Top Forums UNIX for Advanced & Expert Users How to prevent Accidents 'rm -rf *'? Post 302904224 by cero on Tuesday 3rd of June 2014 02:37:48 AM

One way would be alias rm to a script that checks its parameters:
Code:
alias rm='/usr/local/bin/myrm.sh'

Code:
#!/bin/bash
# script: myrm.sh
# check parameters to prevent system damage

[ "$*" = "-rf $(echo /*)" ] && echo "Illegal parameters" && exit 1

/bin/rm $@

Edit: as Don Cragun was faster I'll explain how I interpreted the OP: his problem is invoking commands via a third party tool which does not check the parameters it passes.

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME
getusershell, setusershell, endusershell - get legal user shells SYNOPSIS
#include <unistd.h> char *getusershell(void); void setusershell(void); void endusershell(void); DESCRIPTION
The getusershell() function returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells. If /etc/shells does not exist, the following locations of the standard system shells are used in its place: /bin/bash /bin/csh /bin/jsh /bin/ksh /bin/pfcsh /bin/pfksh /bin/pfsh /bin/sh /bin/tcsh /bin/zsh /sbin/jsh /sbin/pfsh /sbin/sh /usr/bin/bash /usr/bin/csh /usr/bin/jsh /usr/bin/ksh /usr/bin/pfcsh /usr/bin/pfksh /usr/bin/pfsh /usr/bin/sh /usr/bin/tcsh /usr/bin/zsh /usr/xpg4/bin/sh The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells. The setusershell() function rewinds the file or the list. The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells. RETURN VALUES
The getusershell() function returns a null pointer on EOF. BUGS
All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved. SunOS 5.10 30 Aug 2004 getusershell(3C)
