NAME
safe-rm - wrapper around the rm command to prevent accidental deletions
USAGE
safe-rm [ ... ] (same arguments as rm)
DESCRIPTION
safe-rm prevents the accidental deletion of important files by
replacing rm with a wrapper which checks the given arguments against a
configurable blacklist of files and directories which should never be
removed.
Users who attempt to delete one of these protected files or directories
will not be able to do so and will be shown a warning message instead.
safe-rm is meant to replace the rm command so you can achieve this by
putting a symbolic link with the name "rm" in a directory which sits at
the front of your path. For example, given this path:
PATH=/usr/local/bin:/bin:/usr/bin
You could create the following symbolic link:
ln -s /usr/local/bin/safe-rm /usr/local/bin/rm
CONFIGURATION
Protected paths can be set both at the site and user levels.
Both of these configuration files can contain a list of important files
or directories (one per line):
/etc/safe-rm.conf
~/.safe-rm
If both of these are empty, a default list of important paths will be
used.
/usr/lib/*
will protect all of the files inside the /usr/lib directory if they are
referred to directly, but it will not protect your system against:
rm -rf /usr/lib
For a full protection, you should include both of these lines:
/usr/lib
/usr/lib/*
EXIT STATUS
Same exit status as the real rm command.
Note that if all file arguments are skipped by safe-rm then the exit
status will be the same as the exit status of the real rm when no files
arguments are present.
BUGS AND LIMITATIONS
Note that if you put the following in your protected paths list:
$ cat /etc/safe-rm.conf
/usr/lib
Then safe-rm will prevent you from deleting the directory:
$ rm -rf /usr/lib
Skipping /usr/lib
/bin/rm: missing operand
Try `/bin/rm --help' for more information.
However it cannot protect you from the following:
$ cd /usr/lib
$ rm -f *
