I'm using Bash which doesn't have -A option for set and, from what I can tell, doesn't have an equivalent. I wish it did because you basically do what I need in a single line with your example.
I'm in the habit of using the following type of loop structure:
for num in `seq $1 $2`
do
command
doneWhile `seq $1 $2` is not exactly a huge resource hog, I would like to learn a better way. It seems that brace expansion is a good way to go:
for num in {3..10}The problem, though, is... (2 Replies)

So, I was bored on the train today, and was thinking of ways to loop through elements of an array. I came up with the following simple script, but it doesn't work as brace expansion doesn't seem to work with variables. Is there something I'm missing, or does the shell just not work like this?

shcomp
SHCOMP(1) Korn shell utilities SHCOMP(1)NAME
shcomp - compile a shell script
SYNOPSIS
shcomp [ options ] [infile [outfile]]
DESCRIPTION
Unless -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with
the same effect as the original script.
Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly.
If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages that need to be translated to
locale specific versions for internationalization.
If outfile is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from
standard input.
OPTIONS
[D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization. [n noexec] Displays warn-
ing messages for obsolete or non-conforming constructs. [v verbose] Displays input from infile onto standard error as it reads it.
EXIT STATUS
0
Successful completion.
>0
An error occurred.
