; should only be used for commands that accept only one argument. When type is binary, grep may treat non-text bytes as line terminators even without the -z option. Specifying -U overrules this guesswork, causing all files to be read and passed to the matching mechanism verbatim; if the file is a text file with CR/LF pairs at the end of each line, this will cause some regular expressions to fail. 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 … grep -riI 'scanner' /home/bob/ 2>/dev/null Just not sure how to get it to work *.c and *.java files. 12 Grep Command Examples.

You have to pipe multiple commands together; one command to transverse the directories, and one command to look for the pattern within each file found. example might want search instances of string within source tree, looking *.php files, not else - *.jpg etc. 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. The first operation took me about 10 seconds. If grep decides the file is a text file, it strips the CR characters from the original file contents (to make regular expressions with ^ … --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.

This means choosing binary versus text can affect whether a pattern matches a file. For example, rg -tpy foo limits your search to Python files and rg -Tjs foo excludes JavaScript files from your search.
