The problem is when I run it at command line, it works, but not in

works well. However, the script mystmp:

newstmp=$1
touch --date=$newstmp t1
and run mystmp as:

What's wrong? Thanks!
The problem is that the parameter has spaces within it, so when you
use that as
a variable within your script, you need to enclose it with quotes. Your script
currently expands that command to something such as:
touch --date=Tue Aug 22 08:30:00 CDT 2006 t1
which - since the "Aug," "22," "08:30:00," etc files don't exist -
creates them
and sets their timestamps to the current time. You need to use --date="$1" so
that the command is interpreted as you had intended:
touch --date="$1" foo.file
That would expand to something such as:
touch --date="Tue Aug 22 08:30:00 CDT 2006" foo.file
which is what I believe you are intending to do.
Hope that helps.
