Shell Programming and Scripting

hello guys am totally new to this script programming so help me
i want to write a script that obtain a particular day and schedule a task that day at particular time .. my problem is i don't know to get time and particular day in script ...

2.
how i ll print the time taken by executing a command in shell script


#. how i ll check that letter is in small casr or in capital case

plz let me know this

thankx

To check letter if its capital or small:

Code:

#! /bin/ksh
letter=A
if [[ $letter == [a-z] ]]; then
    echo "small"
else
    echo "CAPITAL"
fi

Date stamp:

format:
#!/bin/ksh

DAY=`date +%y%m%d`

When you echo $DAY, the output is 060726

When you want to add a TIMESONE to your DAY stamp, you will need to do the following:

first, on command line type the command "date"...This will show you your time zone

In you DAY string, change it to the following:
DAY=`TZ=GMT date +%y%m%d`

Now you can start playing around with the DAY parameter...You can go ahead a day or two, or backwards....

example:
DAY=`TZ=GMT+24 date +%y%m%d`

Output:
060725

The + will take you back....If you specify a -, it will take you forward...
