redirect standard output to file in CRON

[JonathanHolliday]

I have a script that runs a program with an interactive user parameters screen.

In order to run this as a CRON job 'we' have created a script that passes the key depressions to the job.

The trouble is the CRON job is "blind" so any on-screen messages that may have occured during an interactive run are not seen.

Is there a script statement to redirect output to a log file instead of the default of screen?

Script example:

$TRADERDIR/bin/jvint -k6 > /dev/null << INPUT
^?


B001
B001
$FROMDAY
$TODAY
S
U
N
pospost
^[[H^?^[[F

INPUT

(jvint6 -k6 is the program to run & INPUT is the parameters to enter, including control characters).

Thanks,

Jonathan

I wonder whether running strings on the log file afterwards will make the output any easier to decipher:

strings your.log > your_new.log

might do it.

this sounds like a job for expect, as far as sending input to the cron job. Try the tee program for sending all output to a file, either that or possibly run it with nohup, as that sends STDOUT to a logfile by default
