[gentoo-user] hwclock: command not found

[Joseph]

I'm updating clock via bash script. When I run it from a command line, it works just fine but when I try to run it via crontab I get:

/home/thelma/business/programs/time_date_setting_script.sh: line 3: hwclock: command not found

here the script:
#!/bin/sh
rdate -s 128.138.140.44
hwclock --systohc

and crontab entry:
45 12 * * 1 sh /home/thelma/business/programs/time_date_setting_script.sh

When I run the scrip manually or just the command: "hwclock --systohc" it is working OK; why isn't it working from the crontab?

I've noticed that cron doesn't have /sbin and /usr/sbin in PATH. Try
using the absolute path to hwclock.

Could it be that cron doesn't have this command on its PATH? Might be
best to put the full path to hwclock instead of just "hwclock".

That was it, thank you.

With a recent upgrade of fcron, I ran into this problem (and solved it
by switching to absolute paths). From fcron's changelog:

* don't inherit fcron's environment when running a job but build
the environment from scratch (cleaner, and this is what Vixie
cron does)

I have no idea how the environment is built from scratch, but for me
anything run from the system crontab now has $PATH /usr/bin:/bin
