  • 'hpc' in the shell - starts a maximum of n compute commands modulo n controlled in parallel, using make

    this oneliner uses make and it's jobserver for parallel execution of your script. The '-j' flag for make defines number of subprocesses to launch, '-f' tells make use stdin instead of Makefile. Also make have neat flag '-l', which "Specifies that no new jobs (commands) should be started if there are others jobs running and the load is at least load (a floating-point number)." Also you can use plain Makefile, for better readability: targets = $(subst .png,.jpg,$(wildcard *.png)) (targets): echo convert $(subst .jpg,.png,$@) $@ all : $(targets)


    5
    echo -n 'targets = $(subst .png,.jpg,$(wildcard *.png))\n$(targets):\n convert $(subst .jpg,.png,$@) $@ \nall : $(targets)' | make -j 4 -f - all

  • Makefile argument passing

    This would allow reference of $(VAR) (if defined) with the value 'foobar' within the Makefile.

  • Debug your makefile

    Say your dependencies specified in your Makefile (or dates on your source files) is causing 'make' to skip some source-files (that it should not) or on the other other end, if it is causing make to always build some source-files regardless of dates of target, then above command is handy to find out what 'make' thinks of your date v/s target date-wise or what dependencies are in make's view-point. The egrep part removes the extra noise, that you might want to avoid. Show Sample Output


    1
    make -d | egrep --color -i '(considering|older|newer|remake)'

  • compile source & then remove the dev tools you needed to install

    on a dpkg managed system this PATTERN will help you generate .deb files from source AND remove all the dev libs you had to install. i hate cluttering up my machine with rouge packages and headers. it would be pretty darn easy on rpm systems as well. i just dont have a rpm managed system to test on right now. NOTE, you sharp ones will notice that it uninstalls the deb you just made! yeah, but the deb is still there to do with it what you want, like re install it. or you can just grep -v after the diff

    dpkg-query -l > 1.lst; sudo apt-get install -y build-essential; ./configure; make; sudo checkinstall -D make install; dpkg-query --list > 2.lst; diff 1.lst 2.lst | grep '^>' | awk '{print $3}' | xargs sudo apt-get remove -y --purge

Pack up some files into a tarball on a remote server without writing to the local filesystem
I recently found myself with a filesystem I couldn't write to and a bunch of files I had to get the hell out of dodge, preferably not one at a time. This command makes it possible to pack a bunch of files into a single archive and write it to a remote server.

PRINT LINE the width of screen or specified using any char including Colors, Escapes and metachars
One of the first functions programmers learn is how to print a line. This is my 100% bash builtin function to do it, which makes it as optimal as a function can be. The COLUMNS environment variable is also set by bash (including bash resetting its value when you resize your term) so its very efficient. I like pretty-output in my shells and have experimented with several ways to output a line the width of the screen using a minimal amount of code. This is like version 9,000 lol. This function is what I use, though when using colors or other terminal features I create separate functions that call this one, since this is the lowest level type of function. It might be better named printl(), but since I use it so much it's more optimal to have the name contain less chars (both for my programming and for the internal workings). If you do use terminal escapes this will reset to default. $ tput sgr0 For implementation ideas, check my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html

Quickly display a string as Qr Code

Create POSIX tar archive
tar(1) and cpio(1) are not fully platform agnostic, although their file formats are specified in POSIX.1-2001. As such, GNU tar(1) might not be able to extract a BSD tar(1) archive, and ivce versa. pax(1) is defined in POSIX.1-2001. To extract an archive: $ pax -rf archive.tar

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"
