RudiC,

Thanks for your response.

I digged into this issue, the input files are coming from accurev SCM tool to my unix location. somehow it is removing the last line when it processes all the input files through this for loop and sed. But if i edit any file in vi mode before running my script and saving back after adding an empty line and removing it again (means no actual change to the file) and saving. now when i run the script, that particular file contents are good. It is not removing the last line now. My input files are with extension .txt, .cfg, .properties, .ksh.

As a workaround what i did is, added the below code which is adding an empty line at the end of all my input files before it hits the for loop and sed command.

Code:

for k in `cat $tmpfile`
do
echo >> $k
done

I know it is not actual fix. Still i added this to move ahead.

For your comments,
i can say, my input file call it as a.txt contain some variables with ~, say ~variableA~ in some places.

a.txt:

Code:

line1
line2
~variableA~
line4

my other file call it as b.txt, contains this list of variables with values, say
b.txt:

Code:

variableA=/proj/apps/sun
variableB=/tmp

For loop will read all variables in b.txt one by one, and go to other for loop to read all input files one by one, find replace the variables with values.

Let me know if anything else i can try. Thanks again.
