Did you read the man page?

Code:

man date

The synopsis of the command is this:

Code:

date [OPTION]... [+FORMAT]

The formats are extensive, but these 2 do what you request:

Code:

%k     hour ( 0..23)
%l     hour ( 1..12)

Thats 24-hour and 12-hour, respectively. Thus:

Code:

[scuzzy@slackdell /home/scuzzy]$ date
Tue Jan 31 05:38:17 EST 2006
[scuzzy@slackdell /home/scuzzy]$ date +%k
 5
[scuzzy@slackdell /home/scuzzy]$ date +%l
 5
[scuzzy@slackdell /home/scuzzy]$

So the bash script would look like this:

Code:

#!/bin/sh
hour=`date +%k`
let "hour += 1"
echo "hour is $hour"

...is that right?

Code:

echo "hour is $((`date '+%k'` + 1 ))"
