Shell Programming and Scripting

Thanks Don for this useful post

1) The data i have provided is just a dummy data because i am not allowed to provide real data.i agree with your concerns

2) I just want set of files per month/year to iterate through.

3) i want to find files with first two dates & last date for that month/year

Hi Don
I am getting below error.Any help

Code:

./tunning.sh
./tunning.sh[6]: typeset: bad option(s)

my unix version

Code:

SunOS abc100 5.8 Generic_117350-61 sun4u sparc SUNW,Sun-Fire-V440

Dummy data is fine. You can change the files' owners to "user" (or if there are multiple users, "user1", "user2", ...) and the files' group names to "group" (or "group1", "group2", ...) and the files' names to "x1.txt", "x2.txt", ... "xn.txt", but changing output like:

Code:

-rw-r--r--   1 dwc  staff    8095 Apr 22 22:11 d.txt

to:

Code:

-rw-r--r--   1 dwc  staff    8095 Apr 22  2014 d.txt

hides information that is crucial to getting the results you want. You should easily be able to the save output from ls -lt in a file, edit the file to sanitize private data, and post the sanitized output without hiding data that your script is going to need to use to get the job done.

I explicitly said "the following Korn shell script (when using a 1993 or later version of ksh)". /bin/ksh on Solaris 8 is a 1988 version of the Korn shell. The 1988 version of the Korn shell doesn't have associative arrays. The awk script I provided should work fine for you if you change awk to /usr/xpg4/bin/awk or nawk. (I don't remember the path, but there might also be a 1993 version of ksh on Solaris 8 with a pathname something like /usr/dtbin/dtksh. You might be able to find it with:
ls /usr/*/dtksh /usr/*/*/dtksh

With the output that script provides you can easily grep for ":Oct 2013:" (or any other month and year you want) to find the files for that month and year. I assume you can pick the 1st two and the last one out of the matching grep output to get the files you want to process for that month. Of course it would also be pretty easy to just modify the awk script or a shell script to pass in the month and year you want and have it only print the names of the three (or all, if there are less than three) files that you want for that month.

Try to build on what we've given you here to get what you want. If it doesn't work, start another thread showing us what you have done, what (sanitized) input you're processing, and what output you;re hoping to get.
