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.

I'm relatively new to Pro*C programming. In the following example:
char name; EXEC SQL SELECT 'John Doe' INTO :name FROM DUAL;
"John Doe" is in positions 0-7, blanks in 8-19, and a null in 20. I would really prefer the null to be in position 8 and I don't care what's after that. I wrote a... (1 Reply)
Hi,
I am trying to replace nulls with spaces in every record of a '|' delimited file. I used this command -
cat input.dat | sed 's/||/| |/g' > output
But if a space appears twice '| | |' , then only the first null is getting replaced with a space. The second one remains as a null. I... (7 Replies)

When I try to sort a file where some records contain nulls i.e. hex 00 the sort truncates the record when it reaches the null and writes message:
"sort: warning: missing NEWLINE added at end of input file myfile"
I'm assuming from this that the sort sees the null as a special character and... (6 Replies)

I am trying to count the number of columns in a delimited flat file. The record is tab delimited. When I use the command wc -w, I am getting unexpected results when the record contains a NULL value. I believe it is because there is a "word" missing.
The below example will return 4 words... (2 Replies)
Ok,
I'm stuck here with a plan to get what I need done completed.
I want to use perl to produce a document. lets say the document will be a pdf document.
Now, is there a way for me to put a tiny little code in that pdf document that can make the pdf file null itself if run on a non-unix... (2 Replies)
I want to remove from a file the trailing null characters (0x00) and stop doing so when a different byte is found (which should not be deleted), and either put the result to the same file or a different one.
Any ideas? (9 Replies)

ttys - terminal control database file for trusted systems
SYNOPSIS DESCRIPTION
The system supports a single terminal control database containing entries for each local terminal that can log into the system. Authentica-
tion programs use information contained in the terminal control database to determine if login from the terminal is permitted. Additional
fields are maintained for informational purposes.
The format of the terminal control database file is identical to other system authentication database files. For more information on the
file format, see authcap(4). The file consists of keyword field identifiers and values for those fields. The keyword identifiers supported
and their use include:
This field defines the terminal device name for the entry. The terminal device
is expected to be contained in the directory, therefore this prefix should not be specified. If the terminal entry
describes the device, the field should contain
This field records the user id of the last user to successfully login using
the terminal device.
This field records the last successful login time to the terminal device.
This field records the last unsuccessful login time to the terminal device.
This field records the number of consecutive unsuccessful login attempts to
the terminal device.
This field specifies the maximum number of consecutive unsuccessful login
attempts permitted using the terminal before the terminal is locked. Once the terminal is locked, it must be unlocked by
an authorized administrator.
This field specifies the login timeout value (sec).
This field specifies the delay between login tries (sec).
This flag field indicates whether the terminal device has been administratively
locked or not. This field is manipulated by authorized administrators only.
EXAMPLES
The following is an example of a terminal control database entry:
This entry is for the system console device, The most recent successful login session was for the user The entry records the system time
for the current successful login and the time of the most recent unsuccessful login attempt.
WARNINGS
Remote terminals (ptys) should not be added to the or databases. Device name formats treated as ptys by login are:
where x is a letter, and y is a hex number
where x is a letter, and y is a hex number
HP-UX 11i Version 3 is the last release to support
trusted systems functionality.
