Hi I have a script on Solaris 5.6 to restart cron /etc/init.d/cron. I have trouble restarting cron. It's all beacuse of the line:
pid=`/usr/bin/ps -e | /usr/bin/grep cron | /usr/bin/sed -e 's/^ *//' -e 's/ .*//'`
which returns not null. This is because of the system return two process which are belong to:
/etc/init.d/cron
/usr/bin/grep cron
Dows any one know how to fix this problem.

case $1 in
'start')
echo "$pid";

then
/usr/bin/rm -f /etc/cron.d/FIFO

shells
shells(4) File Formats shells(4)NAME
shells - shell database
SYNOPSIS
/etc/shells
DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.
A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines
which search the file. Blank lines are also ignored.
The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
/bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh,
/usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.
Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).
