If you have no clue what file may contain the needed info - then use grep and just wait. It can search millions of files in a file tree vastly quicker than you can recursively grep every single file. What you may be missing in this discussion, is that you use find if you know some part of the filename (or file mod time, or set of permissions, etc) that contains the information you need. Give that a try and compare the execution time to a recursive grep of the file tree. The zipgrep utility distributed with unzip doesnt search zip files recursively. You can use it alongside -name to search for directories. flag, find will operate in 'directory mode,' and only search for directories, not matching any files. By default, it's fully recursive, so it will search through all sub-directories to find matches. If I run this command within the src directory of the prettier. The find command is used to search through directories in Linux. This command will recursively search all files in the current directory (and its subdirectories) for the string // TODO and output the matches that it finds. name means you want to search files with. means search started from here (current place) -type means type of search item that here is file (f). type f -name '.conf' Suppose, you want to search every. In its most basic form, a simple search can look like this: rg // TODO. If you want to search special files with a wildcard, you can use the following code: find. It treats them as ordinary files, so it wont find anything except in members that are stored in raw format (which mostly happens for very small files). The name of the ripgrep executable is rg. find path -type f -name "vsim.log" -execdir grep -H 'Elapsed time' ' parameter expansion on the variable $match is used to parse the filename from filename:Elapsed time returned by grep -H (the %:* simply being used to trim everything to the first : from the right of $match) The zgrep utility from zutils doesnt support zip files at all. So just remove -w since that explicitly does what you dont want: grep -rn /path/to/somewhere/ -e 'pattern'. Continuing from my comment, you can use find to locate the file vsim.log if you do not know its exact location and then use the -execdir option to find to grep the file for the term Elapsed time, e.g. explainshell helpfully explains your command, and gives an excerpt from man grep: -w, -word-regexp Select only those lines containing matches that form whole words. Then combine find and the non-recursive use of grep, as a portable solution : find /dir \( -name node_modules -prune \) -o -name "*.sh" -exec grep -color -Hn "your text to find" debugger. If support for -print0 and -0 are compiled in, then you can use xargs to invoke grep for many files at once: find /some/dir -type f -print0 xargs -0 grep -H PATTERN. When -R options is used, The Linux grep command will search. Combine find to traverse directories recursively with grep. Use find, for excluding directories foo and bar : find /dir \( -name foo -prune \) -o \( -name bar -prune \) -o -name "*.sh" -print To grep All Files in a Directory Recursively, we need to use -R option. Grep includes a number of options that control its behavior. I applied same with two different approach, and result is not as expected. I searched that and find a solution Windows recursive grep command-line. The items in square brackets are optional. 'main' in my project on windows OS recursively. What does work, if you are trying to locate a pattern in files of filetype: grep 'pattern' find. I have AIX 7.1.0.0 and neither grep -r or -R function recursively. The command above says to search recursively starting in current directory ignoring case on the pattern and to only search in files that match the glob pattern '.cpp'. The syntax for the grep command is as follows: grep OPTIONS PATTERN FILE. The linked question is different, does not address AIX and does not offer a working solution. I will modify my question to better explain the recursive need of my search. The purpose of this solution is not to deal with grep performance but to show a portable solution : should also work with busybox or GNU version older than 2.5. If you are using GNU grep, then you can use the following: grep -ir -include '.cpp' 'xyz'. thanks for the detailed answer but I am not searching for common or related files or programs, I am searching the contents of uncommon files, such as the one I give in my example, and I need to search the contents of all files, recursively.
