Subject: [PATCH] badblocks : Print progress in percent complete and time elapsed in verbose mode.
Hi Ted,
I am trying to address debian bug# 429739 to print the progress of
badblocks in percent and time elapsed. I have added a new option '-V'
which instead of showing progress in blocks gives output as below.
/home/mkatiyar/e2fs-git/e2fsprogs_work/sbin> ./badblocks -V myfs
Checking blocks 0 to 2353935
Checking for bad blocks (read-only test): 16.68% done, 14s elapsed
/home/mkatiyar/e2fs-git/e2fsprogs_work/sbin> ./badblocks -V myfs
Checking blocks 0 to 2353935
Checking for bad blocks (read-only test): 86.79% done, 01m:04s elapsed
Appreciate your comments on the below patch.
Make badblocks -v print percent complete and time elapsed. Addresses
debian bug# 429739.
