If condition to check one file newer than the other - first file name uncertain
Dear All,
I'm new to unix scripting. I'm trying to write an utility script which has to check if one file is newer than another one. The condition is I dont know the full name of the first file. I searched google and this forum for any such examples, but couldn't find any or may be I would have missed it.
I wrote this simple check using if, but it is not working.
If i give a definite file name, it prints "file found", but when I use an *, even if the file is present it says "file not found"
I will have to use the wildcard charcater * bcoz each time the text following "xyz" is different.
Could anyone please tell me how to fix this.
Your help is much appreciated.
Thanks

I am writing a script file which sends the log files along with their size in a folder named log to a file called temp.log using the following cmd:
ls -st 190_GSTV_HUX_003QISCGSK026** >> /home/user/temp.log
the temp.log looks like this:

I know how to check if any file has a unix process using a file by looking at 'lsof <fullpath/filename>' command.
I think using lsof is very expensive. Also to make it accurate we need to inlcude fullpath of the file.

This should be a simple script, but can't find one with google search.

idl2wrs
IDL2WRS(1) The Wireshark Network Analyzer IDL2WRS(1)NAME
idl2wrs - CORBA IDL to Wireshark Plugin Generator
SYNOPSIS
idl2wrs filename
DESCRIPTION
idl2wrs is a program that takes a user specified CORBA IDL file and generates "C" source code for a Wireshark "plugin".
This resulting file can be compiled as a Wireshark plugin, and used to monitor GIOP/IIOP traffic that is using this IDL.
idl2wrs is actually a shell script wrapper for two Python programs.
These programs are:
wireshark_be.py - Contains the main IDL Visitor Class
wireshark_gen.py - Contains the Source Code Generator Class
idl2wrs supports heuristic dissection of GIOP/IIOP traffic, and some experimental code for explicit dissection, based on Object Key <->
Repository Id mapping. However, code for heuristic based plugins is generated by default, and users should consider this the preferred
method unless you have some namespace collisions.
OPTIONS
Currently there are no options. idl2wrs can be invoked as follows.
1. To write the C code to stdout.
idl2wrs <your_file.idl>
eg: idl2wrs echo.idl
2. To write to a file, just redirect the output.
idl2wrs echo.idl > packet-test.c
ENVIRONMENT
idl2wrs will look for wireshark_be.py and wireshark_gen.py in $PYTHONPATH/site-packages/ and if not found, will try the current directory
./
The -p option passed to omniidl (inside idl2wrs) indicates where wireshark_be.py and wireshark_gen.py will be searched. This may need
tweaking if you place these files somewhere else.
If it complains about being unable to find some modules (eg tempfile.py), you may want to check if PYTHONPATH is set correctly.
eg: PYTHONPATH=/usr/lib/python1.5/
SEE ALSO wireshark(1), tshark(1)NOTES
idl2wrs (including wireshark_be.py and wireshark_gen.py) are part of the Wireshark distribution. The latest version of Wireshark can be
found at <http://www.wireshark.org>.
idl2wrs uses omniidl, an IDL parser, and can be found at <http://omniorb.sourceforge.net/>
TODO
Some of the more important things to do are:
o Improve Explicit dissection code.
o Improve command line options.
o Improve decode algorithm when we have operation name collision.
