I actually did, but accidentally ran the old unix port. sorry for the noise.

clearly you did not run this script. this doesn't
work for the same reason that here docs in functions
don't work.

I guess I must be missing something, but this seems equivalent to your
bash script:
for(i in 1 2 3) {

Hello, so I repeat my question. While this is possible in bash: ;cat aBash for i in 1 2 3 do cat <

So you avoid a here document...
Then, is it so that a here document can't ever serve the purpose (ie.
it is limited in the way that any present variables are evaluated just
once; when then?)?
Thanks for a clarification!

i usually solve this problem like this
for(i in 1 2){
mkdir -p $i || fatal
cp POSCAR $i || fatal
@{

[9fans] problem with a here document in rc
Hello,
I have a problem with writing correctly a here document in rc.
I wrote, say:
s = (1 2)
for(i in $s) {
mkdir -p $i
cp POSCAR $i
@{
cd $i
ed POSCAR <[2]/dev/null
}
}
2c
$i
.
w
q
EOF
and I wanted to have the 2nd line of individual POSCAR files replaced
with the immediate value of $i.
But the script doesn't do it, and I don't know if it can be modified
in a simple way so that it did.
(I could possibly use sed [ie. without a here document] but ...)
If anyone can tell me...
Thanks!
Ruda
