  • OSX - Function to list all members for a given group

    Group membership in OS X is a mish-mash of standards that end up meaning there's almost a half-dozen of ways to belong to a group, what with group inheritance and automatic assignment. This means there's no easy command to find out all groups a user belongs to. The only sensible way then is to list all users and then query each user for membership. NOTE: This is a function. Once input you can execute it by calling with a groupname. Show Sample Output


    -1
    members () { dscl . -list /Users | while read user; do printf "$user "; dsmemberutil checkmembership -U "$user" -G "$*"; done | grep "is a member" | cut -d " " -f 1; };

  • List OSX applications and versions.

    Uses find, plutil and xpath. Note: Some applications don't have proper information. system_profiler might be better to use. It's a bit slow query. Due to command length limit, I removed -name "*.app" and CFBundleName. Show Sample Output


    -1
    find /Applications -type d -maxdepth 1 -exec sh -c 'echo "{}"; (plutil -convert xml1 -o - "{}/Contents/Info.plist" | xpath /dev/stdin "concat(\"v\", /plist/dict/string[preceding-sibling::key[1]=\"CFBundleShortVersionString\"]/node())" 2>/dev/null)' \;

  • Generate background office noise using Digg feeds and OSX.

    Instead of having someone else read you the Digg headlines, Have OSX do it. Requires Curl+Sed+Say. This could probably be easily modified to use espeak for Linux.


    -2
    IFS=`echo -en "\n\b"`; for i in $(curl http://feeds.digg.com/digg/container/technology/popular.rss | grep '<title>' | sed -e 's#<[^>]*>##g' | tail -n10); do echo $i; echo $i | sed 's/^/Did you hear about /g' | say; sleep 30; done

  • OSX: Use Say Command to Help You Play Hide-and-Seek

    Hide-and-Seek is one of the greatest games in the parent's arsenal. Your kid runs off and hides for several minutes, while waiting for you to find him/her. This gives you time to catch a breath and check your email without feeling like a loser. If you'd also like to take advantage of the counting time--claiming that thinking space as your own--use this command on your OSX terminal to maximize downtime. Also, if your kid is like mine, you can get away with "for i in {1..100};" :)


    -3
    txt="";for i in {1..20};do txt=$txt"$i. ";done;say $txt" Ready or not, here I come"

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

To get internet connection information .
To get the connection information of protocol tcp and extended infortmation.

Get your public ip using dyndns

Make .bashrc function to backup the data you changed last houres
The original overwrites any previous backups, and only saves exactly the last hours worth, but not 1 hour + 1 minute. This version creates or appends files, and backs up everything since the last backup (using the backups timestamp as the reference), plus it uses TMPDIR if set.

Install an mpkg from the command line on OSX
Installing most OSX apps is just a matter of dropping it in /Applications, either GUI-wise or with cp -r. However, many packages are distributed in "mpkg" format, and those have to be installed with an installer. If you don't want to go to the trouble of firing up VNC to install an mpkg, you can use the "installer" command. This will install an application from a .mpkg it to /Applications system-wide. To install a program for just one user, replace "-target /" with "-target username".

Text message on wallpaper
Display some text on the wallpaper especially warning messages

Get your outgoing IP address
should be very consistent cause it's google :-)

Display any tcp connections to apache
Sometimes apache will get stuck in an established state where you can't get a list of the connecting IP's from mod_status... not a good thing when you need to ban an abusive ip.

'hpc' in the box - starts a maximum of n compute commands modulo n controlled in parallel
the block of the loop is useful whenever you have huge junks of similar jobs, e.g., convert high res images to thumbnails, and make usage out of all the SMP power on your compute box without flooding the system. note: c is used as counter and the random sleep $ r=`echo $RANDOM%5 |bc`; echo "sleep $r"; sleep $r is just used as a dummy command.

Stay in the loop…
