Top Forums Shell Programming and Scripting Crontab is not working in printf Post 302758985 by MadeInGermany on Monday 21st of January 2013 06:41:30 AM

The % character has a special meaning in crontab entries.
Code:
man crontab
...

You need to escape each % as \%;
'text1%text2' becomes 'text1'\%'text2' and "text3%text4" becomes "text3"\%"text4" (i.e. two strings with a \% in between).
Code:
printf '%s -> %s\n' "$(date '+%Y-%m-%d %H:%M')" ...

becomes
Code:
printf \%'s -> '\%'s\n' "$(date '+'\%'Y-'\%'m-'\%'d '\%'H:'\%'M')" ...

This is so ugly that you better put the original code in an executable script, and run the script from the crontab.

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
chkconfig(8), ntsysv(8), systemd(1), systemctl(8), systemd.service(5) Jan 2006 service(8)
