Quick file allocation
Hi All, Just wondered on FreeBSD is there a way that I can quickly create a file. When I mean quick I basically mean that the system just says that ok this file is allocataed inodes foo-bar rather than having to use mkfile 1G filename. Something like XFS's holey file support Rgds Rus -- www: http://jvds.com | Virtual Servers from just $15/mo MSNM: [EMAIL PROTECTED] | Totally Customizable Technology e: [EMAIL PROTECTED] | FreeBSD Linux 10% donation to FreeBSD.org on each purchase ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Anyway, to create files of arbitrary size you can use the program truncate. For example, to create a 1GB file named test with truncate: # truncate -s1G test # ls -l test -rw-r--r-- 1 root wheel 1073741824 Jul 24 23:55 test For more information: read truncate(1) manpage. You may also want to take a look at dd (read dd(1) manpage).
