NAME

hfst-grep - =Search for PATTERN in each FILE or standard input.

SYNOPSIS

hfst-grep [ OPTIONS ...] PATTERN [ FILE ...]

DESCRIPTION

Search for PATTERN in each FILE or standard input. Pattern is, by default, a Xerox regular expression (XRE). Example: hfst-grep ’h e l l o % w o r l d’ menu.h menu.c

Common options:

-h , --help

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)
