I have read that md5sum for 2 different files can never be same so it is accurate but time consuming.
Code:
$time cksum /data/sumeet/iso/WINXPSP3.iso
1295489342 704163840 /data/sumeet/iso/WINXPSP3.iso
real 0m7.242s
user 0m1.712s
sys 0m0.304s
$time md5sum /data/sumeet/iso/WINXPSP3.iso
0cd0c28b54a7904b36617274acc73160 /data/sumeet/iso/WINXPSP3.iso
real 0m1.676s
user 0m1.392s
sys 0m0.260s
$time cksum /data/sumeet/iso/WINXPSP3.iso
1295489342 704163840 /data/sumeet/iso/WINXPSP3.iso
real 0m1.892s
user 0m1.656s
sys 0m0.228s
I think disparity between time taken by cksum for same file may be due to caching.
Anyway , my question is which is fastest file content verification (forget byte count ) ?
