NAME
+ +
+ + grep, g – search a file for a pattern
+ +
+

SYNOPSIS
+ +
+ + grep [ option ... ] pattern [ file ... ] +
+ + g [ option ... ] pattern [ file ... ]
+ +
+

DESCRIPTION
+ +
+ + Grep searches the input files (standard input default) for lines + that match the pattern, a regular expression as defined in regexp(7) + with the addition of a newline character as an alternative (substitute + for |) with lowest precedence. Normally, each line matching the + pattern is ‘selected’, and each selected line is copied to + the standard output. The options are
+ −c    Print only a count of matching lines.
+ −h    Do not print file name tags (headers) with output lines.
+ −e    The following argument is taken as a pattern. This option makes + it easy to specify patterns that might confuse argument parsing, + such as −n.
+ −i    Ignore alphabetic case distinctions. The implementation folds + into lower case all letters in the pattern and input before interpretation. + Matched lines are printed in their original form.
+ −l    (ell) Print the names of files with selected lines; don’t print + the lines.
+ −L    Print the names of files with no selected lines; the converse + of −l.
+ −n    Mark each printed line with its line number counted in its file.
+ −s    Produce no output, but return status.
+ −v    Reverse: print lines that do not match the pattern.
+ −f    The pattern argument is the name of a file containing regular + expressions one per line.
+ −b    Don’t buffer the output: write each output line as soon as it + is discovered. +
+ + Output lines are tagged by file name when there is more than one + input file. (To force this tagging, include /dev/null as a file + name argument.) +
+ + Care should be taken when using the shell metacharacters $*[^|()=\ + and newline in pattern; it is safest to enclose the entire expression + in single quotes '...'. An expression starting with ’*’ will treat + the rest of the expression as literal characters. +
+ + G invokes grep with −n and forces tagging of output lines by file + name. If no files are listed, it searches all files matching
+ +
+ + *.C *.b *.c *.h *.m *.cc *.java *.py *.tex *.ms
