Apr 26th, 2006

Hello, good afternoon.

Im a newby user writing my first shell script, and i trying to make it run with the cron utility.

If i run this code manually, the code was sucefull runned, but, when i put in this task in the crontab, the mail dont cant sended.

When i write a ps command, my task look like this:



root      2647  0.0  0.0  1584  640 ?        S    18:35   0:00 CROND

root      2648  0.0  0.0  2128  932 ?        S    18:35   0:00 /bin/bash -c /root/rmssProject/./rmmsConnection.sh

smmsp     2650  0.0  0.0     0    0 ?        Z    18:35   0:00 /usr/sbin/sendmail -FCronDaemon -i -odi -oem root

root      3317  0.0  0.0  1796  500 ?        S    18:38   0:00 sleep 2s

...and the mail cant sended. the process stay in stand by, and i dont now why, the cron cant process my script.

The uname command showme this:

Linux host.example.com 2.4.21-9.0.1.ELsmp #1 SMP Mon Feb 9 22:26:51 EST 2004 i686 i686 i386 GNU/Linux

And my code is this:

# Mail subject

SUBJECT="IP'S state"

# to mail's

EMAIL_LIST="ayudamicro@hotmail.com"



ssh script@xxx.xxx.xxx.xxx < outCommand.ptx | cat > listPop.pop

grep -i '^[a-z][0-9{3}\-][0-9{6}|a-f{6}]' listPop.pop > listCleanPop.pop

LINE=$(wc -l listCleanPop.pop | gawk '/[0-9]+ +*/ {print $1;}')

while test "$LINE" = "0";

do

        ssh script@65.200.191.232 < outCommand.ptx | cat > listPop.pop

        sleep 2s

        grep -i '^[a-z][0-9{3}\-][0-9{6}|a-f{6}]' listaPop.pop > listcleanPop.pop

        LINE=$(wc -l listaCleanPop.pop | gawk '/[0-9]+ +*/ {print $1;}')

done

sort listCleanPop.pop > listNewPop.pop

diff listNewPop.pop listBeforePop.pop > diferPop.pop

sed -e "s/^\([0-9]*\)a[0-9]*/The line \1 was added/" diferPop.pop |

sed -e "s/^\([0-9]*\)c[0-9]*/The line \1 was changed/" |

sed -e "s/^\([0-9]*\)d[0-9]*/The line \1 dont stay or was deleted/" |

sed -e "s/^\([0-9]*,[0-9]*\)a[0-9]*/The lines \1 was added/" |

sed -e "s/^\([0-9]*,[0-9]*\)c[0-9]*/The lines \1 was changed/" |

sed -e "s/^\([0-9]*,[0-9]*\)d[0-9]*/The lines \1 dont stay or was deleted/" | cat > mailBodyPop.pop

LINE=$(wc -l mailBodyPop.pop | gawk '/[0-9]+ +*/ {print $1;}')

if test "$LINE" = "0"; then

        echo "No changes" | mail -s "$SUBJECT" "$EMAIL_LIST"

else

        cp -f listNewPop.pop listBeforePop.pop

        cat mailBodyPop.pop | /usr/sbin/sendmail -oi -s "$SUBJECT" "$EMAIL_LIST"

Finally i can solve my problem.
I added the FULL PATH for the commands and my own files. These solve the problem.
