subdirectories for all files and child files for the specified term. The grep command is a great tool to search all directories and subdirectories for their contents. ![]()
