fgrep - search a file for a character string
SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
ffffggggrrrreeeepppp [options] string [file ...]
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
_f_g_r_e_p (fast _g_r_e_p) searches files for a character string and prints all
lines that contain that string. _f_g_r_e_p is different from _g_r_e_p(_1) and
_e_g_r_e_p(_1) because it searches for a string, instead of searching for a
pattern that matches an expression. It uses a fast and compact
algorithm.
The characters $$$$, ****, [[[[, ^^^^, |, ((((, )))), and \\\\ are interpreted literally by
_f_g_r_e_p, that is, _f_g_r_e_p does not recognize full regular expressions as does
_e_g_r_e_p. Since these characters have special meaning to the shell, it is
safest to enclose the entire _s_t_r_i_n_g in single quotes ''''...''''.
If no files are specified, _f_g_r_e_p assumes standard input. Normally, each
line found is copied to the standard output. The file name is printed
before each line found if there is more than one input file.
Command line options are:
----bbbb Precede each line by the block number on which it was found. This
can be useful in locating block numbers by context (blocks are 512
bytes long and number from 0).
----cccc Print only a count of the lines that contain the pattern.
----iiii Ignore upper/lower case distinction during comparisons.
----llll Print the names of files with matching lines once, separated by
new-lines. Does not repeat the names of files when the pattern is
found more than once.
----nnnn Precede each line by its line number in the file (first line is 1).
----ssss Silent mode. No pattern matches or error messages are printed.
This option allows command expressions to check _f_g_r_e_p's exit status
without having to deal with output.
----vvvv Print all lines except those that contain the pattern.
----xxxx Print only lines matched entirely.
----eeee _s_p_e_c_i_a_l__s_t_r_i_n_g
Search for a _s_p_e_c_i_a_l _s_t_r_i_n_g (_s_t_r_i_n_g begins with a ----).
----ffff _f_i_l_e
Take the list of _s_t_r_i_n_g_s from _f_i_l_e.

Exit status is 0 if any matches are found, 1 if none, 2 for syntax errors
or inaccessible files (even if matches were found).

Ideally there should be only one _g_r_e_p command, but there is not a single
algorithm that spans a wide enough range of space-time tradeoffs. Lines
are limited to BUFSIZ characters; longer lines are truncated. BUFSIZ is
defined in ////uuuussssrrrr////iiiinnnncccclllluuuuddddeeee////ssssttttddddiiiioooo....hhhh.
