How to delete several lines from file by line number?
Hi
I am using the following command to delete a line from the file by line number:
Code:
line_number=14
sed "${line_number}d"  inputfilename > newfilename

Is there a way to modify this command to specify the range of lines to be deleted, lets say from line 14 till line 5 ?

I tried using the while loop but execution takes too long.
Thanks a lot

See if this works for you:
Code:
line_From=14
line_To=17
sed "${line_From},${line_To}d"  inputfilename > newfilename
