No. No.
Do not replace anything in /bin. Plus /bin is a link to /usr/bin. You will break zillions of things you had no idea about. So do not do that. The system could fail on shutdown or reboot due to a problem in your code. Then you have a dead box. Or a doorstop if you need one.
Create an alias in /etc/profile
Put your code in /usr/local/bin, this will prevent system users from using the altered rm.
/usr/local/bin is meant for this kind of thing - non-standard applications available to all users. If you put other command utilities into /usr/local/bin, add it that directory to your PATH variable.

On AIX 5.2 as root, installed Seamonkey and have to type
#/seakey/seamonkey/seamonkey to get it to run, which it does okay.
To set up a permanent alias, I did the following
(1) In a text editor
alias seamk='/seakey/seamonkey/seamonkey'
and saved it to /home/alias_file
(2) In a text editor... (7 Replies)
Hi guys,
I'm running Solars 8 on a V100 server at home for testing.
If I switch user to root and do:

This is the output:

I'm using rsync over ssh and need to add /usr/local/bin and /user/local/sbin.
I do this by running the line:

I try to understand the meaning of an inode. I wonder whether
an inode is unique (I'm pretty sure it is) and
whether it remains the same inode regardless of whatever happens to the file, dir or whatever?
I read somewhere that an inode stores info about the file, size... so changing the... (4 Replies)
Is there a way to make a permanent pseudo-file, whose contents may dynamically change? I'm thinking of something like an SQL view here. I've been trying to do this with pipes, but I haven't been able to crack it.
For example, I have two files, “half1” and “half2”, which are subject to change... (3 Replies)

smrsh
SMRSH(8) System Manager's Manual SMRSH(8)NAME
smrsh - restricted shell for sendmail
SYNOPSIS
smrsh -c command
DESCRIPTION
The smrsh program is intended as a replacement for sh for use in the ``prog'' mailer in sendmail(8) configuration files. It sharply limits
the commands that can be run using the ``|program'' syntax of sendmail in order to improve the over all security of your system. Briefly,
even if a ``bad guy'' can get sendmail to run a program without going through an alias or forward file, smrsh limits the set of programs
that he or she can execute.
Briefly, smrsh limits programs to be in a single directory, by default /usr/lib/sendmail.d/bin/ allowing the system administrator to choose
the set of acceptable commands, and to the shell builtin commands ``exec'', ``exit'', and ``echo''. It also rejects any commands with the
characters ``', `<', `>', `;', `$', `(', `)', `
' (carriage return), or `
' (newline) on the command line to prevent ``end run'' attacks.
It allows ``||'' and ``&&'' to enable commands like: ``"|exec /usr/local/bin/filter || exit 75"''
Initial pathnames on programs are stripped, so forwarding to ``/usr/bin/vacation'', ``/usr/bin/vacation'', ``/home/server/mydir/bin/vaca-
tion'', and ``vacation'' all actually forward to `/usr/lib/sendmail.d/bin/vacation''.
System administrators should be conservative about populating the /usr/lib/sendmail.d/bin/ directory. For example, a reasonable additions
is vacation(1), and the like. No matter how brow-beaten you may be, never include any shell or shell-like program (such as perl(1)) in the
/usr/lib/sendmail.d/bin/ directory. Note that this does not restrict the use of shell or perl scripts in the /usr/lib/sendmail.d/bin/
directory (using the ``#!'' syntax); it simply disallows execution of arbitrary programs. Also, including mail filtering programs such as
procmail(1) is a very bad idea. procmail(1) allows users to run arbitrary programs in their procmailrc(5).
COMPILATION
Compilation should be trivial on most systems. You may need to use -DSMRSH_PATH="path" to adjust the default search path (defaults to
``/bin:/usr/bin'') and/or -DSMRSH_CMDDIR="dir" to change the default program directory (defaults to ``/usr/lib/sendmail.d/bin/'').
FILES
/usr/lib/sendmail.d/bin/ - default directory for restricted programs on SuSE Linux
