i'm searching a file for a particular month. if the month is not found, i want the script to automatically look for the month before the month that wasn't found.
so if i searched for jun and jun isn't found, i want the script to know to search back for may. if may is also not found, i want the script to go back one more month.
You haven't told us which shell you are using, so i suppose you are using Korn shell. If not you will have to adapt the solution to your shell yourself (consider this your penance for not telling us everything we need to know ;-)) ).
You can do this by implementing a function, which accepts a months name and returns the name of the previous month.
The following function accepts the months name (as long as its first three characters match the output of the "%b" directive of date - "Jan", "Feb", etc., case-insensitively) and prints the name of the previous month in the same format (3 characters, first capitalized). It returns the number of the month found this way as integer or 255, if the parameter passed was not a months name.
For instance: "JANUA" will print "Dec" to <stdout> and return "12", "dec" will print "Nov" to <stdout> and return "11", "foo" will print nothing and return "255".
A possible program utilizing this function could look like this. It starts looking for a file "/path/to/myfile.Apr.ext", if it does not find it tries "/path/to/myfile.Mar.ext", then "/path/to/myfile.Feb.ext", etc., until it finds a file or has cycled through the whole year, upon which it prints an error message.
Hi all,
i developed a script to measure the uptime of a process in a Solaris 10/11 environments.

Hi, I was debating if I should put this in the dummies or scripts section, I apologize in advance if I chose poorly.
Fairly new to Unix and BASH scripting but I thought I made it fairly well given my limited understanding. However, the output indicates that it's looping and I'm ending up with a... (5 Replies)
Hi,
hope I am posting in the right section.
My problem is that I have 2 or more arguments passed and I want to check if the arguments passed exists or not.
The first argument should not exist and the remaining others should exist.

Hi all
Sorry for the basic question, but i am writing a shell script to get around a slightly flaky binary that ships with one of our servers. This particular utility randomly generates the correct information and could work first time or may work on the 12th or 100th attempt etc !.... (4 Replies)
Hi Im running this script, which is supposed to find the max value build some tables and then stop running once all the tables are built. Thing is , it keeps assigning a null value to $h and then $g is null so it keep building tables i.e. testupdateNUL. How can I stop this? Here is what I have:

I'm trying to understand if it's possible to create a set of variables that are numbered based on another variable (using eval) in a loop, and then call on it before the loop ends.
As an example I've written a script called question (The fist command is to show what is the contents of the... (2 Replies)
Sorry for such a dreadful title, but I'm not sure how to be more descriptive. I'm hoping some of the more gurutastic out there can take a look at a solution I came up with to a problem, and advice if there are better ways to have gone about it.
