Linux script 2

[kzn]

Hi I am running Centos 6.4 and would appreciate any pointers with regards to the following.
I have set up a cron job to run a script file every day. The script is as follows: mysqldump -u root -ptest123 conversis >> /root/backup.txt

Basically all I am trying to achieve is for a backup to be created daily but I do not want it to over write the previous days back up. In an ideal situation the following would happen:
backup1.txt
backup2.txt
.
.
backup30.txt

and then it would start the cycle again and over write backup1.txt once it reached backup30.txt.

Any ideas or pointers appreciated.

Thank you,

Hi

If that 1..~30 number can match the current month's day, then just use [tt]date[/tt] :

33 3 * * * mysqldump -u root -ptest123 conversis >> "/root/backup$( date +'%d' ).txt"

( Note that I usually forget ( this time I remembered just because the previous forgetting was yesterday in thread822-1711114 ) that [url

]percent sign ( % ) has special meaning[/url] in certain Cron implementation. You may have to escape it. My Dillon's Cron needs no such escaping. )
