crontab jobs aren't running


hello,

i'm having trouble getting cron to work; none of the jobs seem to run. cron is running background after bootup. platform is Debian, which as far as i can tell isn't too different from cron on other distros.

3 entries
Code:
mm@al:~$ crontab -l
37 4 * * * date +%y%m%d
3,13,23,33,43,53 * * * * wget -O "/home/mm/data/`date +%r`"\ radar.gif http://www.meteoschweiz.ch/data/radsat/radar.gif >/dev/null 2>&1
* * * * * xcalc

a debugging attempt:

Code:
strace -f -p 1397 -o /tmp/asdfj

al:/home/mm# cat /tmp/asdfj  | grep -i xcalc
2145  execve("/bin/sh", ["/bin/sh", "-c", "xcalc"], [/* 4 vars */]) = 0
2145  stat64("/usr/bin/xcalc", 0xbffffb00) = -1 ENOENT (No such file or directory)
2145  stat64("/bin/xcalc", 0xbffffb00)  = -1 ENOENT (No such file or directory)
2145  write(2, "/bin/sh: xcalc: command not foun"..., 34 <unfinished ...>
2144  <... read resumed> "/bin/sh: xcalc: command not foun"..., 4096) = 34
any pointers?

PATH Setting

Hi,

When running under cron the profile and .bash_profile are not run.
Try calling file executables with the full path name (fully qualified name)

ah, that's good to know.

i updated crontab accordingly; here's the new trace output

Code:
al:/home/mm# cat /tmp/asdfj  | grep -i xcalc
2679  execve("/bin/sh", ["/bin/sh", "-c", "/usr/bin/X11/xcalc"], [/* 4 vars */]) = 0
2679  execve("/usr/bin/X11/xcalc", ["/usr/bin/X11/xcalc"], [/* 7 vars */]) = 0

those errors are gone,
but i don't see any xcalc apps run
