$ webgrep --help usage: webgrep [OPTION]... PATTERN [URL]... Search for PATTERN in each input URL and its related resources (images, scripts and style sheets). By default, - resources are NOT downloaded - response HTTP headers are NOT included in grepping ; use '--include-headers' - PATTERN is a basic regular expression (BRE) ; use '-E' for extended (ERE) Important note: webgrep does not handle recursion (in other words, it does not spider additional web pages). Examples: webgrep example http://www.example.com # will only grep on HTML code webgrep -r example http://www.example.com # will only grep on LOCAL images, ... webgrep -R example http://www.example.com # will only grep on ALL images, ... Regexp selection and interpretation: -e REGEXP, --regexp REGEXP use PATTERN for matching -f FILE, --file FILE obtain PATTERN from FILE -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 -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: -s, --no-messages suppress error messages -v, --invert-match select non-matching lines -V, --version print version information and exit --help display this help and exit --verbose verbose mode --keep-files keep temporary files in the temporary directory --temp-dir TMP define the temporary directory (default: /tmp/webgrep) Output control: -m NUM, --max-count NUM stop after NUM matches -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 file name for each match -h, --no-filename suppress the file name prefix on output --label LABEL use LABEL as the standard input filename prefix -o, --only-matching show only the part of a line matching PATTERN -q, --quiet, --silent suppress all normal output --binary-files TYPE assume that binary files are TYPE; TYPE is 'binary', 'text', or 'without-match' -a, --text equivalent to --binary-files=text -I equivalent to --binary-files=without-match -L, --files-without-match print only names of FILEs containing no match -l, --files-with-match 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 NUM, --before-context NUM print NUM lines of leading context -A NUM, --after-context NUM print NUM lines of trailing context -C NUM, --context NUM print NUM lines of output context Web options: -r, --local-resources also grep local resources (same-origin) -R, --all-resources also grep all resources (even non-same-origin) --include-headers also grep HTTP headers --cookie COOKIE use a session cookie in the HTTP headers --referer REFERER provide the referer in the HTTP headers Proxy settings (by default, system proxy settings are used): -d, --disable-proxy manually disable proxy --http-proxy HTTP manually set the HTTP proxy --https-proxy HTTPS manually set the HTTPS proxy Please report bugs on GitHub: https://github.com/dhondta/webgrep
