By default, it uses the tcz format compatible with tinycore.\\n\\n pox supports 3 archive formats:\\n 1) squashfs (default): The tcz is a squashfs. This requires mksquashfs.\\n 2) zip\\n 3) elf+zip: Self-extracting.\\n\\nOptions:\\n create|c: create the TCZ file.\\n verbose|d: verbose\\n file|f FILE: file name (default /tmp/pox.tcz)\\n run|r: Runs the first non-flag argument to pox. Remaining arguments will\\n be passed to the program. Use '--' before any flag-like arguments\\n to prevent pox from interpretting the flags.\\n self|s: Create a self-extracting elf. This implies -z.\\n zip|z: Use zip and unzip instead of a loopback mounted squashfs. Be sure\\n to use -z for both creation and running, or not at all.\\n For convenience and testing, you can create and run a pox in one command.\\n\\nExample:\\n $ pox -c /bin/bash /bin/cat /bin/ls /etc/hosts\\n Will build a squashfs, which will be /tmp/pox.tcz\\n\\n $ sudo pox -r /bin/bash\\n Will drop you into the /tmp/pox.tcz running bash\\n You can use ls and cat on /etc/hosts.\\n\\n Simpler example, with arguments:\\n $ sudo pox -r /bin/ls -- -la\\n will run `ls -la` and exit.\\n\\n $ sudo pox -r -- /bin/ls -la\\n Syntactically easier: the program name can come after '--'\\n\\n $ sudo pox -c -r /bin/bash\\n Create a pox with a bash and run it.\\n\\n $ pox -cvsf date /bin/date\\n Creates a self-executing pox called \\\"date\\\".\\n $ ./date --utc\\n\\nNotes:\\n - When running a pox, you likely need sudo to chroot\\n\\n - Binaries run out of a chroot often need files you are unaware of. For\\n instance, if bash can't find terminfo files, it won't know to handle\\n backspaces properly. (They occur, but are not shown). To fix this, pass\\n pox all of the files you need. For bash: `find /lib/terminfo -type f`.\\n\\n - Other programs rely on helper functions, such as '/bin/man'. If your\\n program has built-in help commands that trigger man pages, e.g. \\\"git\\n help foo\\\", you'll want to include /bin/man too. But you'll also need\\n everything that man uses, such as /etc/manpath.config. My advice: skip\\n it.\\n\\n - When adding all files in a directory, the easiest thing to do is:\\n `find $DIR -type f` (Note the ticks: this is a bash command execution).\\n\\n - When creating a pox with an executable with shared libraries that are\\n not installed on your system, such as for a project installed in your\\n home directory, run pox from the installation prefix directory, such\\n that the lib/ and bin/ are in pox's working directory. Pox will strip\\n its working directory from the paths of the files it builds. Having bin/\\n in the root of the pox file helps with PATH lookups, and not having the\\n full path from your machine in the pox file makes it easier to extract a\\n pox file to /usr/local/.\\n\\n - pox is not a security boundary. chroot is well known to have holes.\\n Pox is about enabling execution. Don't expect it to \\\"wall things off\\\".\\n In fact, we mount /dev, /proc, and /sys; and you can add more things.\\n Commands run under pox are just as dangerous as anything else.\",\"printenv\":\"Print environment variables.\\n\\nSynopsis:\\n printenv\",\"ps\":\"Print process information.\\n\\nSynopsis:\\n ps [-Aaex] [aux]\\n\\nDescription:\\n ps reads the /proc filesystem and prints nice things about what it\\n finds. /proc in linux has grown by a process of Evilution, so it's\\n messy.\\n\\nOptions:\\n -A: select all processes.
