Hello all,
I have one problem. I am designing a script. Which will look for a certain pattern for file name. If pattern matches, then it will pick the file. but I am unable to give proper pattern.
So whenever, any file which will match the above pattern will be get picked.
like
Code:
SWH_PI_123434ABC.FIN
This one I have copied from one reference script. Can someone please let me know how to design the patterns? Or what is the basic thumb rules while creating such patterns. Means when to take which pattern.
I am really confused in
Code:
+\.
or
Code:
[0-9]+\.
or
Code:
[A-Za-z]
. Please help me to understand such syntaxes or patterns..
:) I want to rename a file by giving the actual date as a file name.
Is there a command for this?
For example file is this: a.txt
I want to copy it with a command like this: a20050510.txt (3 Replies)

shellexp
SHELLEXP(3) Library Functions Manual SHELLEXP(3)NAME
shellexp - match string against a cruft filter pattern
SYNOPSIS
extern int shellexp(const char *string, const char *pattern);
DESCRIPTION
The shellexp() function is similar to fnmatch(3), but works with cruft patterns instead of standard glob(7) patterns. The function returns
a true value if string matches the cruft pattern pattern, and a false value (0) otherwise. Returns -1 in case of pattern syntax error.
Cruft patterns are similar to glob(7) patterns, but are not fully compatible. The following special characters are supported:
? (a question mark)
matches exacly one character of string other than a slash.
* matches zero or more characters of string other than a slash.
/** or /**/
matches zero or more path components in string. Please note that you can only use ** when directly following a slash, and further-
more, only when either directly preceding a slash or at the very end of pattern. A ** followed by anything other than a slash makes
pattern invalid. A ** following anything else than a slash reduces it to having the same effect as *.
[character-class]
Matches any character between the brackets exactly once. Named character classes are NOT supported. If the first character of the
class is ! or ^, then the meaning is inverted (matches any character NOT listed between the brackets). If you want to specify a
literal closing bracket in the class, then specify it as the first (or second, if you want to negate) character after the opening
bracket. Also, simple ASCII-order ranges are supported using a dash character (see examples section).
Any other character matches itself.
EXAMPLES
/a/b*/*c
matches /a/b/xyz.c, as well as /a/bcd/.c, but not /a/b/c/d.c.
/a/**/*.c
matches all of the following: /a/a.c, /a/b/a.c, /a/b/c/a.c and /a/b/c/d/a.c.
/a/[0-9][^0-9]*
matches /a/1abc, but not /a/12bc.
BUGS
Uses constant-length 1000 byte buffers to hold filenames. Also uses recursive function calls, which are not very efficient. Does not vali-
date the pattern before matching, so any pattern errors (unbalanced brackets or misplaced **) are only reported when and if the matching
algorithm reaches them.
