Re: [SLUG] script permissions, etc
It's a good idea to use variables for storing the filenames used.
It's also a good idea to use an absolute path when accessing the file.
eg:
my_user = voytek
ccc_final = /var/tmp/ccc
ccc_html = http:.../ccc.html
ccc_txt = /var/tmp/ccc.txt
ccc_bod = /var/tmp/ccc.bod
wget ... $ccc_html
...
links -dump $ccc_html $ccc_txt
...
awk '/Page/, /References/ { print }' $ccc_txt $ccc_bod
...
mail -s ccc list $my_user $ccc_final
etc.

script fetches a html page, parses it several times, then emails some text

when starting the script should I say 'cd /var/tmp' (to have temp files
in/var/tmp?)
should I prefix full path to intermediate files ( /var/tmp/body.txt?)

Re: [SLUG] script permissions, etc
Tmp has special permissions only the person that created it can delete it and
generally global write is not enabled
Clan up the tmp file reliably and you should have no problems.
The is also a make temp call that gives you a reliably unique filename
