atentie:
[EMAIL PROTECTED] cata]$ echo 1 2 3 | read a b c ; echo $a $b $c
[EMAIL PROTECTED] cata]$
(adica nimic)
pe cind
[EMAIL PROTECTED] cata]$ echo 1 2 3 | while read a b c ; do echo $a $b $c ;
done
1 2 3
[EMAIL PROTECTED] cata]$
chestia e ca `|' deschide un nou proces si pierzi variabilele respective.
poti sa incerci un:
eval `echo $linie | awk '{printf
"fileld1=%s;field2=%s;field3=%s;field4=%s\n", $1, $2, $3, $4}'`
sau cel mai elegant e sa scrii tot in awk.
