For the list of supported filetypes run ag --list-file-types. SET GREP RECURSIVE ON To reset the default of no recursive search, enter the command SET GREP RECURSIVE OFF This adds a "/S" option under Windows and a "-r" option under Linux. I am trying to figure out how to search for "_iterator_tag" string in all sub directories recursively and in files with extensions .cpp, .h, .hpp, .cxx, .inl for now all I can do is search each of these file types separately as below grep -R "_iterator_tag" --include '*.cpp' Is there a quicker way to search all of these file types … Say you have a directory structure as follows: -type f | xargs grep whatever sorts of solutions will run into "Argument list to long" errors when there are too many files matched by find. When type is binary, grep may treat non-text bytes as line terminators even without the -z option. -name "*.c" -print0 | xargs --null grep -l search-pattern It uses xargs to append the search results by find. --binary-files=TYPE If the first few bytes of a file indicate that the file contains binary data, assume that the file is of type TYPE. | xargs grep text_to_find The above command is fine if you don't have many files to search though, but it will search all files types, including binaries, so may be very.

Example: grep -i 'hello world' menu.h main.c Regexp selection and interpretation: -E, --extended-regexp PATTERN is an extended regular expression -F, --fixed-strings PATTERN is a set of newline-separated strings -G, --basic-regexp PATTERN is a basic regular expression -e, --regexp=PATTERN use PATTERN as a regular expression -f, --file=FILE obtain PATTERN from FILE -i, - … Grep, no value return. I'm trying to speed up the process by not searching megabytes of binary data in some files. When searching multiple files to find the one which is missing a pattern. I think what you want instead is to find all files matching the *.c pattern (recursively) and have grep search for you in it.

How to grep through sub-directories whether or not your Unix has recursive (GNU) grep. means to search the current dir and subdirs-type f limits search to files, not directories or other file types-name '*.c' limits search to files ending in .c.Notice the non-regex syntax here!-print0 sends results to standard output delimited by null characters. 1. grep invert not working the way I expected. This adds robustness when we pipe to xargs, since filenames cannot contain null characters. Recursive grep fails for *.c files. Just as you can run a compiler from Emacs and then visit the lines with compilation errors, you can also run grep and then visit the lines on which matches were found. Here's a way to do that: find . For example, rg -tpy foo limits your search to Python files and rg -Tjs foo excludes JavaScript files from your search.
