NAME
  socprint.sh - POSIX™-compliant, zero-dependency shell script to print in NUS SoC

SYPNOSIS
  socprint.sh (p|print) [options] <username> <printqueue> [-|<filepath>]
  socprint.sh (j|jobs ) [options] <username> <printqueue>
  socprint.sh (l|list ) [options] <username>
  socprint.sh (h|help )

QUICKSTART
  To print a file instantly, copy and paste the following line into your shell:
  curl -s https://raw.githubusercontent.com/dlqs/SOCprint/master/socprint.sh | sh -s -- print <username> <printqueue> <filepath>

  Alternatively, use the hosted version at https://socprint.xyz

DESCRIPTION
  This script requires a POSIX™-compliant sh, a sunfire account, and connection to
  SoC wifi.

  Besides the above, this script has zero-dependencies, is portable, and handles text/byte streams. This makes printing
  in SoC a painless, non-ass-sucking experience that doesn't require installing any drivers.

COMMANDS (shortname|longname)
  (p|print) Print a file at specified printqueue.
  (j|jobs ) List jobs at specified printqueue.
  (l|list ) List all printqueues.
  (h|help ) Show this message.

OPTIONS
  <username>
    Sunfire username, without the @sunfire.comp.nus.edu.sg part.

  <printqueue>
    Printer + suffix. See PRINTQUEUES for commonly-used printers.

  [-|<filepath>]
    Print file. Recommended PDF/text. Undefined behaviour for other file types.
    If unspecified or -, read from standard input.

  -i, --identity-file <filepath>
    (optional) Additional identity file to use with ssh. Skip if you already set
    up sunfire identity files for ssh.

  -2
    (optional) Prints every two logical pages onto one physical page.
    Can only be used for pdf files that have portrait orientation.

  --dry-run
    (for debugging/tests) Echoes commands to be executed without executing them.

EXAMPLES
  To print from filepath:
    ./socprint.sh print d-lee psc008-dx ~/d/cs3210_tutorial8.pdf

  To combine with curl and the pipe operator:
    curl -s https://www.comp.nus.edu.sg/~ooibc/bxtree.pdf | ./socprint.sh print d-lee psc008-dx

  To print with shortname, using the redirection operator:
    ./socprint.sh p d-lee psc008-dx < ~/d/cs3210_tutorial8.pdf

  To check jobs:
    ./socprint.sh jobs d-lee psc008-dx

  To list printqueues:
    ./socprint.sh list d-lee

  To download and run from any directory:
    sudo curl https://raw.githubusercontent.com/dlqs/SOCprint/master/socprint.sh -o /usr/local/bin/socprint.sh
    sudo chmod 755 /usr/local/bin/socprint.sh

IMPLEMENTATION
  Roughly speaking, the print command will:
  1. Login to sunfire using ssh.
     You will be prompted for your password, unless your identity files are set up.
     This script *does not* save/record your password.
  2. Copy the file into your home directory in sunfire, to a temporary file.
  3. Submit your job to the printqueue.
  4. List the printqueue. You job *should* appear. If not, something has gone wrong.
  5. Remove the temporary file.

STANDARDS
  This script targets conformance to POSIX.1-2017 standards (https://pubs.opengroup.org/onlinepubs/9699919799/).
  Yes, you read that right and no, we're not kidding. POSIX™ compliance is serious enterprise business!!!1
