what does < < mean in the shell

- by stib

when looping recursively through folders with files containing spaces the shell script I use is of this form, copied from the internet: while IFS= read -r -d $'\0' file; do dosomethingwith "$file" # do something with each file done < <(find /bar -name *foo* -print0) I think I understand he IFS bit, but I don't understand what the < < characters mean. Obviously there's some sort of piping going on here.. It's very hard to google "< <", you see. TIA -stib

zip being too nice (osX)

- by stib

I use zip to do a regular backup of a local directory onto a remote machine. They don't believe in things like rsync here, so it's the best I can do (?). Here's the script I use echo $(date)>>~/backuplog.txt; if [[ -e /Volumes/backup/ ]]; then cd /Volumes/Non-RAID_Storage/; for file in projects/*; do nice -n 10 zip -vru9 /Volumes/backup/nonRaidStorage.backup.zip "$file" 2>&1 | grep -v "zip info: local extra (21 bytes)">>~/backuplog.txt; done; else echo "backup volume not mounted">>~/backuplog.txt; fi this all works fine, except that zip never uses much CPU, so it seems to be taking longer than it should. It never seems to get above 5%. I tried making it nice -20 but that didn't make any difference. Is it just the network or disc speeds bottlenecking the process or am I doing something wrong?

help with Outlook Exchange server and curl

- by stib

I work on a mac in a building full of PCs, and the IT department here doesn't have IMAP access turned on on the exchange servers. So I miss a lot of meetings because I don't get reminders because I access my mail via Outlook Web access. I had written a script to scrape my Outlook Web Access calendar and turn it into iCal format, so I could get my reminders via thunderbird or iCal.app. It basically downloaded the calendar page via curl, parsed the HTML and reformatted all the appointments as ical. it wasn't elegant, but it worked. Then they changed to outlook 2007, and it doesn't work any more. I have a sketchy knowledge of curl, and almost zero knowledge of how outlook works. Can anyone point me towards a reference for getting calendar info out of an exchange server without using outlook? If I can configure curl to get the HTML I will be happy, but if there's a more elegant way, such as getting the calendar info as XML I'll be delirious.

modify the way files get opened from finder by shift-clicking (etc) as in windows

- by stib

In the windows shell it is possible to modify the default action for opening any document type when holding down a modifier key such as shift or option when double clicking. So for example I can open a jpeg in irfanview if I just double click it, in firefox if I shift-double click it or in potatoshop if I option-double click it. However on a mac I have to right click, and choose "open with..", which can be annoying when there are a lot of possible candidates (such as with jpegs) or if I want to open the file with somehting like an applescript, which won't show up on the list and will have to be found in the file system and specified manually, every.. single.. time. Is there a way of making the mac open files differently by holding down modifier keys when double clicking?

Computer name not appearing on network

- by stib

I can connect to other computers on my home network (ubuntu + OSX machines) using the IP address, but I can't connect using the netbios name. On the mac the name appears in Finder but if I try to connect (goconnect to server smb://[email protected]) it doesn't work, while smb://[email protected] does. Same with ssh, ping and afp between the macs. This is a intermittent problem. It has worked in the past.

Is there a way to start a Linux machine automatically?

- by stib

On Mac machines the user can schedule the machine to power-on automatically, is there anything for Linux that gives us the same ability? I can schedule shut downs whenever I want, it's powering up that I want to do.

Applescript studio - how do I get every control in a window

- by stib

I'm trying to enable or disable all the control in a window as the programme changes from interactive to non-interactive mode. How can I ask a window to give me all its contents? every control of window "mainWindow" doesn't work, nor does contents of window "mainWindow" Actually, I haven't been able to find any good documentation for interacting with menu items from interface builder at all. Things like how to set the contents of popups, and buttons and so on. thanks
