Top Forums Shell Programming and Scripting Print the name of files in the directory using Perl Post 302606910 by Skrynesaver on Tuesday 13th of March 2012 05:59:23 AM

If you are running a Perl script there is no need to spawn a shell to do this, Perl has a number of ways (as always) of doing this, you can use a glob to get the values
Code:
print join("\n",glob("$dir_name/*")),"\n";

Or you could open the directory and read the contents.
Code:
opendir(my $directory,"$dir_name"); 
print join("\n", grep {! /^\./} sort(readdir $directory));
closedir($directory);

The glob is obviously easier to use, however if you need to do more complex processing than just printing the filenames the opendir, readdir , closedir approach gives you more flexibility.

rewinddir(3C)						   Standard C Library Functions 					     rewinddir(3C)

NAME
rewinddir - reset position of directory stream to the beginning of a directory SYNOPSIS
#include <sys/types.h> #include <dirent.h> void rewinddir(DIR *dirp); DESCRIPTION
The rewinddir() function resets the position of the directory stream to which dirp refers to the beginning of the directory. It also causes the directory stream to refer to the current state of the corresponding directory, as a call to opendir(3C) would have done. If dirp does not refer to a directory stream, the effect is undefined. After a call to the fork(2) function, either the parent or child (but not both) may continue processing the directory stream using read- dir(3C), rewinddir() or seekdir(3C). If both the parent and child processes use these functions, the result is undefined. RETURN VALUES
The rewinddir() function does not return a value. ERRORS
No errors are defined. USAGE
The rewinddir() function should be used in conjunction with opendir(), readdir(), and closedir(3C) to examine the contents of the direc- tory. This method is recommended for portability. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ |MT-Level |Safe | +-----------------------------+-----------------------------+ SEE ALSO
