Assuming that the flavour of UNIX you are using has a stat command, then something like this could be used to create your filename:
The stat command generates the epoch timestamp for the named file and the awk script is used to format it into something useful. The %y format supported by stat isn't very filename friendly.
If you are using FreeBSD, then the stat command format is a wee bit different. On the 6.2 BSD system I have it's: stat -f %a file-name
There is a caution in the man page for stat on Linux that states that a shell may implement an internal stat command that will override the binary in /bin

Hello,
I've created the script below to compare the content of two files with a delay of an hour. After an hour, the lines that exist in both files, will be printed and executed.
The script now uses a counter to countdown 50 minutes. But what I would prefer is to check the file timestamp of... (3 Replies)

I need to be able to identify files with file timestamps greater than a given timestamp.
I am using the following solution, although it appears to compare files at the "seconds" granularity and I need it at the milliseconds. When I tested my solution, it missed files that had timestamps... (3 Replies)
Hi Friends,
I have the following logfile. Currently time in india is 07/31/2014 12:33:34 and i have the following content in logfile. I want to display only those entries which contain string 'Exception' within last 3 hours. In this case, it would be the last line only

perf_3.2-stat
PERF_3.2-STAT(1) perf Manual PERF_3.2-STAT(1)NAME
perf-stat - Run a command and gather performance counter statistics
SYNOPSIS
perf stat [-e <EVENT> | --event=EVENT] [-a] <command>
perf stat [-e <EVENT> | --event=EVENT] [-a] -- <command> [<options>]
DESCRIPTION
This command runs a command and gathers performance counter statistics from it.
OPTIONS
<command>...
Any command you can specify in a shell.
-e, --event=
Select the PMU event. Selection can be a symbolic event name (use perf list to list all events) or a raw PMU event (eventsel+umask) in
the form of rNNN where NNN is a hexadecimal event descriptor.
-i, --no-inherit
child tasks do not inherit counters
-p, --pid=<pid>
stat events on existing process id
-t, --tid=<tid>
stat events on existing thread id
-a, --all-cpus
system-wide collection from all CPUs
-c, --scale
scale/normalize counter values
-r, --repeat=<n>
repeat command and print average + stddev (max: 100)
-B, --big-num
print large numbers with thousands' separators according to locale
-C, --cpu=
Count only on the list of CPUs provided. Multiple CPUs can be provided as a comma-separated list with no space: 0,1. Ranges of CPUs are
specified with -: 0-2. In per-thread mode, this option is ignored. The -a option is still necessary to activate system-wide monitoring.
Default is to count on all CPUs.
-A, --no-aggr
Do not aggregate counts across all monitored CPUs in system-wide mode (-a). This option is only valid in system-wide mode.
-n, --null
null run - don't start any counters
-v, --verbose
be more verbose (show counter open errors, etc)
-x SEP, --field-separator SEP
print counts using a CSV-style output to make it easy to import directly into spreadsheets. Columns are separated by the string
specified in SEP.
-G name, --cgroup name
monitor only in the container (cgroup) called "name". This option is available only in per-cpu mode. The cgroup filesystem must be
mounted. All threads belonging to container "name" are monitored when they run on the monitored CPUs. Multiple cgroups can be provided.
Each cgroup is applied to the corresponding event, i.e., first cgroup to first event, second cgroup to second event and so on. It is
possible to provide an empty cgroup (monitor all the time) using, e.g., -G foo,,bar. Cgroups must have corresponding events, i.e., they
always refer to events defined earlier on the command line.
-o file, --output file
Print the output into the designated file.
--append
Append to the output file designated with the -o option. Ignored if -o is not specified.
--log-fd
Log output to fd, instead of stderr. Complementary to --output, and mutually exclusive with it. --append may be used here. Examples:
3>results perf stat --log-fd 3 -- $cmd 3>>results perf stat --log-fd 3 --append -- $cmd
EXAMPLES
$ perf stat -- make -j
