Operating Systems Linux Red Hat Script not working if crontab scheduled Post 302887111 by sea on Wednesday 5th of February 2014 05:05:36 PM

If the script shown is executed by cron, be sure to use full path to applications inside the script..
Eg: /usr/bin/sudo, /usr/bin/sed, just like you had done for psql using the $dir_nnm_psg..
For egrep i'd alias it like:
Code:
alias egrep="/usr/bin/grep -e"

Hth

EDIT:
Also, if you need to enter the password for sudo, it wont work at all, as there is no "input box" or 'terminal' shown to the user, never (afaik).
Further, sudo executes the command as root, so why not execute the script as root directly in the first place?

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)
