globbing, $# is too high after wildcard expansion in bash script
How can I pass in an argument such as "*.k" to a bash script
without having to double-quote *.k and not having *.k `glob` to match all files in the pattern? I tried using noglob in my script but this didn't work the way I thought it would.. expansion is still occuring, $# is higher than I expect. Code:
set +o noglob the other positional parameters that I'm passing in. Code:
# Test argument count
USAGE="USAGE: $0 <vertical> <src module> <files(s)> "
#
echo $# $0 $1 $2 $3
if [ $# -ne 3 ]
then
if [ $# -ne 1 -a $1 != "bdat" -a $1 != "cdat" -a $1 != "fdat" -a $1 != "blay" ]
then
echo $# $0 $1 $2 $3
echo $USAGE ; exit 1

We had this discussion in a similar thread recently I think. There's no way you can avoid the globbing occurring within your script because it is performed by the calling shell. If you can live with turning off globbing in your normal shell (which I suspect is unlikely) then you can turn it off there before running your script.
A suggestion here was to use an alias to turn off globbing, however there is no easy way to turn it back on automagically: UNIX Scripting - Turn off file expansion for command line arguments |

In shell programming / aliasing / set -f this was fixed by combining an alias and a shell function.

Nice solution; only seems to work in bash as you surmised in the referenced thread, but that'll be good enough for the OP!
