No, tak jsem nechtene prisel na rozdil mezi "|" a "<" :

bazil na shogun:~$ cat > nts <<EOF
> wrg
> werg
> reg
bazil na shogun:~$ echo $HHH

bazil na shogun:~$ cat nts | read HHH
bazil na shogun:~$ echo $HHH

bazil na shogun:~$ read HHH < nts
bazil na shogun:~$ echo $HHH
bazil na shogun:~$ 

huh? Jsem sice dneska nejaky ospaly ale tohle z boku neodstrelim asi ani
normalne. Takze, proc to z trubky nechce cist jak si predstavuji a pri
"<" to cte? Nakopne me nekdo kde je rozdil?
