r means to recurse texttofind is the string to search for The dot simply means start the search from the current working directory. Grep is a pattern matching command that we can use to search inside files and directories for specific text. As you’ve seen, the grep -r command makes it easy to recursively search directories for all files that match the search pattern you specify, and the syntax is much shorter than the equivalent find/grep command. When -R options is used, The Linux grep command will search. If you’re using Linux, performing a recursive grep is very easy. = to only skip the = directory in in the current directory). To grep All Files in a Directory Recursively, we need to use -R option.
! -path './=' -type f -exec grep -n SearchTextHere /dev/null + For that, you could use find to find the files and exclude = and let it call grep to search the text within the files, as you'd do anyway standardly as -r is not a standard grep option. In any case, there's no way to tell GNU grep -r to exclude only the one = in the current directory (and still search in the = files found in other subdirectories). That has no advantage over using -exclude. Here, while you could do: echo = | grep -exclude-from=/dev/stdin -rn SearchTextHere. exclude-from is for when you want to give the list of exclusion in a file. Now to exclude any file called = in a recursive search with GNU grep, you'd use: grep -rn -exclude= SearchTextHere. If that = file of yours is empty, that's one possible explanation.

Here, the -R option tells grep to search a directory recursively, while the -l option is to skip the matching information and tell grep to print only the file names of matched files. With the Rl option, the grep command can do it as well. That is running those [ or expr commands with their output redirected to =. Using the grep Command and the xargs Command As the name says, the find command can find files. Using grep to recursively search in a directory, ignoring a single file Asked 1 year, 8 months ago Modified 1 year, 8 months ago Viewed 601 times 0 Is there a way to get grep to search an entire directory, but ignore matches in ONE file The command I'm using is: grep -rn 'SearchTextHere' The file I need to ignore has a weird filename. =-named files can appear if one does: īy mistake as that's essentially the same as: > '='
