Если вы не знаете точный путь, вы можете использовать find2perl
. Он генерирует код File::Find::find()
для вас. Для немедленного выполнения команды:
$ find2perl /path/to/dir -name filename.txt -exec echo exists {} | perl
Код, сгенерированный find2perl

if 0; #$running_under_some_shell

use File::Find ();
# Set the variable $File::Find::dont_use_nlink if you're using AFS,
# since AFS cheats.
# for the convenience of &wanted calls, including -eval statements:
use vars qw/*name *dir *prune/;
*name = *File::Find::name;
*dir = *File::Find::dir;
*prune = *File::Find::prune;
