I know that.

I had no other clues...
cat file1 file2 >file2
will tell you that the output file is an input file.
But using a redirect, the output of cat goes to a temporary file, and by
the time cat is done with the file as an input file, it can be written to.

No, because I need prepending. Contentent to be added to the beginning,
not the end.
Now, Lawson gave the accurate answer, as usual...
cat file1 file2 | cat >file2
works properly.
And for those who wonders what the heck I am doing, the full actual script
line look like...
echo '<tr><td><P STYLE="margin-bottom: 0in"><U><FONT
SIZE=+1>'$VERSION.$BUILD'</FONT></U></P><div
STYLE="position:relative;left:20"><a
href="binaries/'$PRODUCT-$VERSION.$BUILD'.tar.gz">Binaries</a><br><a
href="source/'$PRODUCT-$VERSION.$BUILD'-source.tar.gz">Source</a><br><a
href="'$VERSION.$BUILD'">Unzipped</a></DIV></td><td>'$TODAY'</td><td>'$COMMENT'</td></tr>'
| cat /dev/stdin /bali/products/$PRODUCT/archive/builds.log | cat
>/bali/products/$PRODUCT/archive/builds.log
I am creating a Log entry to be shown on my site, and I want the newest
entry first in that table.
I must again express my gratitude to all the people who has been involved
in developing the scripting capabilities and the other small little neat
utilities that works with streams. And if that would have been pushed a
bit harder, I would have gone Linux in the pre-1.0 times. As a developer,
it is just about invaluable to have it.
I am now also, slowly, modifying the web content to be updated through
scripts. "This site is maintained with BASH." Cute!!
Thanks again.
Niclas
