Searching for a string in multiple files on Linux [closed]
You need to have read privileges on the files you will be searching in. If you do have them, then simply use
grep -r "foo" /home/thisuser/bar/baz/*to search in a certain folder or
grep "foo" /home/thisuser/bar/baz/somefile.txtif you need to search in a specific file, in this case "somefile.txt".Basically the syntax is
grep [options] [searched string] [path]// -r is an option which states that it will use recursive searchAnother useful options are "-n" to show on which line in which file the string is located, "-i" to ignore case, "-s" to suppress some messages like "can't read file" or "not found" and "-I" to ignore binary files.
If you use
grep -rnisI "foo" /home/thisuser/bar/baz/*you will exactly know where to look.
