Имя (Name)
grep - print lines that match patterns
Синопсис (Synopsis)
grep [OPTION...] PATTERNS [FILE...]
grep [OPTION...] -e PATTERNS ... [FILE...]
grep [OPTION...] -f PATTERN_FILE ... [FILE...]
Описание (Description)
grep searches for PATTERNS in each FILE. PATTERNS is one or more
patterns separated by newline characters, and grep prints each
line that matches a pattern. Typically PATTERNS should be quoted
when grep is used in a shell command.
A FILE of '-' stands for standard input. If no FILE is given,
recursive searches examine the working directory, and
nonrecursive searches read standard input.
