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.
try changing (ksh)
sFile='MG1A*'
sort $sFile > $sFile.sorted

Be sure and use single quotes - it will not expand out the wildcard at the assignment line.
