  • Finder compresses to ZIP but always includes extraneous metadata files (__MACOSX and .DS_Store) files and folders that may confuse other programs. One alternative is creating them and then editing the ZIP. This can work standalone or in an automator script accepting multiple selections (files or folders) and creating one zip per argument/selected file without that metada.

    echo "$@" for f in "$@"; do FILENAME=${f##*/};FILEPATH=${f%/*}; cd "${FILEPATH}"; zip -r "${f}".zip "${FILENAME}" -x "*.DS_Store" -x "__MACOSX"; done; afplay /System/Library/Sounds/Sosumi.aiff

  • 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

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

View the newest xkcd comic.
This function displays the latest comic from One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic. To get a random xkcd comic, I also use the following: $xkcdrandom(){ wget -qO-|tee >(feh $(grep -Po '(?

Convert .flv to .avi

send substituted text to a command without echo, pipe
zsh only - This avoids the need for echo "message" | which creates an entire subshell. Also, the text you are most likely to edit is at the very end of the line, which, in my opinion, makes it slightly easier to edit.

open a seperate konsole tab and ssh to each of N servers (konsole 4.2+)
creates a new tab for each of N servers in listofservers.txt and ssh's to said servers then, try the "send to all sessions" feature of konsole to do the same work on all servers at the same time. BIG time saver, but be careful!
