The below shell script obtains a command and an alias from the user then appends the alias to the users ~/.aliases file. It is useful with cd commands and saves typing; instead of going cd /foo/bar/bonk/boo/what/whatelse/dir I create an alias something like "godir".
It's not done and I will... (2 Replies)

rewinddir
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.
