Top Forums UNIX for Advanced & Expert Users How to change the permissions of ksh? Post 302185134 by Heathe_Kyle on Monday 14th of April 2008 10:05:57 AM

If you don't have permission to execute ksh, then your administrator might have ksh locked down for some reason.

First, what shell are you running?

# echo $SHELL

Second, do you know the path to the ksh executable? What is the existing mode? On my system:

Code:
# whereis ksh
ksh: /usr/bin/ksh /usr/share/man/man1/ksh.1.gz
# ls -l /usr/bin/ksh
-rwxr-xr-x   2 bin      bin       315440 Dec  5  2006 /usr/bin/ksh


As you can see, the ksh file is executable by everyone. I can't think of a reason why your systems administrator would lock down ksh to a more restrictive mode. Give me an answer to the 2 questions I asked and we'll see where we can go from there.

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list. Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1). FILES
