Did not quite work as anticipated


xchbot1:/ford/app/oracle/product/920/dbs $ echo GANESH||TEST||MIST | awk -F '||' '{print $1}'

hi Ganesh,
there is a problem i m trying to sort it out.
by the time use this dirty solution

echo "GANESH||TEST||MIST" | awk -F '|' '{print $1}'

$3 will give TEST
$5 will give MIST

note the "" given around the string

one more thing use the -F '|'
and $3 for var2
$5 for var3


giving -F '||' is not working, its giving error even i am not able to work it out.

maybe some guru can throw some light on it

-F take only character in standred awk. Some advance version can take regexp as argument to -F
You can use an another (may be ugly) approach
echo "GANESH||TEST||MIST" | awk --posix ' {
split($0, a, /\|\|/) ;print a[1]" "a[2]" "a[3]" "a[4]}'

Code:
echo "GANESH||TEST||MIST" | nawk -F '\\|\\|' '{print $1}'

OR

echo "GANESH||TEST||MIST" | nawk -F '[|][|]'  '{print $1}'
