Hi, Someone at work told me that doing "du -a <DIR>|grep <FILE>" is faster then "find <DIR>|grep <FILE>". I've measured, it doesn't looks quite so. It did OTOH got me wondering what's the quickest way to answer if file existed in a hierarchy of directories.
Assuming I'm not interested in any information besides the answer if file existing or not. I would only need to access the directory listing and not the inode of each file, right? Is there some utility that can do this very simple search efficiently? real 0m8.445s user 0m0.198s sys 0m0.636s [EMAIL PROTECTED] /]$ time find usr/ real 0m21.405s user 0m0.332s sys 0m1.524s [EMAIL PROTECTED] /]$ time du -a usr/ real 0m9.228s user 0m0.992s sys 0m1.304s [EMAIL PROTECTED] /]$ time ls -1R usr/ Thanks, -- Cheers, Maxim Veksler "Free as in Freedom" - Do u GNU ? ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
