instr() like function with awk

[pando]

Hi

Does anyone know if awk as any function which works as instr() sql function?

for example

echo kk.FmB | awk '{print substr($0, 1+index($0, "."),3) }'

this returns FmB

but if the file name has more than 1 . then I would be screwed!


cheers

try to use FS -> field separator and NF -> # of fields

echo abc.dfg.sss | awk -F. '{print $(NF), NF, FS}'
will print
sss 3 .

echo abc.dfg.sss | awk -F. '{print $(NF-1), NF, FS}'
will print
dfg 3 .


echo abc.dfg.sss | awk -F. '{print $(NF)}'
will print
sss
