The crontab is trying to run a graphical application, but it gets run before the desktop is initialised, therefore the app fails. At this point the boot process stops, there is no PATH, there are no os variables, there are no shares, no smb no cifs, no nothing.
This is also the case with ssh, so when I login I have the prompt, but the os is completely dumb. I have to know where every command is on disk, and I don't.
So surely the easiest way around this is to know where the offending crontab file is, nano/vim and sudo. Without Sudo I can't do anything.
The jumper sounds interesting, os is Jessie based, or at least Debian based. I'll look into that now. Thanks.
Try logging in with ssh and typing this into the command prompt
Code:
PATH=/bin:/sbin:/usr/bin:/usr/sbin
export PATH
You should then be able to type in the commands without their full path names.
Hi again,

Hi Friends,
I don't understand why "a" is always being printed as zero, when I execute the following command.

Hello,
I have an ancient HP-UX 11.11 system where I have a logical volume marked stale and I can't get it sync'd. I have tried lvsync and lvreduce/lvextend to no avail. It is just one 4Mb PE on the disk that I can't get current.

Heyas
Just asking, is there a better to make sure the script will use the binary and not some alias?

Hi,
Below command works fine when we have other files apart from hello.txtls | ggrep -v hello* | xargs rm -rfBut, if there is only one file i.e hello.txt the rm command does not find anything to delete and the script hangs.
While there could be trivial ways to check using if conditions if... (6 Replies)

crontab
CRONTAB(1) General Commands Manual CRONTAB(1)NAME
crontab - maintain crontab files for individual users (V3)
SYNOPSIS
crontab [ -u user ] file
crontab [ -u user ] { -l | -r | -e }
DESCRIPTION
Crontab is the program used to install, deinstall or list the tables used to drive the cron(8) daemon in Vixie Cron. Each user can have
their own crontab, and though these are files in /var, they are not intended to be edited directly.
If the allow file exists, then you must be listed therein in order to be allowed to use this command. If the allow file does not exist but
the deny file does exist, then you must not be listed in the deny file in order to use this command. If neither of these files exists,
then depending on site-dependent configuration parameters, only the super user will be allowed to use this command, or all users will be
able to use this command.
If the -u option is given, it specifies the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines
"your" crontab, i.e., the crontab of the person executing the command. Note that su(8) can confuse crontab and that if you are running
inside of su(8) you should always use the -u option for safety's sake.
The first form of this command is used to install a new crontab from some named file or standard input if the pseudo-filename ``-'' is
given.
The -l option causes the current crontab to be displayed on standard output.
The -r option causes the current crontab to be removed.
The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables. After you exit
from the editor, the modified crontab will be installed automatically.

/etc/cron.allow
/etc/cron.deny
STANDARDS
The crontab command conforms to IEEE Std1003.2-1992 (``POSIX''). This new command syntax differs from previous versions of Vixie Cron, as
well as from the classic SVR3 syntax.
DIAGNOSTICS
A fairly informative usage message appears if you run it with a bad command line.
