Exclude incomplete files in ls -rlt
Hi All,
I am bit puzzled with this requirement where I need to list the files in a directory. However, files are being continuously written to this folder through FTP. Hence I need to exclude the file which is being written at the time of listing the directory. I thought of using file time stamp. I can list files with timestamps 5 minutes before the time I run ls -lrt command. I believe time taken to ftp the file will not take more than 5 minutes based on my observation.
I am not sure how do I list file based on time. Any help on this is highly appreciated. If there is any other option, please let me know.
Thanks
Angshuman

acctcms(1M) acctcms(1M)
NAME
acctcms - command summary from per-process accounting records
SYNOPSIS
[options] files
DESCRIPTION
reads one or more files, normally in the form described in acct(4). It adds all records for processes that executed identically-named com-
mands, sorts them, and writes them to the standard output, normally using an internal summary format.
Options
recognizes the following options:
Print output in
ASCII rather than in the internal summary format. The output includes command name, number of times executed, total kcore-
minutes, total CPU minutes, total real minutes, mean size (in K), mean CPU minutes per invocation, ``hog factor'', charac-
ters transferred, and blocks read and written, as in acctcom(1M). Output is normally sorted by total kcore-minutes.
Sort by total
CPU time, rather than total kcore-minutes.
Combine all commands invoked only once under
Sort by number of command invocations.
Any file names encountered hereafter are already in internal summary format.
Process all records as total accounting records.
The default internal summary format splits each field into prime- and non-prime-time parts. This option combines the prime
and non-prime time parts into a single field that is the total of both, and provides upward compatibility with old (i.e.,
UNIX System V) style internal summary format records.
The following options can be used only with the option.
Output a prime-time-only command summary.
Output a non-prime- (offshift) time only command summary.
When and are used together, a combination prime and non-prime time report is produced. All the output summaries are total usage except
number of times executed, CPU minutes, and real minutes which are split into prime and non-prime.
EXAMPLES
A typical sequence for performing daily command accounting and for maintaining a running total is:
WARNINGS
Unpredictable output results if is used on new-style internal-summary-format files, or if it is not used with old style internal summary
format files.
