A shell script to auto-update Chimera Web Browsers
Chimera's Navigator is having nightly builds released lately, so I wrote a shell script to grab it, mount the image, backup the old, copy the new one over, and rename the disk image file to the current date.

Read the rest of the article for the script...

The script should run fine without any modifications on any OS X 10.1.4 install. Commented lines are how I have it set up on my system. Change the cd line near the beginning to change where the script saves stuff.

#! /bin/sh

/bin/echo "Beginning Chimera Nightly Download: `date`"
/bin/echo "Changing to download folder"
cd $HOME
#cd $HOME/Downloads/Chimera
/bin/echo "pwd is: `pwd`"

/bin/echo "Downloading Chimera: `date`"

/usr/bin/curl -O
#/usr/local/bin/wget -c

if [ -f Chimera.dmg.gz ];then

/usr/bin/gunzip Chimera.dmg.gz

# /bin/echo "Converting Chimera DMG: `date`"
# /usr/bin/hdiutil convert -format UDZO -o temp.dmg Chimera.dmg
# /bin/rm Chimera.dmg
# /bin/mv temp.dmg Chimera.dmg

/bin/echo "Mounting Chimera DMG: `date`"
thedisk=`/usr/bin/hdid Chimera.dmg | /usr/bin/awk '{print $1}' | /usr/bin/head -n1`

/bin/echo "Testing to see if Chimera is running."
/bin/ps -xa | /usr/bin/grep Navigator | /usr/bin/grep -v grep > /dev/null

if [ $? -eq 0 ]
/bin/echo "Getting Chimera PID"
killme=`/bin/ps -xa | /usr/bin/grep Navigator | /usr/bin/grep -v grep | /usr/bin/cut -c1-5`
/bin/echo "Killing Chimera"
/bin/kill $killme
/bin/echo "Chimera not running"

/bin/echo "Backing up old Chimera"
/usr/bin/tar -czf /Applications/NavOld.tar.gz /Applications/

/bin/echo "Removing old Chimera"
/bin/rm -rf /Applications/

/bin/echo "Copying Chimera Application: `date`"
# /usr/local/sbin/CpMac -r "/Volumes/Chimera/" "/Applications/"
/usr/bin/ditto "/Volumes/Chimera/" "/Applications/"

/bin/echo "Ejecting Chimera DMG: `date`"
/usr/bin/hdiutil eject $thedisk

/bin/echo "Renaming Chimera DMG"

if [ -f "Chimera.dmg" ]; then
thedate=`/bin/date +%D | /usr/bin/tr "/" "-"`
/bin/mv -f "Chimera.dmg" "Chimera.$thedate.dmg"
/bin/echo "Renamed to Chimera.$thedate.dmg"

/bin/echo "End Chimera download: `date`"

[Editor's note: I tested this and it works perfectly. The only caveat is to also change the path where the script looks for "Navigator" if you don't have it installed at the top level of the default Applications folder.]

no luck
Authored by: loren_ryter on Jun 03, '02 10:11:15AM

i'm no shell script expert by i couldn't get this to work properly....

i wanted the download directory to be "/Volumes/Scratch/Downloads/Chimera/" and I wanted the target directory to be "/Applications (OS X)/Internet/Browsers/"... I tried to change the relevant strings. I put quotes around all the path strings (replaced "/Applications/" with my target path string.)

but what I got was:

1. chimera .dmg downloaded to ~ directory

2. a "Contents" folder in the target directory with no application but all the resources.

I put quotes around all the path strings (replaced "/Applications/" with my target path string.)

Maybe someone can re-rewite this with a variable target path? and explain why the download would wind up in my home directory rather than the specified download directory?

in the line that copys the new Chimera to your application folder, just add "" to the path of your application directory, and it will work, no matter what folder you want your app to be copied to.

/usr/bin/ditto "/Volumes/Chimera/" "/your/path/"

instead of
/usr/bin/ditto "/Volumes/Chimera/" "/Applications/"

Personally the "ditto" command did not copy the navigator app accross, rather its Contents folder. You can instead use this command....

/Developer/Tools/CpMac -r "/Volumes/Chimera/" "/Applications/"

Assuming you have devtools installed.

I goofed
Authored by: THEM on Jun 03, '02 04:11:04PM

I goofed in the ditto line, remove the so you have
/usr/bin/ditto "/Volumes/Chimera/" "/Applications/"

That will copy it properly. I dislike ditto.

Authored by: loren_ryter on Jun 03, '02 10:24:07PM

hmm... now everything worked except Navigator is not copied over to the target directory.

When I tried manually using the same commands on the command line, i get permission errors.... and i take it "cpmac" is a command you can install with fink? i have fink, but "fink install CpMac" finds nothing.

[12-228-142-249:~] lryter% ditto "/volumes/chimera/" "/Applications (OS X)/Internet/browsers/"
./.Trashes/: Permission denied
[12-228-142-249:~] lryter% /usr/local/sbin/CpMac -r "/Volumes/Chimera/" "/Applications (OS X)/Internet/browsers/"
/usr/local/sbin/CpMac: Command not found.

ignore above
Authored by: loren_ryter on Jun 03, '02 10:34:10PM

sorry ... don't know how to delete postings here. but i got it working with the suggestion of someone in a reply to my original thread.

ditto had to include, so you had to have

ditto "/volumes/chimera/" "/targetvolume/targetdir/"

rather than:

ditto "/volumes/chimera/" "targetvolume/targetdir/"

'cp -Rp' is enough - doesn't ship with resource forks
Authored by: mblakele on Oct 27, '02 03:07:26PM

Chimera doesn't ship with resource forks, so this is sufficient:

cp -Rp /Volumes/$FILENAME/${APPNAME}.app /Applications/

of course, there's no guarantee that Chimera won't add resource forks some day... You can check for resource forks with:

find /Applications/ -print0 | perl -0ne 'chop; print "$_\n" if -s "$_/..namedfork/rsrc"'

Why doesn't curl work?
Authored by: ateles on Jun 05, '02 01:19:45PM

I ran this script and I couldn't get curl (or wget) to work. They returned (in curl's case):

curl: (5) Couldn't resolve proxy ''none''

so I replaced ftp by http in the curl line:

curl -O


curl -O

and that worked! Any idea why wouldn't work with ftp://....?
