If I have a string defined as:
MyString=abcde
echo $MyString
How can I loop through it character by character? I haven't been able to find a way to index the string so that I loop through it.

strncpy
strncpy(9r)strncpy(9r)NAME
strncpy - General: Copies a null-terminated character string with a specified limit
SYNOPSIS
char * strncpy(
char *s1,
char *s2,
int n );
ARGUMENTS
Specifies a pointer to a buffer of at least n bytes. Specifies a pointer to a string (an array of characters terminated by a null charac-
ter). Specifies the number of characters to be copied.
DESCRIPTION
The strncpy routine copies string s2 to buffer s1. The routine stops copying after it copies a null character or n characters, whichever
comes first. If the length of s2 as determined by the null character is less than n, the routine pads s1 with null characters.
RETURN VALUES
The strncpy routine returns a pointer to /NULL at the end of the first string (or to the location following the last copied character if
there is no NULL). The copied string will not be null terminated if the length of s2 is n characters or more.
SEE ALSO
Routines: bcopy(9r), blkclr(9r), copystr(9r), ovbcopy(9r), strcpy(9r)strncpy(9r)
