+===== blobutils =====
+Tools to manipulate binary data in Unix, because it was a nightmare.
+They are not fast (written in shell and Python), I usually need to convert only several bytes, so it does not matter.
+http://jenda.hrach.eu/gitweb/?p=blobutils;a=summary
+Terms: bin: raw binary data; bits: ascii '0' and '1'; hex: ascii hexdump
+blbgrep: grep binary file
+<code>
+> blbgrep data.bin 04 ee 04 7e
+data.bin:<offset>
+</code>
+blbinhex: hexdump (binary to hexa)
+blbithex: bits to hex
+<code>
+> echo 1110 0011 | blbithex
+E3
+</code>
+blcstruct: unpack C structure, e.g. "blcstruct f" unpacks array of floats
+blhexbin: hex to binary
+blhexbit: hex to bits
+blhexbitmap: hex to black and white image (e.g. adafruit gfx format)
+<code>
+echo 22 54 54 78 42 | blhexbitmap
+██ ███ █
+█ █ █ ██
+█ █ █ ██
+█    ███
+█ ████ █
+</code>
+blhexflip: interactive binary editor
+blhexrev: no idea
+blrev: MSB to LSB format
+blxor: 64bit xor (used heavily during implementation of A5/1 cracker)
+dechex, dechex: base convert
+gp.sh: 1D data plot. First column is label, second value. Parameter is filename.
+<code>
+echo -e "bla -7.247 \nble 3.28 \nfoo 0.3 \nxx 1" | gp.sh my_numbers
+</code>
+gr-pack, gr-unpack: convert binary to gnuradio bytes and back
+itemize: add line numbers (I did not know about nl command back then)
+sum.sh: sum numbers, one per line
+<code>
+echo -e "-7.247 \n 3.28 \n 0.3 \n 1" | sum.sh
+-2.667
+</code>
+udate: unix timestamp to human-readable date
