Shell Programming and Scripting

Hi @ all

i made a very little shell script witch is working well when i'm launching it directly

like with ./script

but when i'm launching it by cron tab it work at half only.

the part of the script witch are not working are:

Code:

#!/bin/sh

apt-get updade
apt-get -s upgrade >> /var/log/upgrade.log 2>&1

when i'm launching this "by hand" it's working well and i have the result in the log file, but when i would start the script b a crontab the log file is empty

is someone have an idea ?

the second thing is i'm launching (by cron always) another script in background.
the script is working well and do his job but the output redirecting in a file not. The file stay empty too.

I'm using this sentence: (it's in a php file launched by crontab)

Code:

system("the_file_path/script.sh >>/var/log/my_log.log 2>&1 &");

also if someone have an idea, or a way to prospect i'll be happy

thanks

It might not be related but shouldn't you replace 2&1 by 2>&1?

it had misstyped the forum's thread there is 2>&1 in the scripts (i correct the 1rts post)

thanks for your answer

i also tryed with others reidrecting args in the past, but same result.

like

Code:

apt-get -s upgrade &> /var/log/mylog.log

Well I remember I had once a problem with the crontab because I was not using absolute paths like /usr/bin/apt-get.
Maybe the redirection is not a problem?
Maybe the program is not executed at all?

yesss thanks, so logic it works thanks a lot.

i just have to found why the second part is not writing anything.

Code:

system("the_file_path/script.sh >>/var/log/my_log.log 2>&1 &");

it was just a right acces isssue :s
the script was launched by a user who does'nt have acess to var log
