Trying to figure out a log dump command
Ok so i'm relatively new at UNIX and I'm trying to figure out how to make a log dump command.

My situation is a bit odd in that I'm always looking at customers boxes and as such I can't really do much to them. So everything I do in UNIX pretty much has to be a command I can type in by hand. I can't really install any apps to do things for me or anything like that since that required modifying the customers box. So I'm limited to software on the box now. We are freebsd with Bash.

So what I'm trying to do is make a command that will pull data for a specific date and time out of a bunch of different log files in different places. Then take all that information and dump it into a single log file that I can then save and look at. Which will be a big time saver for me. So that instead of having to manually dig my way through 10 log files I can just run one command and get all the data I need made into 1 file. Then I can dig through that.

I'm sure I could just do a great big long string of.. cat /folder/file | grep 'date' >> output file.

But that would require going through the entire command each time and adjust the date and time information which is going to change constantly. So I was hoping I could find a way to use variable somehow. So that I can write the command to look at variables to determine the date and time. This way all I have to do is adjust the variables to the date and time I want and the command will work. I suspect AWK can do this but really I'm just trying to figure out what kind of ideas and options I have for doing something like this.

I would appreciate any approaches to how I could accomplish this task.

Ok so I can grep for variables which is good. And I've found how I can set the variables.
Code:
#testvariable='May'; testvariable2='june'

This will allow me to easily set any number of variables. Then I can simply grep the specific log files for date and time... Now the only snag i'm running into is I can't get multiple spaces into the date. In my logs the date is.

Apr 1

with 2 spaces not 1 and anytime I set the variable it always has 1 space. Any idea how I can get 2 spaces to work?
