It would be nice if unix supported circular files. On old HP3000, I could build a file of desired size, specify cir attribute, and output to the file would be circular.
The following downsizes log.txt back to 800 lines after it hits 1200 lines, but you could use "wc -c" to control on number of characters instead. I use tail +nnn logic because tail -nnn will go back only so far.

Does anyone know a way to determine the maximum filesize on a file system on Solaris, HP-UX, AIX, Linux, and OSF1 using the command line?

Hi All,
We are running HP rp7400 box with hpux 11iv1.
Recently, we changed 3 kernel parameters
a) msgseg from 32560 to 32767
b) msgmnb from 65536 to 65535
c) msgssz from 128 to 256
Then we noticed that all application debug file size increase upto 2GB then it stops. So far we did not... (1 Reply)
I'm trying to set the open files value to 4000 on a SLES 9 system.
Current values:ulimit -n
1024
I can set it using this:ulimit -n 4000
ulimit -n
4000
But this obviously sets it only for the shell session where I run the command to set it. I want to set this to 4000 for all time.

There is a file in my Unix Server whose size will be constant.
But every day when the sheduled jobs run in the server, that file gets updated but the size does not change.

It is dispalyed as a binary file.
Can anyone please explain how that file is created.

Hello All,
I am working on an issue, where I need to check the max file size of a file. If the file size exceeds 2 GB, then I need to generate an error message. Since the file system does not allow a file to be created larger than 2 GB, I am planning to use named pipes & AWK file to acheive my... (6 Replies)
I have a system with the following settings:
min:0.10
Assigned: 2.0
Max: 6.0
Partition is uncapped weight is 128.

The actual pool has 16.
I remember reading about this somewhere but I don't remember can anyone... (3 Replies)
Hi,
I've compiled a 64-bit version of ClamAV 0.98.7 on my Solaris 10 SPARC server. I have a selection of files all containing the eicar signature but clamd is only picking up the signature in the files <2GB.
I have the following set in clamd.conf, to remove file size checking:

tail
TAIL(1) FSF TAIL(1)NAME
tail - output the last part of files
SYNOPSIS
tail [OPTION]... [FILE]...
DESCRIPTION
Print the last 10 lines of each FILE to standard output. With more than one FILE, precede each with a header giving the file name. With
no FILE, or when FILE is -, read standard input.
Mandatory arguments to long options are mandatory for short options too.
--retry
keep trying to open a file even if it is inaccessible when tail starts or if it becomes inaccessible later -- useful only with -f
-c, --bytes=N
output the last N bytes
-f, --follow[={name|descriptor}]
output appended data as the file grows; -f, --follow, and --follow=descriptor are equivalent
-F same as --follow=name --retry
-n, --lines=N
output the last N lines, instead of the last 10
--max-unchanged-stats=N
with --follow=name, reopen a FILE which has not changed size after N (default 5) iterations to see if it has been unlinked or
renamed (this is the usual case of rotated log files)
--pid=PID
with -f, terminate after process ID, PID dies
-q, --quiet, --silent
never output headers giving file names
-s, --sleep-interval=S
with -f, sleep for approximately S seconds (default 1.0) between iterations.
-v, --verbose
always output headers giving file names
--help display this help and exit
--version
output version information and exit
If the first character of N (the number of bytes or lines) is a `+', print beginning with the Nth item from the start of each file, other-
wise, print the last N items in the file. N may have a multiplier suffix: b for 512, k for 1024, m for 1048576 (1 Meg).
With --follow (-f), tail defaults to following the file descriptor, which means that even if a tail'ed file is renamed, tail will continue
to track its end. This default behavior is not desirable when you really want to track the actual name of the file, not the file descrip-
tor (e.g., log rotation). Use --follow=name in that case. That causes tail to track the named file by reopening it periodically to see if
it has been removed and recreated by some other program.
