Guys
do you know any other command that will insert a line at particular line number...I used this one...but it is not working if the above lines are blank.

This command will put "name=cat.abc.com at 11th line.But if there is no line 10 the command is not working...

sed '10a\ name = cat.abc.com' con.txt


Really appreciate if you guys can help me out with this...alll i need is a command to put lines (append or insert) at particular line number...

Thanks alot

you may pass a var into SED to indicate the line number

sed $line'a\
insert line
' filename

tried ur solution like this...


line=10
sed $line'a\ insert_line con.txt

But getting some errors...
sed: can't read line: No such file or directory

Any suggestions...

Thanks for the code man..its working...but only at the prompt..its not really changing the file...so

I tried awk 'NR==11{print "new line"}1' file>file2.

But using "file2" is not a feasible solution for me..The change has to happen in "file" itself.

do u know a solution that doesnt use file2.Please let me know.

You should check the man page for your sed:

if file has less than 10 lines i don't think you can add 11th line to it..
you can try this to add text above any line you want
