I have a problem when i try to create a log file from a daemon process using shell scripting in ubuntu 12. Ultimatly what i want to achieve is run a java/jar file from a script. After scourging the internet i found several solutions to do this, the one i choose is to create a startup script that calls a child script that contains all paramters required for the java program. From my startup script i run the following lines of code:
The DAEMON variable contains the script file that calls the actual java process with the following line:
Where $JAVA contains the location of the java command and the JAVA_ARGS are additonal arguments. If i call this daemon script directly and add the redirects to the java call everything works just as i would expect. But if i call the daemon script as a child script i do not get any results in my log file.
How can I redirect and append stdout and stderr to a file when using cron? Here is my crontab file:
*/5 * * * * /dir/php /dir/process_fns.php >>& /dir/dump.txt
Cron gives me an 'unexpected character found in line' when trying to add my crontab file.

So how can I to redirect... (5 Replies)
All,
Ok...so I know I *should* be able to control a process's stdin and stdout from the parent by creating pipes and then dup'ing them in the child. And, this works with all "normal" programs that I've tried. Unfortunately, I want to intercept the stdin/out of the scp application and it seems... (9 Replies)
Hi,
I would like to avoid re-directing line by line to a file.
What is the best way to re-direct STDOUT to a file in a subshell?
Thanks in advance.
Cheers

exec 2>>$SCRIPT_LOG_FILE
However, I've now discovered that the system used for automating the script executions... (4 Replies)

Dear Ann Landers,
This is about as bizarre as anything I've ever seen.
I have a little test script I've been working with. When I redirect stdout to a file, no file. Make a copy of the script to another name. Execute it and redirect stdout, and... (4 Replies)
