Output Script Result to Log

[OffHand]

Hi there,

Is there a way to write the results of the script below to a log file?

The script is made for OS X but I will probably be able to figure out how to do it once I know the Linux way.

Thanks in advance!

#!/bin/bash

# this should find all users currently logged in 
users=( `who | awk '{print $1}' | sed '/^root$/d' | uniq` )

for user in "${users[@]}"; do
    # find the homedir
    homedir=/Users/$user
    find $homedir/Library/Caches -name "*AdobeFnt*" -delete
done

./script.sh > my.log

[OffHand]

./script.sh > my.log

OS X moved from Cron to Launchd. Basically the command is put in a xml plist which looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Label</key>
	<string>ClearFontCache</string>
	<key>ProgramArguments</key>
	<array>
		<string>sh</string>
		<string>/Library/ITScripts/clean_font_cache.sh</string>
	</array>
	<key>RunAtLoad</key>
	<true/>
</dict>
</plist>

Should I change

<string>/Library/ITScripts/clean_font_cache.sh</string>

to

<string>/Library/ITScripts/clean_font_cache.sh > my.log</string>

?

Tried it but that does not work. Is there a way to put it in the script itself instead of the command?

I finally managed to make the script write to a log file but unfortunately the file is empty. This should be easy to fix. I have added "echo >> /home/user/testlog.txt" to the script like posted below.

[code]
#!/bin/bash

# this should find all users currently logged in
users=( `who | awk '{print $1}' | sed '/^root$/d' | uniq` )

for user in "${users[@]}"; do
# find the homedir
homedir=/Users/$user
find $homedir/Library/Caches -name "*AdobeFnt*" -delete
echo >> /home/user/testlog.txt
done

#!/bin/bash

# this should find all users currently logged in 
users=( `who | awk '{print $1}' | sed '/^root$/d' | uniq` )

for user in "${users[@]}"; do
    # find the homedir
    homedir=/Users/$user
    find $homedir/Library/Caches -name "*AdobeFnt*" -delete >> /home/user/testlog.txt
done

echo >> bla puts a newline into the file and nothing else. so append the >> to the find command, if you want the output of find to be in the file.

For some reason that generates an empty log file even though the files were deleted

Edit: I assume that there is nothing to log because the files that were found are already deleted. It would be great though if it could log what has been deleted.

Any ideas?

All you need to do is sit back, relax and allow someone else's code do it for you by the mere use of the commandline option -fprint:

find $homedir/Library/Caches -name "*AdobeFnt*" -fprint logfile -delete

Building on ABCC's suggestion, you can also print some more descriptive messages like this. This will also not truncate the logfile each run.

#!/bin/bash

# this should find all users currently logged in
users=( `who | awk '{print $1}' | sed '/^root$/d' | uniq` )

for user in "${users[@]}"; do
  # find the homedir
  homedir=/Users/$user
  find $homedir/Library/Caches -name "*AdobeFnt*" -printf "`date`: Removing %p\n" -delete
done >> /home/user/testlog.txt

I'll try that tomorrow and let you know. Thanks!
