![]() Third-party packages are available, e.g., CSWggrep from OpenCSW. Solaris grep (see manual) has no such feature. Warning: ‘-binary-files=text’ might output binary garbage, which can have nasty side effects if the output is a terminal and if the terminal driver interprets some of it as commands. If type is ‘text’, grep processes a binary file as if it were text this is equivalent to the -a option. If type is ‘without-match’, grep assumes that a binary file does not match this is equivalent to the -I option. When matching binary data, grep may treat non-text bytes as line terminators. By default, type is ‘binary’, and grep normally outputs either a one-line message saying that a binary file matches, or no message if there is no match. ![]() If a file's allocation metadata, or if its data read before a line is selected for output, indicate that the file contains binary data, assume that the file is of type type. Process a binary file as if it were text this is equivalent to the -binary-files=text option. $.q.The feature requested (see manual) is documented o, -only-matching Print only the matched (non-empty) parts of a matching line, with each such part on a separate. ^^Ġ001220: 0C24 E871 0B00 0083 F8FF 89C3 0F84 DF03. word file.bin to look up a text content ('word') and the few characters before it as a reminder: -a, -text Process a binary file as if it were text this is equivalent to the -binary-filestext option. xxd -u /usr/bin/xxd | grep 'DF'Ġ0017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003 we use an ORed regexp to search for ' DF' OR 'DF ' (the searchTarget preceded or followed by a space char). ![]() Note that using a simple search target like 'DF' will incorrectly match characters that span across byte boundaries, i.e. (standard input):00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003 found we could get usable results with xxd -u /usr/bin/xxd > /tmp/xxd.hex grep -H 'DF' /tmp/xxd (standard input):00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003 tried several things before arriving at an acceptable solution: xxd -u /usr/bin/xxd | grep 'DF' Here are some of the things I've tried since posting this: xxd -u /usr/bin/xxd | grep 'DF'Ġ0017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003 grep -ibH "df" /usr/bin/xxd Nice output, just what I want to see, but it just doesn't work for me in this situation.Į. Using xxd -u /usr/bin/xxd as an example I get a output that would be useful, but I cannot use that for searching. Using grep -b option doesnt seem to work either, I did try all the flags that seemed useful to my situation, and nothing worked.ĭ. I CAN force it through hexdump or something of the link but because its a stream it will not give me the offsets and filename that it found a match in.Ĭ. Problem is, when I try to search for hex values, I get the problem of if just not searching for the hex values, so if I search for 00 I should get like a million hits, because thats always the blankspace, but instead its searching for 00 as text, so in hex, 3030.ī. Which is the pretty well standard output I would normally get with grep -URbFo. I am anticipating (and expecting) something along the lines of: : It's a little hard to explain the output I am getting since I really am not getting any output. Perl COULD be a option, but at this point, I would assume my lack of knowledge with bash and its tools is the main culprit. I am aware of the what it changes to, and I can do the same process and compare the lists to see which match.
