Execute a shell script everyday at specific time

You want to edit your crontab file using

crontab -e

Then you want to add

55 23 * * * COMMAND TO BE EXECUTED

for more info look at this


I'm anything, but a linux expert, but a quick Google search conjured up this:

watch -n <your time> <your command/script>

This should do the trick. For more information, check this out: http://www.linfo.org/watch.html


To add a crontab job, type the following command at a UNIX/Linux shell prompt:

$ sudo crontab -e

Add the following line:

1 2 3 4 5 /path/to/script

where

1: Minutes (0-59)
2: Hours (0-23)
3: Days (1-31)
4: Month (1-12)
5: Day of the week(1-7)
/path/to/script - your own shell script

In your case it would be:

55 23 * * * /path/to/yourShellScript
