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.

memory_cb
MEMORY_CS(4) Kernel Interfaces Manual MEMORY_CS(4)
NAME
memory_cb - CardBus memory driver
SYNOPSIS
insmod memory_cb.o [pc_debug=n]
DESCRIPTION
Memory_cb gives direct memory access to the address spaces of CardBus cards. It provides character-mode devices for accessing a card's PCI
configuration space, up to six mapped memory or IO regions, and its expansion ROM space. When loaded, memory_cb will allocate a free major
device number. For each card, it will report which address spaces are available, and their sizes. Minor numbers have the form 'dddddsss',
where 'ddddd' is the instance number and 'sss' is the memory space for that instance. When memory_cb is bound to a card, it will report
its major and minor device numbers to cardmgr(8).
The default memory card initialization script creates device special files for all eight card address spaces, though for a particular card,
some of these may be unavailable. These devices have the following names:
/dev/cbmem#s0
The card's PCI configuration space.
/dev/cbmem#s[1-6]
The IO or memory spaces mapped by the card's six Base Address Registers.
/dev/cbmem#s7
The card's expansion ROM space.
The character special devices can be used to read and write arbitrary numbers of bytes to arbitrary locations. The memory_cb driver can be
bound to any card regardless of function.
PARAMETERS
pc_debug=n
Selects the PCMCIA debugging level. This parameter is only available if the module is compiled with debugging enabled. A non-zero
value enables debugging.
