1. The problem statement, all variables and given/known data: Find the first letter in alphabet from the input:
Accept the input of a series of upper case alphabetic letters one at a time. The input ends with a 0. Find and display the first letter in alphabetic order. For example, input of D, G, T, S, V, G, C, K, P should result in C.
2. Relevant commands, code, scripts, algorithms:
P.S. I am using cygwin in windows to do this script.
3. The attempts at a solution (include all code and scripts):
Im not sure how to tackle this question so im asking for tips and pin pointers.
Basically what i think i should do is use a while loop and the shift command to take in the letters one at a time (But i heard shift deletes the first input so im not sure if its possible) then use an nested if statement
to get rid of any non alphabetical inputs with an else to give an error.
THen thats where im stuck. How would someone find out the first letter from a given amount of letters?4. Insearch: (University of Technology Sydney), Sydney NSW, Australia, James Hu (web systems), www(dot)insearch.edu.au/default.aspx?ArticleID=430

I've looking over a script for work and I've had a problem with the script not listing the files in alphabetical order. To look up PIDs for apps, it would be beneficial to have them listed in that order. Here is what I've been reviewing.

BASE64(1) User Commands BASE64(1)NAME
base64 - base64 encode/decode data and print to standard output
SYNOPSIS
base64 [OPTION]... [FILE]
DESCRIPTION
Base64 encode or decode FILE, or standard input, to standard output.
-w, --wrap=COLS
Wrap encoded lines after COLS character (default 76). Use 0 to disable line wrapping.
-d, --decode
Decode data.
-i, --ignore-garbage
When decoding, ignore non-alphabet characters.
--help Display this help and exit.

The data are encoded as described for the base64 alphabet in RFC 3548. When decoding, the input may contain newlines in addition to the
bytes of the formal base64 alphabet. Use --ignore-garbage to attempt to recover from any other non-alphabet bytes in the encoded stream.
