Could you please be more clear on your requirement, as I understood you are requesting for checking a file's existance. Let me give you an example for same.
In my case file is present so it will give following output. Also please refer man test for more information. Hope this helps.
Thanks,
R. Singh
file will exist all the time and it will get update with data(like log file).
like push_back in cpp, data will be pushed into the file after every iteration.
I want to read Time value.
But trick is I want to read last two time occurrences and compare file existence.
If you see in my previous reply, last two time values are 2 and 3.
I want to check whether data files(these files are different) for
these time are present or not.
In the same case, since simulation is still going there will be no data files for time 3. After finished with 2nd simulation data some data will be written. but in log file I can see Time =3 as well which is not done yet.
Let me know if you still didn't understand.
Thanks for help.

Did not use 'wait' yet.
How I understand by now the wait works only for child processes, started background.
Is there any other way to watch completion of any, not related process (at least, a process, owned by the same user?)

A regular count (SELECT value, COUNT(*) FROM data GROUP BY value) would yield:
X 3
Y 2
However, Y happens to count double so the answer should... (2 Replies)

lzcmp
XZDIFF(1) XZ Utils XZDIFF(1)NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
SYNOPSIS
xzcmp [cmp_options] file1 [file2]
xzdiff [diff_options] file1 [file2]
lzcmp [cmp_options] file1 [file2]
lzdiff [diff_options] file1 [file2]
DESCRIPTION
xzcmp and xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed
directly to cmp or diff. If only one file is specified, then the files compared are file1 (which must have a suffix of a supported com-
pression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncom-
pressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp or diff is preserved.
The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.
SEE ALSO cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
