Hello All,

Could you please provide the solution to my following query
I have some files in my directory. I need to amend the total number of
lines to be added in the starting
line of each file.

For example, please refer the content of the file "file.dat" below.

\h:\w #> cat file.dat
hai
hello
end
Nice day
\h:\w #>

After your command, the output should be below.

\h:\w #> cat file.dat
Total no. of lines: 4
hai
hello
end
Nice day
\h:\w #>

We can do this in sed and awk through a single command. But we will
avoid the sed and awk stuff's for some time.
and can just try using simple unix commands for now.

Regards,
Sandeep
