Shell Programming and Scripting

I am trying to append a portion of a file with a date on it that changes daily to a temp file. Here are my commands:

set DATE = ('date +%Y%m%d_sum.log')

cat $HOME/right/$DATE > /export/home/temp.txt

Here is the error I keep receiving:

cat: cannot open /temp/usr/nedaniel/right/date
cat: cannot open +%Y%m%d_sum.log
No match

Can someone answer why the whole cat command is not being read and what I need to do to fix it?

Thanks.

Code:

DATE=`date +%Y%m%d`"_sum.log"

I'm still receiving the same error.

can you show the trace of the script?

Here is the whole script:

#!/bin/csh

rm /export/home/temp.txt

set DATE = 'date +%Y%m%'''d_sum.log'

cat $HOME/right/$DATE > /export/home/temp.txt

mailx -s "Job Sum <Log>" xxxxxx@xxxxxx.com < /export/home/temp.txt

I don't have any kind of trace. That is the whole script with this error:

cat: cannot open /temp/usr/nedaniel/right/date
cat: cannot open +%Y%m%d_sum.log
No match

set DATE = `date +%Y%m%d`"_sum.log"

Use backticks instead single quotes

Thanks for your help!
