I think there may be something I dont understand fully.
The following code works well, but I dont like the set domen method.
So I looked in one of my books (Written by Chris FA Johnson) and on the web for a second example. The following doesnt work. You'll have to run it to see what I mean. Ill try to explain. As I run through the menu options to test, at one point or another, my option isnt read and the behavior is kind of like a back space. Even when using -n1 for read behavior was odd.
Chris' example does provide a function to do the reading of the options, but I want to understand whats going on here.
Does anyone know of a way to mimic the up arrow/down arrow type bash behavior within a shell script?
Say I have a scripted menu, and would like to be able to up arrow to bring up the last X number of lines of user input?
Thanks to anybody with a suggestion. :) (0 Replies)

I'm trying to understand if it's possible to create a set of variables that are numbered based on another variable (using eval) in a loop, and then call on it before the loop ends.

Hi all
Sorry for the basic question, but i am writing a shell script to get around a slightly flaky binary that ships with one of our servers. This particular utility randomly generates the correct information and could work first time or may work on the 12th or 100th attempt etc !.... (4 Replies)

I am trying to get my history in sync in multiple bash sections and things aren't working the way I expect.
Desired behavior, hitting esc-K in all bash sessions (same userid and machine) will use the same history.

Hi,
In the code "for loop" has been used to search for files (command line arguments) in directories and then produce the result to the standard output. However, I want when no files are named on the command line, it should read a list of files from standard input and it should use the command... (7 Replies)
