How do I pass a wild card as a variable
Hi,
I would like to pass a wild card as part of an argument. But when I do it the script views the wild card as text.
Example:
sFile=MG1A*
sort $sFile > $sFile.sorted
What I get is MG1A*.sorted
The problem is I am passed a series of files where the first few characters like "MG1A" are constant. The additional part of the file name is a date time stamp. I will never know the exact date time stamp. I need to do a search for MG1A* which will find me one file. How can I write my script so the variable $sFile will know that the "*" in MG1A* is a wild card not text?
I know I can write code to run "ls" on a directory and get all file names then write a loop or do statement to do my sort based upon that list regardless of the file name. But I have more files in the dir than I want to grab. I also know I can run the "ls" command output the file names in the dir to a file and grep for the part fo the file names I am looking for. I also think this can be done if I pput the whole comamnd iBut current design restricts me form going that path. It would require a whole re-write and I am trying to avoid that.
Thank you.

NAME
bwild - Bacula's 'wildcard' engine
SYNOPSIS
bwild [options] -f <data-file>
DESCRIPTION
This manual page documents briefly the bwild command.
This is a simple program that will allow you to test wild-card expressions against a file of data.
OPTIONS
A summary of options is included below.
-? Show version and usage of program.
-d nn Set debug level to nn.
-dt Print timestamp in debug output
-f <data-file>
The data-file is a filename that contains lines of data to be matched (or not) against one or more patterns. When the program is
run, it will prompt you for a wild-card pattern, then apply it one line at a time against the data in the file. Each line that
matches will be printed preceded by its line number. You will then be prompted again for another pattern.
Enter an empty line for a pattern to terminate the program. You can print only lines that do not match by using the -n option, and
you can suppress printing of line numbers with the -l option.
-n Print lines that do not match
-l Suppress lines numbers.
-i use case insensitive match.
