  • This is an example of the usage of pdfnup (you can find it in the 'pdfjam' package). With this command you can save ink/toner and paper (and thus trees!) when you print a pdf. This tools are very configurable, and you can make also 2x2, 3x2, 2x3 layouts, and more (the limit is your fantasy and the resolution of the printer :-) You must have installed pdfjam, pdflatex, and the LaTeX pdfpages package in your box.

  • If the pdf/dvi/etc documentation for a latex package is already part of your local texmf tree, then texdoc will find and display it for you. If the documentation is not available on your system, it will bring up the package's webpage at CTAN to help you investigate. Show Sample Output

  • It is often recommended to enclose capital letters in a BibTeX file in braces, so the letters will not be transformed to lower case, when imported from LaTeX. This is an attempt to apply this rule to a BibTeX database file. DO NOT USE sed '...' input.bib > input.bib as it will empty the file! How it works: /^\s*[^@%]/ Apply the search-and-replace rule to lines that start (^) with zero or more white spaces (\s*), followed by any character ([...]) that is *NOT* a "@" or a "%" (^@%). s=<some stuff>=<other stuff>=g Search (s) for some stuff and replace by other stuff. Do that globally (g) for all matches in each processed line. \([A-Z][A-Z]*\)\([^}A-Z]\|},$\) Matches at least one uppercase letter ([A-Z][A-Z]*) followed by a character that is EITHER not "}" and not a capital letter ([^}A-Z]) OR (|) it actually IS a "}", which is followed by "," at the end of the line ($). Putting regular expressions in escaped parentheses (\( and \), respectively) allows to dereference the matched string later. {\1}\2 Replace the matched string by "{", followed by part 1 of the matched string (\1), followed by "}", followed by the second part of the matched string (\2). I tried this with GNU sed, only, version 4.2.1. Show Sample Output

    sed '/^\s*[^@%]/s=\([A-Z][A-Z]*\)\([^}A-Z]\|},$\)={\1}\2=g' literature.bib > output.bib

  • LaTeX is not a smart compiler - You need to run it several times to make it back-patch all the missing refs. The message if to do so or not is buried in its endless output and the log file. This grep lines helps to find it.

  • kpsewhich is a tool for path and file lookup. It is a front-end of the kpathsea library. For one or more given package or file names it returns the complete path from within the TeX installation, that one which the compiler would actually use. Via backticks we can use it as argument to less, more, or any editor. For example: gedit `kpsewhich hyperref.sty` Show Sample Output

    less `kpsewhich scrartcl.cls`

  • Uses zsh globbing syntax to safely remove all the files known to be generated by LaTeX, but only if there is actually a .tex source file with the same basename present. So we don't accidentally delete a .nav .log or .out file that has nothing to do with LaTeX, e/'[[ -f ${REPLY:r}.tex ]]'/ actually checks for the existance of a .tex file of the same name, beforehand. A different way to do this, would be to glob all *.tex files and generate a globbing pattern from them: TEXTEMPFILES=(*.tex(.N:s/%tex/'(log|toc|aux|nav|snm|out|tex.backup|bbl|blg|bib.backup|vrb|lof|lot|hd|idx)(.N)'/)) ; rm -v ${~TEXTEMPFILES} or, you could use purge() from grml-etc-core ( http://github.com/grml/grml-etc-core/blob/master/usr_share_grml/zsh/functions/purge )

    rm -v *.(log|toc|aux|nav|snm|out|tex.backup|bbl|blg|bib.backup|vrb|lof|lot|hd|idx)(.e/'[[ -f ${REPLY:r}.tex ]]'/)

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

convert video format to youtube flv format

Uniquely (sort of) color text so you can see changes
Colorify colors input by converting the text to a number and then performing modulo 7 on it. This resulting number is used as the color escape code. This can be used to color the results of commands with complex outputs (like "482279054165371") so if any of the digits change, there's a good chance the color will change too. I say good chance because there's only 7 unique colors here, so assuming you were watching random numbers, there would be a 6/7 chance that the color would change when the number changed. This should really only be used to help quickly identify when things change, but should not be the only thing relied upon to positively assert that an output has not changed.

Create a script of the last executed command
Sometimes commands are long, but useful, so it's helpful to be able to make them permanent without having to retype them. An alternative could use the history command, and a cut/sed line that works on your platform. $history -1 | cut -c 7- > foo.sh

Who has the most Apache connections.
This will tell you who has the most Apache connections by IP (replace IPHERE with the actual IP you wish to check). Or if you wish, remove | grep -c IPHERE for the full list.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Retrieve "last modified" timestamp of web resource in UTC seconds
This command line assumes that "${url}" is the URL of the web resource. It can be useful to check the "freshness" of a download URL before a GET request.

Clear terminal Screen
Probably the quickest / easiest way to clear the screen.

Convert spaces in file names to underscores

Count lines of code across multiple file types, sorted by least amount of code to greatest
Gives you a nice quick summary of how many lines each of your files is comprised of. (In this example, we just check .c, .h, .php and .pl). Since we just use wc -l to count, you'll just get a very rough estimate of how many lines of actual code there are. Use a more sophisticated algorithm instead if you need to.

Doing some floating point calculations with rounding (e.g. at the 3rd decimal)
