Counting no. of lines and printing it at the start of the file
Dear users,
I need to count the number of lines in a simple text file and print the number on the first line of that same file.
I know I can count the lines using
wc -l file.txt
this gives for example
100 file.txt
I need the number 100 to be printed at the very top of file.txt i.e above the existing text (I dont want the file.txt printed).
Any help much appreciated,
