To count the number of files in the current directory, you can use "ls" (<http://pubs.opengroup.org/onlinepubs/9699919799/utilities/ls.html>) and "wc" (<http://pubs.opengroup.org/onlinepubs/9699919799/utilities/wc.html>) as follows:
Code:
ls -1 | wc -l

Then use "[" a.k.a. "test" (<http://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html>) to see if the result is greater than or equal to 10.
Code:
if [ "`ls -1 | wc -l`" -ge 10 ]; then
    # Do something.
fi

And you can get the name of the oldest file using "ls" and "tail" (<http://pubs.opengroup.org/onlinepubs/9699919799/utilities/tail.html>) as follows:
Code:
ls -t | tail -n 1

To get the date, use "date" (<http://pubs.opengroup.org/onlinepubs/9699919799/utilities/date.html>). Something like this should be what you want:
Code:
date '+%m%d%Y'

And you can add the date to a file whose name ends in ".txt" using "sed" (<http://pubs.opengroup.org/onlinepubs/9699919799/utilities/sed.html>). For example:
Code:
echo 'abc.txt' | sed "s/[.]txt\$/${the_date}.txt/"

I'm not sure exactly what you're trying to do, but hopefully this will help get you started.

binary versioning

Dear Members, Do you know any information about versioning a binary file. That means test.out 1.0.0, 1.0.1, 1.1.0, and so on. Can I manually edit version number (both major and minor) and revision number myself (how?) or any utility to set version number (which one?). Best Regards, Francesco (2 Replies)

verifier

verifier(1M)						    Application Server Utility						      verifier(1M)

NAME

       verifier - validates the J2EE Deployment Descriptors against application server DTDs

SYNOPSIS

       verifier [-v] [-d destination_directory] [-r [a|w|f]] jar_filename

       Use the verifier utility to validate the J2EE deployment descriptors and the Sun ONE Application Server specific deployment descriptors. If
       the application is not J2EE compliant, an error message is printed.

       When you run the verifier utility, two results files are created in XML and TXT format. The location where the files  are  created  can	be
       configured  using  the  -d  option.  The directory specified as the destination directory for result files should exist. If no directory is
       specified, the result files are created in the current directory. Result files are named as jar_filename_verified.xml and jar_filename_ver-
       ified.txt

       The  XML  file  has  various sections that are dynamically generated depending on what kind of application or module is being verified. The
       root tag is static-verification which may contain the tags application, ejb, web, appclient, connector, other, error and failure-count. The
       tags are self explanatory and are present depending on the type of module being verified. For example, an EAR file containing a web and EJB
       module will contain the tags application, ejb, web, other, and failure-count.

       If the verifier ran successfully, a result code of 0 is returned. A non-zero error code is returned if the verifier failed to run.

OPTIONS

       -v			verbose debugging is turned on.

       -d		       identifies where the result files get placed.

       -r		       identifies the reporting level defined as one of the following:

				 o  a sets output reporting level to display all results (default)

				 o  w sets output reporting level to display warning and failure results

				 o  f sets output reporting level to display only failure results

       jar_filename	       name of the ear/war/jar file to perform static verification on. The results of verification are placed in two files
			       jar_filename_verified.xml and jar_filename_verified.txt in the destination directory.

       Example 1: Using verifier in the Verbose Mode

       example% verifier -v -d /verifier-results -rf sample.ear

       Where  -v  runs	the  verifier in verbose mode, -d specifies the destination directory, and -rf displays only the failures. The results are
       stored in /verifier-results/sample.ear_verified.xml and /verifier-results/sample.ear_verified.txt.
