The file is not truly deleted until all references to it are closed. Until then, it is kept on disk, generally inaccessible to anything except the programs that still have it open.
You should truncate logfiles instead of deleting them to clear space:

Hi,
First of all I appreciate this group very much for its informative discussions and posts.
Here is my question.
I have one process whose virtual memory size increases linearly from 6MB to 12MB in 20 minutes. Does that mean my process has memory leaks?
In what cases does the... (4 Replies)

Hi,
Would any one be so kind to explain me :

Specialy what is the impact of :

virtual memory
on performance of applications for a user.
Many thanks.
PS :
this is what I can see in MAN :

OPTIONS -h, --help
display this help and exit
-V, --version
output version information and exit
-a, --change-types=<ot>,<nt>
change the block types of a logfile
-b, --block-size=<bytes>
block size in bytes [default 512]
-c, --create-logfile[=<tt>]
create logfile from list of blocks [+-]
-d, --delete-if-done
delete the logfile if rescue is finished
-D, --done-status
return 0 if rescue is finished
-f, --force
overwrite existing output files
-i, --input-position=<bytes>
starting position of rescue domain [0]
-l, --list-blocks=<types>
print block numbers of given types (?*/-+)
-m, --domain-logfile=<file>
restrict domain to finished blocks in file
-n, --invert-logfile
invert block types (finished <-> others)
-o, --output-position=<bytes>
starting position in output file [ipos]
-p, --compare-logfile=<file>
compare block types in domain of both files
-q, --quiet
suppress all messages
-s, --max-size=<bytes>
maximum size of rescue domain to be processed
-t, --show-status
show a summary of logfile contents
-v, --verbose
be verbose (a 2nd -v gives more)
-x, --xor-logfile=<file>
XOR the finished blocks in file with logfile
-y, --and-logfile=<file>
AND the finished blocks in file with logfile
-z, --or-logfile=<file>
OR the finished blocks in file with logfile
Numbers may be followed by a multiplier: b = blocks, k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi =
