  1. A PCAP-based tool that allows you to specify an extended regular or hexadecimal expression to match against data payloads of packets. It understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw, across a wide variety of interface types, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

  2. Open Source collab' done right!

    See comment threads between authors of ag (The Silver Searcher) & ripgrep ;-)

  3. Useful when you don't want to pull the LibreOffice suite:

    $ unzip -qc "$1" ppt/slides/slide*.xml | grep -oP '(?<=&lt;a:t&gt;).*?(?=&lt;/a:t&gt;)'

  4. Super-fast and efficient file searching tool, also quite convenient when it comes to its options ;-)

  5. 1for i in $(find /usr/lib -type f -name '*.so.*'); do
    2      nm -D $i | grep MY_SYMBOL;
    3      [[ $? -eq 0 ]] && echo $i;
    4done
