I have written this script. This is used for creating a backup folder.
Code:
#!/bin/sh
#set -x
. /home/.profile
usage="Usage is $0"
usage="$usage [-b <dir>]"
# Use the getopt utility to set up the command line flags.
set -- `/usr/bin/getopt b: $*`
# Process individual command line arguments
while [ $1 != -- ]; do
case $1 in
-b) dir=$2
shift
;;
esac
shift
done
MYSQLBACKUP=`which mysqlbackup`
if [ "$backup_dir" == "" ];then
datedir=`date +"%Y%m%d"`
backupdir=/home/back
$MYSQLBACKUP --defaults-file=$INSTANCE_HOME/my.cnf --backup-dir=$backupdir/$datedir --compress backup
if [ $? -eq 0 ]; then
start_lsn=`grep -E 'start_lsn' variables.txt`
end_lsn=`grep -E 'end_lsn' variables.txt`
exit 1
else
echo " [`date +%Y\-%m\-%d\ %H\:%M\:%S`] [ERROR] Backup Failed. Please check"
echo "backup failed." |mailx -s "full backup failed." abc.com
fi
fi
The problem is that even when the command is executing without any error it is pring the commands in the success block (when if is true) but it is also printing the commands in the unsuccessfull block (else condition) too.
any suggestions?

backup_interactive
BACKUP_INTERACTIVE(8) AFS Command Reference BACKUP_INTERACTIVE(8)NAME
backup_interactive - Enters interactive mode
SYNOPSIS
backup [interactive] [-localauth] [-cell <cell name>]
[-help]
backup [i] [-l] [-c <cell name>] [-h]
DESCRIPTION
The backup interactive initiates an interactive session for issuing backup commands. As indicated in the syntax statement, the operation
code (interactive) is optional.
Several features of interactive mode distinguish it from regular mode:
o In interactive mode, the "backup"> prompt replaces the system (shell) prompt. The operator enters only a command's operation code
(omitting the command suite name, backup).
o If the -localauth flag or the -cell argument is included on the backup interactive command, the settings apply to all commands issued
during that interactive session. The issuer does not need to type them on every command. Another consequence is that the flag and
argument do not appear in the syntax statement generated by the help subcommand or -help flag on an individual command issued at the
"backup"> prompt.
o The backup jobs and backup kill commands are available only in interactive mode. It is not possible to track and terminate backup
operations as cleanly in non-interactive mode.
o It is not necessary to enclose strings that include metacharacters in double quotes or other delimiters.
o The backup command interpreter establishes a connection to the Backup Server, Volume Server and Volume Location (VL) Server processes
as it enters interactive mode, and uses the same connection for all commands during the session. Execution time can therefore be faster
than in non-interactive mode, in which the command interpreter must establish a new connection for each command.
To exit an interactive session, issue the backup quit command.
OPTIONS -localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to
the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more
details, see backup(8).
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).
-help
Prints the online help for this command. All other valid options are ignored.
EXAMPLES
The following example shows how the -localauth flag and -cell argument do not appear when the help dump subcommand is issued in interactive
mode.
% backup
backup> help dump
dump: start dump
Usage: dump [-volumeset <volume set name>] [-dump <dump level name>]
[-portoffset <TC port offset>] [-at <Date/time to start dump>+]
[-append ] [-n ] [-file <load file>] [-help ]
PRIVILEGE REQUIRED
None. However, backup commands that require privilege in regular mode still require it in interactive mode.
