Hi
I want to insert the record to the beginning of the file not to the end of the file.
If we run operator >>, it appends the record to the end of the file.
Example: Suppose file ‘A’ contains following records
Day 10
Day 20
Day 30
If I run print ‘Day 5’ >> A, file ‘A’ will have records as follows
Day 10
Day 20
Day 30
Day 5
But I want the file ‘A’ should have records in the following order
Day 5
Day 10
Day 20
Day 30.
Could some one please tell me how to achieve this?

Thanks and Regards
Chinmaya

You can achieve this by this script:
#name of the script: addline
#how to use: addline fileA "Day 5"
echo $2 > tempfile
cat $1 >> tempfile
mv tempfile $1
