Print help message
-V, --version
Print version info
-v, --verbose
Print verbosely while processing
-q, --quiet
Only print fatal erros and requested output
-s, --silent
Alias of --quiet
-9, --format=TYPE
compile expressions to TYPE automata
Regexp selection and interpretation:
-E, --extended-regexp
PATTERN is an extended regular expression (ERE)
-F, --fixed-strings
PATTERN is a set of newline-separated fixed strings
-G, --basic-regexp
PATTERN is a basic regular expression (BRE)
-P, --perl-regexp
PATTERN is a Perl regular expression
-X, --xerox-regexp
PATTERN is a Xerox regulare expression
-e, --regexp=PATTERN
use PATTERN for matching
-f, --file=FILE
obtain PATTERN from FILE
-I, --ignore-case
ignore case distinctions
-w, --word-regexp
force PATTERN to match only whole words
-x, --line-regexp
force PATTERN to match only whole lines
-z, --null-data
a data line ends in 0 byte, not newline
Miscellaneous options:
--no-messages
suppress error messages
--invert-match
select non-matching lines
Output control:
-m, --max-count=NUM
stop after NUM matches\n -b, --byte-offset print the
byte offset with output lines
-n, --line-number
print line number with output lines
--line-buffered
flush output on every line
-H, --with-filename
print the filename for each match
-h, --no-filename
suppress the prefixing filename on output
--label=LABEL
print LABEL as filename for standard input
-o, --only-matching
show only the part of a line matching PATTERN
--binary-files=TYPE
assume that binary files are TYPE; TYPE is `binary', `text', or
`without-match'
-a, --text
equivalent to --binary-files=text
-d, --directories=ACTION
how to handle directories; ACTION is `read', `recurse', or
`skip'
-D, --devices=ACTION
how to handle devices, FIFOs and sockets; ACTION is `read' or
`skip'
-R, -r, --recursive
equivalent to --directories=recurse
--include=FILE_PATTERN
search only files that match FILE_PATTERN
--exclude=FILE_PATTERN
skip files and directories matching FILE_PATTERN
--exclude-from=FILE
skip files matching any file pattern from FILE
--exclude-dir=PATTERN
directories that match PATTERN will be skipped
-L, --files-without-match
print only names of FILEs containing no match
-l, --files-with-matches
print only names of FILEs containing matches
-c, --count
print only a count of matching lines per FILE
-T, --initial-tab
make tabs line up (if needed)
-Z, --null
print 0 byte after FILE name
Context control:
-B, --before-context=NUM
print NUM lines of leading context
-A, --after-context=NUM
print NUM lines of trailing context
-C, --context=NUM
print NUM lines of output context
--color[=WHEN],
--colour[=WHEN]
use markers to highlight the matching strings; WHEN is `always',
`never', or `auto'
-U, --binary
do not strip CR characters at EOL (MSDOS)
-u, --unix-byte-offsets
report offsets as if CRs were not there (MSDOS)
