wc -L giving incorrect length of longest line
Running below line gives 3957 as length of longest line in file 20121119_SRMNotes_init.dat

Code:
awk ' { if ( length > 3950 ) { x = length } }END{ print x }' 20121119_SRMNotes_init.dat

While wc -L 20121119_SRMNotes_init.dat gives output as 4329. Why is there a difference between these two commands.

Thanks
