  • 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. Show Sample Output

    pdfnup --nup 2x1 --frame true --landscape --outfile output.pdf input.pdf

  • 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

    texdoc packagename

  • 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.

    egrep "(There were undefined references|Rerun to get (cross-references|the bars) right)" texfile.log

  • 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 ( )

    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? 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.

Share Your Commands

Check These Out

renames multiple files that match the pattern
Useful when you want to quickly rename a bunch of files.

exec chmod to subfiles
Using `-exec cmd {} +` causes find to build the command using all matching filenames before execution, rather than once per file.

Find files that were modified by a given command
This has helped me numerous times trying to find either log files or tmp files that get created after execution of a command. And really eye opening as to how active a given process really is. Play around with -anewer, -cnewer & -newerXY

Cut the first 'N' characters of a line
Saves one character, the original is probably clearer

Remove blank lines

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

ls -qahlSr # list all files in size order - largest last
I find it useful, when cleaning up deleting unwanted files to make more space, to list in size order so I can delete the largest first. Note that using "q" shows files with non-printing characters in name. In this sample output (above), I found two copies of the same iso file both of which are immediate "delete candidates" for me.

Execute a command on logout
Execute a command on shell logout,and run it until is finished,then shell is closed.

Found how how much memory in kB $PID is occupying in Linux
The "proportional set size" is probably the closest representation of how much active memory a process is using in the Linux virtual memory stack. This number should also closely represent the %mem found in ps(1), htop(1), and other utilities.

vim's pastetoggle: when you press f9 'paste' is on , press f9 again and 'paste' is off, and so forth (works in insert-mode and command-mode)

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
