UNIX for Dummies Questions & Answers

Hi,

I will pass 3 parameters for a script.I have to check the file name and create a new file name with time stamp.

the parameters which i'm passing are

/dir/stg/filename.txt
/dir/path/head.txt
/dir/path/tail.txt

Now i have to check filename like :

if it is a.txt i have to create a_`date '+%Y%m%d_%H%M%S'`.txt

if it is b.txt the new file should be b_`date '+%Y%m%d_%H%M%S'`.txt

How can we do this with in a script.

Thanks in advance!

Code:

!#/bin/ksh
datedfilename()
{
       filename=`basename $1`
       file=${filename%%.*}
       echo "$file`date '+%Y%m%d_%H%M%S'`.txt"
}

newfile1=$( datedfilename $1)
newfile2=$( datedfilename $2)
newfile3=$( datedfilename $3)

Hi,

I have to check the variable(a.txt) passed for the script and then create new file with timestamp.
