Format
fgrep [Bbcilnqsvx]] [-W option[,option]...] [–e pattern] … [–f patternfile] … [pattern]
[file …file …]
Guideline: The fgrep utility
is fully supported for compatibility with older UNIX systems.
However, use grep –F instead because it
may provide greater functionality and is considered the standard for
portable UNIX applications as defined by POSIX.2 IEEE
standard 1003.2-1992.
