Shell Programming and Scripting

I don't understand noglob.

I have a function:

Code:

function no_globb ()
{
set -o noglob
echo "$1"
set +o noglob
echo "$@"
}

When I run the function like this noglobb *.txt
The ouput is:

Code:

file01.txt
file01.txt file02.txt file03.txt

Shouldn't it be

Code:

*.txt
file01.txt file02.txt file03.txt

That glob is expanded by the shell while parsing the command, which happens before the function is called. For your expected result, quote the argument to the function and use an unquoted $1 in both echo statements (globbing does not occur within quotes, so regardless of the noglob setting, "$1" will never ever lead to pathname expansion).
