Miscellaneous Downloads

• Unix basics
• vi/vim basics
• LaTeX exam template (configurable, conditional sections, conditional inclusion)
• LaTeX template for course reports
• pfmt: filter to start each sentence on a new line; C source - Linux Binary.
  Modified version of original by Justin Zobel.
  Hint: The following lines added to your vimrc file will apply pfmt to the current paragraph:

  		" : Format the paragraph using pfmt
  		 map  vip:!pfmt}j
  		imap  vip:!pfmt}j
  		

• LaTeX scripts to generate a variety of files.
  Example: to create PDF files of Beamer presentation slides, call: lx2pdfslides -o beamer -o bib -o gv -o pdf -o pdfslides -f <input tex file name>
  Note that these need to be updated to reflect the bin directory you place the files in - I place them in ~saied/bin - change this to your own settings.
• Individual scripts; calling the script without any arguments will display a help message on syntax:

  lxprocess	main script, called by other scripts; calling this with no arguments clears intermediate log and auxiliary files.
  lx2dvi	create a DVI file
  lx2pdf	create a PDF file
  lx2pdfslides	create a PDF file of LaTeX slides
  lx2ps	create a PostScript (PS) file
  lx2psa3	create an A3 PostScript file (useful for posters)
  lx_process_log.sh	process error messages for Vim.
  lxviw	create and display DVI
  lxviwr	create and display DVI, resolve cross-references
  lxviws	create and display DVI, use for slides

• Download all scripts as one tarball: LaTeXScripts.tgz
• Sample PostScript File to help you understand how to edit PostScript. Open the file in an editor.
• C++ code to extract required tuples or tables from a MySQL dump file
  (On Linux/Unix, compile using g++ -O3 -o mysqldump_extract mysqldump_extract.cpp)
• My Vim configuration file
  (Hacked/copied/plagiarised from numerous sources - thanks!)
  Useful key bindings:

  F1	Save
  F2	format paragraph with each new sentence on a new line (useful when editing long LaTeX documents). This calls Justin Zobel's 'pfmt' program (described above)
  F3	toggle paste mode; this makes pasting text with the mouse really easy.
  F4	Compile the current file (C, LaTeX): For C code, if you use etags first, vim will jump directly to the file/line with the error. Same for LaTeX, but a bit more tricky. For a LaTeX file, this key processes the file and displays it in xdvi (use Shift-F4 to resolve cross-references)
  F5	Comment/uncomment current line (using // comment character for C/PHP/LaTeX, and # by default
  F11	toggle list mode (show non-printing characters)
  F12	toggle highlight search mode
  \sh	Spellcheck: fast, no-fuss highlighting of possible errors.
  \sc	Spellcheck: clear error highlighting.
  \si	Spellcheck: interactive spellcheck
  \sa	Spellcheck: add current word to dictionary
  ,~	insert a linefull of the character '~' (good for breaking up sections in documents, code).
  ,/	as above, using character '/'
  ,%	as above, using character '%'

  It's also got a lot of settings like autoindent, automatic insertion of comment characters for multi-line comments etc. that are probably best left untouched.
• Script to backup recently-modified files to a remote host over ssh
  1. set up automatic ssh authentication from source host to backup host
  2. call from crontab as:

     				# Hourly, daily, weekly, and monthly snapshots
     				01  *  *  *   * $HOME/bin/snapshot 61 minutes >> /var/log/crontab.log
     				10 01  *  *   * $HOME/bin/snapshot  1 days    >> /var/log/crontab.log
     				20 02  *  * sun $HOME/bin/snapshot  8 days    >> /var/log/crontab.log
     				30 03 01  *   * $HOME/bin/snapshot 32 days    >> /var/log/crontab.log
