Initial Comment:
>From John Lehr:
Good Morning Group,
 
I have a question about blkls, particularly the –a option.  I am creating keyword search files with blkls and srch_strings, and I wanted to distinguish between allocated and unallocated, created one two text files for each type of block (ascii and unicode).
 
For unallocated, I used something like:
# blkls partition.dd | srch_strings –t d > text.file
 
This produced a text file of ascii strings with byte offset from unallocated blocks as desired.
 
For allocated, I tried:
# blkls –a partition.dd | srch_strings –t d > text.file
 
But, surprisingly, it looks like all blocks were exported from the partition, not just allocated blocks. (I piped blkls through ‘pv’ to meter the output and instead of getting the 83gb of allocated space, I got the whole 221gb partition).
