Another guess what you might want:
Code:
while IFS= read pat
do
  printf "%s match %s times\n" "$pat" $(grep -c "$pat" input_file)
done < pattern_file

Code:
hot.*aaa.* match 2 times
cold.*bbb.* match 1 times
cold.*aaa.* match 2 times

NAME
git-grep - Print lines matching a pattern SYNOPSIS
git grep [-a | --text] [-I] [-i | --ignore-case] [-w | --word-regexp] [-v | --invert-match] [-h|-H] [--full-name] [-E | --extended-regexp] [-G | --basic-regexp] [-F | --fixed-strings] [-n] [-l | --files-with-matches] [-L | --files-without-match] [-z | --null] [-c | --count] [--all-match] [-q | --quiet] [--max-depth <depth>] [--color[=<when>] | --no-color] [-A <post-context>] [-B <pre-context>] [-C <context>] [-f <file>] [-e] <pattern> [--and|--or|--not|(|)|-e <pattern>...] [--cached | --no-index | <tree>...] [--] [<pathspec>...] DESCRIPTION
Look for specified patterns in the tracked files in the work tree, blobs registered in the index file, or blobs in given tree objects. OPTIONS
--cached Instead of searching tracked files in the working tree, search blobs registered in the index file. --no-index Search files in the current directory, not just those tracked by git. -a, --text Process binary files as if they were text. -i, --ignore-case Ignore case differences between the patterns and the files. -I Don't match the pattern in binary files. --max-depth <depth> For each <pathspec> given on command line, descend at most <depth> levels of directories. A negative value means no limit. -w, --word-regexp Match the pattern only at word boundary (either begin at the beginning of a line, or preceded by a non-word character; end at the end of a line or followed by a non-word character). -v, --invert-match Select non-matching lines. -h, -H By default, the command shows the filename for each match. -h option is used to suppress this output. -H is there for completeness and does not do anything except it overrides -h given earlier on the command line. --full-name When run from a subdirectory, the command usually outputs paths relative to the current directory. This option forces paths to be output relative to the project top directory. -E, --extended-regexp, -G, --basic-regexp Use POSIX extended/basic regexp for patterns. Default is to use basic regexp. -F, --fixed-strings Use fixed strings for patterns (don't interpret pattern as a regex). -n Prefix the line number to matching lines. -l, --files-with-matches, --name-only, -L, --files-without-match Instead of showing every matched line, show only the names of files that contain (or do not contain) matches. For better compatibility with git diff, --name-only is a synonym for --files-with-matches. -z, --null Output instead of the character that normally follows a file name. -c, --count Instead of showing every matched line, show the number of lines that match. --color[=<when>] Show colored matches. The value must be always (the default), never, or auto. --no-color Turn off match highlighting, even when the configuration file gives the default to color output. Same as --color=never. -[ABC] <context> Show context trailing (A -- after), or leading (B -- before), or both (C -- context) lines, and place a line containing -- between contiguous groups of matches. -<num> A shortcut for specifying -C<num>. -p, --show-function Show the preceding line that contains the function name of the match, unless the matching line is a function name itself. The name is determined in the same way as git diff works out patch hunk headers (see Defining a custom hunk-header in gitattributes(5)). -f <file> Read patterns from <file>, one per line. -e The next parameter is the pattern. This option has to be used for patterns starting with - and should be used in scripts passing user input to grep. Multiple patterns are combined by or. --and, --or, --not, ( ... ) Specify how multiple patterns are combined using Boolean expressions. --or is the default operator. --and has higher precedence than --or. -e has to be used for all patterns. --all-match When giving multiple pattern expressions combined with --or, this flag is specified to limit the match to files that have lines to match all of them. -q, --quiet Do not output matched lines; instead, exit with status 0 when there is a match and with non-zero status when there isn't. <tree>... Instead of searching tracked files in the working tree, search blobs in the given trees. -- Signals the end of options; the rest of the parameters are <pathspec> limiters. <pathspec>... If given, limit the search to paths matching at least one pattern. Both leading paths match and glob(7) patterns are supported. EXAMPLES
git grep time_t -- *.[ch] Looks for time_t in all tracked .c and .h files in the working directory and its subdirectories. git grep -e '#define' --and ( -e MAX_PATH -e PATH_MAX ) Looks for a line that has #define and either MAX_PATH or PATH_MAX. git grep --all-match -e NODE -e Unexpected Looks for a line that has NODE or Unexpected in files that have lines that match both.
