Re: [cobalt-users] RaQ4 - datestamp filenames in script

[Josh Kuperman <josh@xxxxxxxxxxxxxxxxxx>]

Oh good. I was so excited to finally see a question I can answer and
then Bruce beat me to it. Then I looked close and thought at least I
can

still mention that depending  on your shell perhaps you may have to
use `date +"%Y%m%d"`

so since I'm writing in emacs let me open a shell and see if I'm
right.Oh well guess not - though I'm pretty sure in scripts, perhaps
scripts using sh I had to have the parameters in double quotes .  

war-admiral:/tmp $ ls fingal
ls: fingal: No such file or directory
war-admiral:/tmp $ touch fingal`date +%Y%m%d`
war-admiral:/tmp $ ls fingal
ls: fingal: No such file or directory
war-admiral:/tmp $ ls fin*
fingal20030131
war-admiral:/tmp $ touch fingal`date +"%Y%m%d%h"`
war-admiral:/tmp $ ls fin*
fingal20030131  fingal20030131Jan
war-admiral:/tmp $
