however when I tried to see the result of output.txt
#cat output.txt

Hi,
I have to update last line of a text file with the number of lines in that file. This last line will have text such as 0.0000 and I should replace this with number lines. If lines are 20 then it should be replaced with 00020. Any sed or awk cmd help would be appreciated (3 Replies)
