An alternative solution, this time using just the shell, without the help of external programs (except by the cp program, of course):

PHP Code:


for file in *5001*; do cp $file ${file/01/06};done

the key here is the ${//} shell's parameter expansion operator:

extracted from GNU Bash man page:

Quote:

${parameter/pattern/string}
${parameter//pattern/string}
The pattern is expanded to produce a pattern just as in pathname expansion. Parameter is expanded and the longest match of pattern against its value is
replaced with string. In the first form, only the first match is replaced. The second form causes all matches of pattern to be replaced with string.
If pattern begins with #, it must match at the beginning of the expanded value of parameter. If pattern begins with %, it must match at the end of the
expanded value of parameter. If string is null, matches of pattern are deleted and the / following pattern may be omitted. If parameter is @ or *, the
substitution operation is applied to each positional parameter in turn, and the expansion is the resultant list. If parameter is an array variable sub-
scripted with @ or *, the substitution operation is applied to each member of the array in turn, and the expansion is the resultant list.

this operator is available on the Korn Shell to.

mb_ereg_replace - Replace regular expression with multibyte support

SYNOPSIS

       string mb_ereg_replace (string  $pattern, string  $replacement, string  $string, [string  $option = "msr"])

DESCRIPTION

	Scans $string for matches to $pattern, then replaces the matched text with $replacement

PARAMETERS

	      o $pattern
		- The regular expression pattern.  Multibyte characters may be used in $pattern.

	      o $replacement
		- The replacement text.

	      o $string
		- The string being checked.

	      o $option
		-  Matching  condition	can  be  set by $option parameter. If i is specified for this parameter, the case will be ignored. If x is
		specified, white space will be ignored. If m is specified, match will be executed  in  multiline  mode	and  line  break  will	be
		included  in '.'. If p is specified, match will be executed in POSIX mode, line break will be considered as normal character. If e
		is specified, $replacement string will be evaluated as PHP expression.

RETURN VALUES

	The resultant string on success, or FALSE on error.

NOTES

       Note

	      The internal encoding or the character encoding specified by mb_regex_encoding(3) will be used as the character  encoding  for  this
	      function.

       Warning

	      Never  use  the  e  modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace(3)). Not
	      taking care of this will most likely create remote code execution vulnerabilities in your application.
