No. The different parts of the pipeline starts up independentlyQuote:> echo "$(cat bigfile)" | sed s/foo/bar/ > bigfile # is this
> safe?
sed 's/foo/bar/' bigfile >bigfile.new
mv bigfile.new bigfile
That's a command less, uses less memory, and is perfectly safe.

I just read in a book that to one way to find out the value of an
enviroment variable is to give it as the argument to echo, preceded
by a $ and surrounded by double quotes, as in echo "$FOO". Why
the quotes? It seems that I get the same results whether I do echo
$FOO or echo "$FOO".
Thanks!

5. 'echo "some text" |read foo' results in empty $foo
6. ISAM error
7. What is the diff. between "sh foo" and "foo"?
9. What is the meaning of "foo" and $foo"?
10. foo=X%XY%Z; echo ${foo//X/w} works;echo ${foo//%%/p} NotWhatIwant
11. Solaris 8 box: cat file | rsh solaris_2.6_box "cat > /dev/null" SLOW
12. Type 'yes > bigfile &' on your system
