Commands tagged locate (13)

  • To start, you first need to make sure updatedb has been run/updatedb, and initialized the db: su -l root -c updatedb This locate command is provided through the mlocate package, installed by default on most GNU/Linux distributions. It's available on the BSDs as well. Not sure about support for proprietary UNIX systems. The output is self-explanatory- it provides an overview of how many directories and files are on your system. Show Sample Output

    locate -S

  • Catches .swp, .swo, .swn, etc. If you have access to lsof, it'll give you more compressed output and show you the associated terminals (e.g., pts/5, which you could then use 'w' to figure out where it's originating from): lsof | grep '\.sw.$' If you have swp files turned off, you can do something like: ps x | grep '[g,v]im', but it won't tell you about files open in buffers, via :e [file]. Show Sample Output

    vim -r 2>&1 | grep '\.sw.' -A 5 | grep 'still running' -B 5

  • The wherepath function will search all the directories in your PATH and print a unique list of locations in the order they are first found in the PATH. (PATH often has redundant entries.) It will automatically use your 'ls' alias if you have one or you can hardcode your favorite 'ls' options in the function to get a long listing or color output for example. Alternatives: 'whereis' only searches certain fixed locations. 'which -a' searches all the directories in your path but prints duplicates. 'locate' is great but isn't installed everywhere (and it's often too verbose). Show Sample Output

    function wherepath () { for DIR in `echo $PATH | tr ":" "\n" | awk '!x[$0]++ {print $0}'`; do ls ${DIR}/$1 2>/dev/null; done }

  • MAC OSX doesn't come with a locate command, This will do the same thing as the locate command on a typical Linux OS. Simply add it to your ~/.bash_profile

    alias locate='if [ $((`date +%s`-`eval $(stat -s /var/db/locate.database); echo $st_mtime`)) -gt 3600 ]; then echo "locate: db is too old!">/dev/stderr; sudo /usr/libexec/locate.updatedb; fi; locate -i'

  • Find all books on my systems and move them into folder. The -0 switches are to handle spaces etc. in the filenames. Why would you need this? Locate uses an index, so it's super quick, and xargs is more elegant than a for loop.

    locate -0 -i *barthes* | xargs -0 mv -t ~/'Library/Books/Barthes, Roland'

    locate searchstring | xargs grep foo

Extract audio from Mythtv recording to Rockbox iPod using ffmpeg
There are some pretty good live performances on late night TV. With Mythtv I record David Letterman, Jimmy Fallon, and Conan nightly all in HD from over the air broadcasts. If I find a live performance I like I copy it to my Rockboxed iPod using this command. The Rockbox firmware knows how to downmix 5.1 audio. The command above extracts the audio from the video starting at 58 minutes and 15 seconds. It ends at the end of the file since this was the last performance of the recording. The command creates an ac3 file. I copy the ac3 file to my Rockbox iPod and rock on.

log rm commands
Sometimes, it is annoying to find your files or directories missing. If you want to log all the rm commands you can put this in /etc/profile.
