发帖数: 8 | 1 recursively under a specific directory?
I write a perl, to recursive read files under all subdirectories, but failed
with error msg: "Bad symbol for filehandle" for the lime of code below:
if (!opendir($dirvar, $dirname)){
...............
so I'm thinking of "sac" or sth?
help! | t*u

Shell script:
% grep "your_pattern" * -R
Similarly in perl:
system ('grep', 'your_pattern', '.' ,'-R')
should work.
