pattern parsing
Can somebody show me an example of of using either '#' or '?' to remove
part of string.
I am reading files from directories and I want to check if file ends with *.log *.dmp or begins with a arch_*
I DONT want to use AWK or SED to do this since there maybe 1000's of files I need to test and this will slow me down. Therefore I want to try shell pattern matching, which I believe would be much faster.
I am trying to get something like this to work:
[code]
This is my attempt to try and remove the 'xxx' from 'xxx.dmp' and only
try to get the '.dmp' part.
filename=xxx.dmp
x="${filename%.}"
Also an example of how to remove everthing AFTER "arch_" would be
appreciated too.
Ie:
filename=arch_1234_hello here I want to remove "1234_hello"
[\code]

LEARN ABOUT OPENSOLARIS
remove
remove(3C) Standard C Library Functions remove(3C)
NAME
remove - remove file
SYNOPSIS
#include <stdio.h>
int remove(const char *path);
DESCRIPTION
The remove() function causes the file or empty directory whose name is the string pointed to by path to be no longer accessible by that
name. A subsequent attempt to open that file using that name will fail, unless the file is created anew.
For files, remove() is identical to unlink(). For directories, remove() is identical to rmdir().
See rmdir(2) and unlink(2) for a detailed list of failure conditions.
RETURN VALUES
Upon successful completion, remove() returns 0. Otherwise, it returns -1 and sets errno to indicate an error.
