crontab not working ? [solved]

[cwc]

I'm trying to scan my network with the following crontab?

I type crontab -e and edit the file to test for every minute:
* * * * * /bin/bash /home/cwc/bash/logfile.sh


This is the script I'm trying to run and it works just using command line:
#!/bin/sh
NOW=$(date +"%Y-%m-%d-%S");
LOGFILE="log-$NOW.txt";
nmap -sP 192.168.1.0/24 > /home/cwc/html/logs/$LOGFILE;

Is cron daemon started ?

Off-topic, but :

Is the script executable?
Is $PATH provided for your script? (try #! /bin/bash -l )

Looks like you're running systemd. That rather cryptic message means that you can't use the initd scripts on such a system. You need to use systemctl to control the services and units. It does seem that your cron daemon stops after running your job once. You should probably investigate if it keeps running when you remove certain jobs.

Thanks for the lines:
Ya . I'm one of the evil ones running systemd

# systemctl | grep cronie
cronie.service loaded active running Command Scheduler


Here's what I have:

[cwc]

some how things are now working:
#crontab -e
*/5 * * * * /bin/bash -l /home/cwc/bash/makelogs.s

/5 works better.

Here is my script:

NOW=$(date +"%Y-%m-%d-%s");
LOGFILE="log-$NOW.txt";
nmap -sP 192.168.1.0/24 >> /home/cwc/html/logs/$LOGFILE;


I am not 100% sure what bash -l does though.

I don't understand this:
/bin/bash -l /home/cwc/bash/makelogs.sh

From man bash

-l Make bash act as if it had been invoked as a login shell (see INVOCATION below).

A login shell is one whose first character of argument zero is a -, or one started with the --login option.


I'd appreciate an explanation.
Thanks for all the help.

Now another question?
Why the EOF

Redirect uses it.
