Thanks in advance. Have a nice weekend.

Note: Have a nice weekend should be in the same line not in the next line.

Code:

awk 's{print s}{s=$0}END{print s, "Have a nice weekend."}' ABC

Thanks Franklin,

Your code is working fine if I type the same. I need to modify slightl;y for my requirement. I have changed as below. This is working without any errors but required result is not displayed. My code is as follows

I have created s shell script for this and it looks as follows

Code:

#!bin/ksh
C=`/usr/ucb/sum firstfile'
awk 's{print s}{s=$0}END{print s, $C}' firstfile

This script is executing fine but the file is not getting appended. Please help.

Code:

#!/bin/ksh

C='/usr/ucb/sum firstfile'

awk -v var=$C 's{print s}{s=$0}END{print s, var}' firstfile

BTW: The shebang should be #!/bin/ksh

Through sed..

Code:

#!/bin/ksh
c='Have a great day'
sed '$s/$/ '"$c"'/' inputfile

Thanks All,

@Michael,

Your code is perfect. But the file is not getting saved with the newly written content. How can I save that file?

Thanks,
Rajesh
