replace nulls with whitespaces in a file
Hi,
i have a file which contains data in fixed length. each row contains data of 10 characters fixed length. The data in the file appears like 4567782882
some times i may recieve dat less than fixed length of 10. in such a case i find nulls appended at the trailing spaces when i do a hexdump. i should replace this nulls with whitespaces. how could this be done?
the possiblities where i may recieve nulls in the data is:
123 678910
12345
1
etc..
in all th above cases the nulls should be replaced by white spaces

I just had a filesystem / file corruption issue on my HSP's server due to disk capacity limits and fileswapping. I discovered that certain files got corrupted when fileswapping was not successful and they ended up with a string of control characters, or what I believe to be nulls, in them.

mlmmj-recieve
mlmmj-recieve(1) General Commands Manual mlmmj-recieve(1)
NAME
mlmmj-recieve - recieve mails for an mlmmj managed mailinglist
SYNOPSIS
mlmmj-recieve -L /path/to/listdir [-h] [-V] [-P] [-F]
-h: This help
-F: Don't fork in the background (debugging only)
-L: Full path to list directory
-P: Don't execute mlmmj-process (debugging only)
-V: Print version
DESCRIPTION
The mlmmj-recieve binary is the one specified in the mailserver configuration file (aliases file), which writes the mail to the <list-
dir>/incoming directory and invokes mlmmj-process unless the -P option is specified. On systems using mailservers supporting the
/etc/aliases file, a line to activate an mlmmj managed mailinglist would look like this:
list: "|/usr/bin/mlmmj-recieve -L /var/spool/mlmmj/list/"
It's very important to specify the full path to the binary, or the mailinglist will not function.
When the -F option is used, it will not fork in the background. The reason it forks is that if delivery of a mail takes longer time than
the mail server will allow a command to be idle before presumed dead, the mail server would kill it.
