Script não roda no crontab? [ RESOLVIDO]

[bruno contin]

escrevi um escript:
#!/bin/bash
#
./gbak -t -g -l /home/teksystem/dados/dadosmc.fdb /home/teksystem/dados/dadosmc.fbk -user SYSDBA -pass masterkey

DATA=`date +%a_%H`
# Dados do arquivo de backup
MAQUINA="panan"
ARQUIVO="backup-$MAQUINA-$DATA.tar.gz"
DIRETORIOS="/home/teksystem/dados"
# Cria o arquivo .tar.gz no /tmp (Temporario)
cd /tmp
find $DIRETORIOS -mtime -1 -type f -print |
tar zcf /tmp/$ARQUIVO -T -
# Acessa o FTP e coloca os arquivos
mv $ARQUIVO /opt/backup

# Remove os arquivos temporarios
rm -rf /tmp/$ARQUIVO


que coloquei no diretório do firebird
para ser executado a 12:00 meio dia e as 21:30 as nove e trinta da noite
só que ele não está sendo executado.
script:

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

Não faltou algo nas últimas duas linhas entre o comando cd e a chamada da rotina?

Eu deixaria assim (alterações em negrito):

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
