fgrep
[options
] [pattern
] [files
]
Search one or more
files
for lines that match a literal, text-string
pattern
. Because
fgrep
does not support regular expressions, it is faster than
grep
(hence
fgrep
, for fast
grep
). Exit status is 0 if any lines match, 1 if not, and 2 for errors. See also
egrep
and
grep
.
Precede each line with its block number.
Print only a count of matched lines.
pat
Use this if pattern
pat
begins with - .
file
Take a list of patterns from
file
.
Print matched lines but not filenames (inverse of -l ).
Ignore uppercase and lowercase distinctions.
List filenames but not matched lines.
Print lines and their line numbers.
Silent mode: print only error messages, and return the exit status.
Print all lines that
don't
match
pattern
.
Print lines only if
pattern
matches the entire line.
Print lines in
file
that don't contain any spaces:
fgrep -v ' '
file
Print lines in
file
that contain the words in
spell_list
:
fgrep -f spell_list
