I am running script with cron each 1 minute. I have problem with this script after start or reboot. In script i have some as:
#!/bin/sh
IP="127.0.0.1"
PORT="16000"
nc $IP $PORT > /tmp/test.log
if [ -s /tmp/test.log ]; then
...
else
...
fi
exit 0
Script does not work well after reboot/start of system - /tmp/test.log is still empty (it is test for running cc*am). After cron stop/start manualy from telnet it begins work well. Are scripts in crontab limited, or what i have wrong ?

hmm, it seems, Netcat (nc) does not work from cron.

cron runs a rather limited environment, often PATH and HOME are not set, so best is to run a script that sets all environments it needs.

tried. PATH , Home are set. but nc (netcat-nc) does not run.
Tried run it with whole path , no error message - nothing message.

Solved. I forgot, that line must be:
nc $IP $PORT \&2> /tmp/test.log
nc $IP $PORT \&2> /tmp/test.log
