For (t)csh: alias rm rm -i For (ba)sh: alias rm=rm -i Now that you've learned :). Martin's suggestion is good though -- would have done that considering that all that lived in /usr/local were ports. -Garrett The problem with this is that it will ask confirmation for every file it deleted. Which is gets pretty annoying after a while, also, if you delete a directory containing a 100 files, you will have to press 'y' a 100 times. This will probably lead to the habit of using 'rm -f', and/or simply pressing y all the time without actually looking at the confirmation message. In any case, it's not likely to prevent any such accidents. For the sake of it: You could use rm -I: quoting the rm man page: -I Request confirmation once if more than three files are being removed or if a directory is being recursively removed. This is a far less intrusive option than -i yet provides almost the same level of protection against mistakes. Output looks like this: # rm -fI * remove 10 files? Would even be better if it would list e.g. 2 or 3 files. A better solution would be to write a script that would move files instead of deleting them. You should name this script to something else than rm, when you're working with a new or foreign system, you will expect rm to move files, instead of deleting them ... and we can all see another disaster coming there... true, sometimes fingers have a memory of their own ;) Another hint would be the 'rmstar' option in tcsh, when set, tcsh will ask confirmation before executing 'rm *'. Note that aliasing 'cp' and 'mv' to 'cp -i' and 'mv -i' is an *extremely* wise idea, in the past I have often accidentally overwritten files that should not have been overwritten, leading to various problems. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Query file system type for yet-to-be mounted volumes?
Modulok typed on 07/05/07 11:02: How does one determine the file system a disk uses, for disks that are not yet mounted? Example: You're handed a disk that has been sitting around in a closet for years, with no idea what it was used for. The department manager tells you to see what it contains. How do I mount it, if I don't already know what file system it uses? Is there a command to query this? Trial and error doesn't seem like the ideal solution. You might get a clue using file: eg: # file -s /dev/da0s1 /dev/da0s1: x86 boot sector, code offset 0x3c, OEM-ID MSDOS5.0, sectors/cluster 32, root entries 512, Media descriptor 0xf8, sectors/FAT 250, heads 255, hidden sectors 32, sectors 2044383 (volumes 32 MB) , serial number 0x64650d9b, unlabeled, FAT (16 bit) see man file As far as I am aware parted or gparted (partition-editor running on Linux) is not in ports, but there is a 50MB-live-cd availabe: http://gparted.sourceforge.net/livecd.php but you might want to check the features first. -Modulok- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

rm '--preserve-permissions'

What should I do :-)
rm -- '--perserve-permissions'. -- tells getopt to stop searching and
the single quotes are a double bonus because it doesn't interpret the
string contents beforehand, but instead passes it on as a straight
string.
Try: rm --perserve-permissions and rm '--perserve-permissions', in
that order to just see what happens ;)..
-Garrett
Haha. Forgot that the single quotes version won't work by itself. It's
basically for cases when there are shell sensitive characters inside a
string, when compared to the double quotes. The first solution with --
will work though, guaranteed :).

You should always be able to delete files per inode, which is quite
handy with files containing special characters.
ls -i *
2324367 foo
find . -inum 2324367 -exec rm {} \;
Saves me a lot of hassle.

Re: How to use vsftpd with wirtual users without LinuxPAM ?
Quoting Vincent Bolinard [EMAIL PROTECTED]: Hello, I'd like to know how can I set up virtual users without pam_userdb.so (which is not included in OpenPAM). vsftpd needs pam_userdb.so to authenticate against the db Berkeley database. What else can I use ? I don't want to use MySQL because there won't be a lot of virtual users ( 50). Thank you for your help. Basically you can use any authentication method provided by OpenPam. For Users 50 pam_pwdfile.so should fit your needs, esp. if you are familiar with htpasswd.

Re: Cron [EMAIL PROTECTED] /usr/libexec/save-entropy
Quoting Martin McCormick [EMAIL PROTECTED]: I must have dome something wrong setting up a FreeBSD5.4 system, but I haven't a clue as to what. The script is called save-entropy, a great idea, but it acts as if lots of the configuration it needs is missing. I do have ipfw running and it got all the rules I put in to it via a rule-setting script called in rc.conf.local but the message that cron generates every eleven minutes shows that something is very unhappy. For now, I simply commented out the save-entropy run for a bit of peace and quiet, but the entropy is now not being updated which is not a good thing. What do I need to look at to fix this properly?

Re: vsftpd pam problem
Quoting Terry [EMAIL PROTECTED]: Hi going by the docs for virtual users i have got to this file vsftpd.pam auth required /lib/security/pam_userdb.so db=/etc/vsftpd_login account required /lib/security/pam_userdb.so db=/etc/vsftpd_login From google i gather pam_userdb.so isn't part of OpenPAM which is what FreeBSD uses. So how do Freebsd users get round it or am i missing some thing really silly. In my understanding this is correct. There's no pam_userdb.so available for FreeBSD. You could use pam_pwdfile.so, which is in the ports-collection. Users are added/changed e.g. through htpasswd. Works well if you have not a lot of accounts. a simple vsftpd.pam could look like this: auth required/usr/local/lib/pam_pwdfile.so pwdfile /etc/vsftpd_login account required/usr/lib/pam_permit.so Thanks ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
