Did you mean to follow that with an asterisk: grep yvertohor --include={*.R,*.Rmd} * Otherwise, grep is waiting for text to appear on stdin. Without -r, you have to give grep a list of file(s) to search. This is stated in the second paragraph of the man page DESCRIPTION. You could also have used grep yvertohor *.R *.Rmd > workaround: > use the -r flag when using --include > > system: ubuntu Regards, Gary
